[!!] Windows Minecraft loads login, loads world, but instantly crashes. It started at the exact same time I placed a minecart.

[!!] Windows Minecraft loads the login page, but won't start up after hitting login. Minecraft stays blank for about 10 seconds, and then comes up with a video card driver error. All Drivers are updated and working with everything else, however. Running Windows 8 Professional 64-bit, using MSI Radeon 4300/4500 Series with latest drivers installed. AMD Athlon II X3 Processor at 3.10 GHz and 8 GB RAM.

  • The latest drivers may not be latest enough. Go send your card manufacturer an email or something, it doesn't seem like Mojang can fix this. Pokechu22 23:06, 3 October 2012 (UTC)

[!!] macOS Minecraft will load the main menu but will not load a SSP world, or a SMP server.

I can't get the online demo to work it crashes and i get this message.

  • Try using a pc instead of a mac, it seems that MAC OS has many more minecraft related bugs than the pc version, probably because minecraft started on pc, then migrated to MAC OS.

[!!] macOS Minecraft crashes when typing slash "/" to open up command, shortly after entering the world. I was in creative mode. The world is new. I was able to repeat it many times. I hava Java 7 installed but Minecraft doesn't seem to be using it. Not sure how to force that, or whether Java 7 is currently supported by Minecraft on a Mac.

  • The only way to get MInecraft to use Java 7 on a Mac is to use the MinecraftLauncher.jar, but that causes it to crash straight after the 'Done loading' screen on a lwgjl exception. --dlminecr 12:01, 1 October 2012 (UTC)

[!!] My apologies if I post this incorrectly, I am new to minecraft and this is the first time I ever posted to a wiki. I open the inventory screen by pressing E, when I close the screen by pressing E the game crashes and I get a crash report. I am running win7 on an i7 laptop with an ATI 5730 graphics card. I have a crash report.

I fixed the markup in your post above, but all I can suggest is to also ask at the minecraftforum and/or the #minecrafthelp channel on IRC for expert analysis. Although the crash log *appears* to show an unmodded minecraft and a correct Java install, I would try a complete uninstall of Java, reinstall the same Java, do a clean install of Minecraft (in a separate folder, or ask how to do this), and retry. -Aurelius 07:34, 3 September 2012 (UTC)

[!!] Inside the inventory, if I move my mouse, the game and the computer will crash. This bug has appeared in previous versions of Minecraft, and someone has always kindly provided a patch to fix the problem, which appears to be with the 'Steve' character following the mouse. However no patch yet exists for the latest version.

When it was fixed before, the character box was blacked out, and thankfully, I was able to play. System: laptop, Windows Vista, 2GB Memory, 120 GB Hard Disk, Intel Pentium Dual Core.

Could someone please patch this, and perhaps Mojang could fix this recurrent bug, which appears to affect a number of people in the Minecraft blogosphere.

  • I made sure that I had updated to Java 7 Update 7, but unfortunately, the inventory problem persists. 01/09/2012
  • I looked into the 64 bit version of Java, and it seems that my system is of the 32 bit variety. My render distance is short, the graphics are set to 'fast' and clouds are off. Yet the inventory crash still happens. –Preceding unsigned comment was added by (Talk|Contribs) 19:33, 30 August 2012 (UTC). Please sign your posts with ~~~~
Please link to previous mentions of this bug and the patch. Please ensure you are using a clean install of vanilla minecraft 1.3.2, no mods, no snapshots. Please include the crash log here or at minecraftforums. -Aurelius 07:50, 3 September 2012 (UTC)
I would also try Tutorials/Update LWJGL because it appears you have an old version (2.4.2 rather than the latest 2.8.4). -Aurelius 09:08, 3 September 2012 (UTC)
  • I am using a clean installation of Minecraft without mods etc.. Unfortunately, the .bat file is not saving the crash report as when the crash comes it stops everything dead so that I have to press the restart button. I suspect that the computer is paralysed to the point of not recording the log. However the link to the old InvFix patch is here:

[!] When launching Minecraft, I get to the Singleplayer\Multiplayer selection screen after the Mojang splash screen. At this point, it freezes. I am not able to select any of the buttons. I have deleted the app and re-installed. Occasionally, I am able to select the options button or the multiplayer button but mostly it just hangs. Occasionally, I can quit but mostly have to Force Quit. In background, I am trapping

GL ERROR @ Pre render 1281: Invalid value

A very similar report was posted here. I've not much experience with pre render errors, but I'd first look at ensuring the texture pack was default (after ensuring it's 100% vanilla 1.3.2, no mods, no snapshots, completely clean install); then remove all files from the texture folder; then retry and get the crash log and post it here or at minecraftforum or at the #minecrafthelp channel on IRC. -Aurelius 08:23, 3 September 2012 (UTC)

[!!] In creative mode, I press E, then it crashes. This all started to happen after the latest update.

Try Tutorials/Update LWJGL because it appears you have an old version (2.4.2 rather than the latest 2.8.4). -Aurelius 09:08, 3 September 2012 (UTC)

[!!] I bought a new graphics card, Gforce 210. I am running Windows XP Professional, Service Pack 3, AMD Dual Core 4450e, 2.31 GHz, 2.75 GB of RAM. Before I put graphics card in. I ran the game in low video and performance: balance. I had no issues with lag or freezes. After putting my card in, the issues started.

1. Install graphics card and drivers
2. Login to game.
3. Start walking using default settings.
4. Scroll through the inventory by using the mouse scroll button while walking.
Result: Game freezes.

When I took the card out I did not have this issue. However, I would like to be able to play the game using my new graphics card.

[!!] When in Multiplayer, Doing direct connect and pressing "Join Server" it crashes sometimes.

[!!] When in Multiplayer, choosing a server and double clicking it or pressing join server will crash minecraft sometimes

[!!] Minecraft crashed on attempting to join a Multiplayer server-- 02:01, 31 August 2012 (UTC)

[!!] macOS Minecraft simply won't launch at all. After unzipping and clicking the APP it just says "Minecraft is broken and it can't be started. Move to trash/Cancel". I think it has something to do with the zip file but i can't know for sure... Also impossible to add crash report since there is no CR. I did not have any problems before 1.3 update. I have iMac with latest OS. And yes I have checked for updates and my java is uptodate. Tested also with my MacBookPro (older os), won't work. Fix would be appreciated :) -- 18:00, 21 August 2012 (UTC) FoleyQ

  • This is because Gatekeeper blocks the file, as it hasn't been signed, but because of the way a .app launches a .jar file, it doesn't present the same dialogue box as any normal unsigned .app. I believe signing the .app with a Developer ID ( would fix this issue. Jrtc27 10:25, 23 August 2012 (UTC)

[X] i can't play the game because after it says java everything is with complete lag and even if i cilck something it does do anything, just moves extremely with a ton of lag. It hasn't crashed/freeze (only if minecraft is not responding) so i try re-installing Minecraft/deleting .minecraft folder and go on minecraft for it to download packages almost everyday, Im not know why its doing this but i can play other random games etc. its sad 'cuase i only gotta play the 1.3.2 minecraft update once and also even the browser minecraft doesn't work so i really am confused. –Preceding unsigned comment was added by (Talk|Contribs) .

[!!] Whenever I go into a mutiplayer server, it seems to always crash, with a slim chance of it working. It never happened to me with 1.3.1. Here's the crash report:

  • Never happened with 1.3.1? Crashes with this JRE version (Java 6 Update 15) have been reported. In any case, your Java is way out of date and this is almost certainly the cause of your problem. -- Featherwinglove 12:29, 18 August 2012 (UTC)

[!!] [MOD] Random crash when entering a bukkit-mulitiplayer server.

[MOD] Here's a report from [my] PC. It just crash[ed] when making a new seed.

  • I fixed the grammar and capitalisation, put the bug in the correct section, the crash report inside a crash template for you and added the crash bug tag. Please pay more attention to grammar and capital letters next time - it makes your report just that bit harder to read, and that in turn makes Mojang's job harder than it needs to be. -- 22:51, 17 August 2012 (UTC)
  • Is your minecraft modded? -- 05:55, 18 August 2012 (UTC)
  • Update your Java, you are using 6u22; the current version is 7u5. -- Featherwinglove 12:29, 18 August 2012 (UTC)
  • Java version is quite unlikely a cause in this case, Minecraft can run on Java all the way back to version 1.5. It is probably just a glitch. --Wormy14 20:30, 19 August 2012 (UTC)
  • Forgive me for having doubts about that, since I had the crash problems I was having with Release 1.2.5 solved by updating my own Java when I had first purchased Minecraft. -- Featherwinglove 01:08, 1 September 2012 (UTC)
Anybody else notice "Very likely" for modded? Is your Minecraft modded? Because that would be the problem.
  • "Very likely" shows when you delete the "META-INF" folder.Minecraft5025 15:23, 28 August 2012 (UTC)

[!!] This is my crash report file:

--Shauna 08:35, 20 August 2012 (UTC)

[X] [LMP] On Debian, /etc/hosts usually maps the laptop's own hostname to, an alternative loopback address (e.g. " mylaptop.mydomain mylaptop" - all of is loopback). When a Minecraft-on-Debian user advertises their single-player game to the LAN, the multicast announcement comes from their LAN IP address (e.g., but the server only listens on and announces that address in the multicast packet, e.g. [AD][/AD], making other machines unable to join. --smcv

  • This isn't a Minecraft bug. Your host config is broken - i.e. it says your host name is the loopback device, it happens on other OSes as well. At best it is a feature request where the "Open to Lan" form should ask what NIC you want to open the game on -- Warjort
  • It's the standard configuration for at least Debian 6 and Ubuntu 11.10, and anything with libnss-myhostname - they map the hostname to loopback because a typical desktop/laptop doesn't have any other permanent addresses, only temporary DHCP-assigned addresses, and various apps (like Minecraft) make the mistake of assuming that the result of hostname() is a meaningful DNS name (on a typical desktop/laptop, it isn't). If Minecraft listened on or :: (all local IPv4 or IPv6 addresses at once), and used the address from which it received the multicast advertisement as the address to connect to, it wouldn't need to distinguish between NICs at all, and LAN games would "just work". --smcv
  • Actually that's a common misconception, is the "any" address not the "all" address. But I would agree that it is probably a better default than java's InetAddress.getLocalHost().getAddress() which is what appears to be used currently.
  • This is actually an issue with any OS except Windows, due to the loopback interface. If this interface was ignored when opening a server to LAN, then every other system would work as well as Windows in this regard. Either that, or just bind to Either way, it's trivial to fix. --Zorander

[!!] Any time I try running Minecraft, I get an instant crash from the Mojang splash screen. This also happened right after updating, so my .jar is vanilla. --TheUltamate 04:14, 21 August 2012 (UTC)

  • I've seen alot of null pointer exception errors, some from myself. And i think ive seen this error before. Try going into the .minecraft folder and delete a folder named 'bin' then redownload the game from the launcher. If that doesn't work, try checking for corrupted files or other programs possibly interfering with it. If nothing works go get a nerd.

[!!] i was lighting a lot of stuff on fire, and the game froze and gave me this error report. no mods

  • I have experienced this bug when I was playing on (hosting) a LAN server. I had been placing a lot of TNT and exploding it, and it exploded, then crashed. It gave a similar error as below, but the game said that two different classes, farther apart in order, were attempted to be mapped like that. --Wormy14 19:16, 14 September 2012 (UTC)
  • Here it is.

Afterwards, I observed a single block of TNT exploding as I relogged, within the first second of the level being loaded.

Note: I had to remove most of the entity data, the data wouldn't send. It just returned a blank screen, like, five times. Probably because it took up half the page... --Wormy14 21:32, 14 September 2012 (UTC)

[!!] Minecraft silently crashing at random, here's my java crash log:

note that MCedit schematics is JUST the name of the world where i put all my schematics.

[X] macOS When using a non-QWERTY keylayout (such as Dvorak), the upper row of keys (",.PYFGCRL/=) still acts as a QWERTY keyboard (QWERTYUIOP[]). This results in two different E keys, but no I key, among other issues. —Fenhl 11:17, 16 September 2012 (UTC)

  • Dvorak appears to be the only affected layout. At least AZERTY and QWERTZ work fine. —Fenhl 11:26, 16 September 2012 (UTC)
  • Dvorak is affected, because the actual bug is like this: Minecraft tries to convert keys that aren't A-Z to US-QWERTY equivalents. In Dvorak, the QWE equivalents are hyphen, comma and dot. The Z equivalent does a similar thing, it's semicolon in Dvorak, so it gets replaced with Z. This bug will affect all keyboards which have the A-Z letters in different places than QWERTY.


[A] When quitting the game and returning to the menu I get this stackstrace. When restarting the last changes seem not to have been saved.

[A!] macOSNow that the Minecraft client itself can be a server, the OS X firewall is unhappy. Every time I open Minecraft, a firewall warning quickly pops up and disappears. This has always happened, but now the first time I go into the Multiplayer screen (after every launch) the same firewall warning appears, giving me the option to "Allow" or "Deny" from "accepting incoming connections". What makes this most annoying is that to allow it through the firewall, it requires an administrator's password. I've tried manually adding the .app and .jar files to the firewall's list and setting them to allow, but even that doesn't work. However, there is one fix - to codesign the .app, as the firewall automatically allows signed apps through it. I can also confirm that this fixes the issue, as I used my own certificate and key-pair to sign the app through Terminal, and it no longer produces the dialogue box. See for more information about signing the .app. Jrtc27 10:35, 23 August 2012 (UTC)

[A] LinuxWhen repeatedly clicking in Ubuntu 12.04 (other Ubuntu versions/other Linux untested) the cursor unlocks from the game. When this happens, any keys pressed do not register release. This is annoying most often when fighting mobs, especially near lava, as it means that clicking ability is reduced as well as the deadliness of accidentally walking into lava (with all your precious gear and xp). 14:57, 21 September 2012 (UTC)

[X] (On Minecraft 1.3.2, however I have not tested this on any other versions). I fell really far down and died on SSP. Then clicked on the "Respawn" button very quickly; almost as soon as it popped up. After respawning, another character (with my skin, my name above their head, etc.) appeared and followed me, perfectly mimicking all my movements. It disappeared after a short time, but reappeared every now and then, sometimes far away from me. I tried hitting it and I took damage, then eventually "killed myself". A notification popped up in the chat section that said "(Username X) was slain by (Username X).

[X] [MOD] (I download some mods today like, xray mod, the optifind mod, and rei's minimap mod. My minecraft game worked perfectly after i download the xray and the optifind mods, but right after i downloaded rei's minimap mod my game would crash. I could log in and go to the menu, but once I click world minecraft freezes for a few seconds and than a crash report comes up. Does this mean that the rei's minimap is bugged or something? According to this crash report it seems like it has nothing to do with the rei minimap mod. Here is my crazy report:

  • This is because xray, and reis minimap don't like each other, so they fight, and xray go complains to the client, and he breaks it up, but stops the game and yeah, uninstall one of them.
  • Did anyone notice "Is Modded" says "Very Likely"? You are modding your MC, so this is not a MC bug. Removing tomorrow. --Blackbird626 13:39, 7 October 2012 (UTC)

so this is first time posting on here and when i play singleplayer i can play for a little bit. then a message will pop up and say out of memmory i don't know what to do

[A] Linux Minecraft doesn't integrate well into modern Linux desktop environments like Gnome Shell because it doesn't set a proper application name. Unfortunately Java doesn't provide an API for this but it is possible to set this application name via Reflection. This blog post describes how to do it (See the Java Code at the end of the article). Would be nice if Minecraft could do this itself so this hack is no longer needed. --Kayahr 07:39, 3 October 2012 (UTC)

[!!] Minecraft keeps crashing on my son. I am not good with computers. My brother updated Java, but it still happens. He can play for a while and then it just shuts off and we have a message on the desktop. Here is the report. I appreciated any help.

[X] Not sure if this is the right place for this, but Minecraft does not save the last server connected to with direct connect when you exit the game. This is a bug because in opions.txt in .Minecraft, there is a field, lastServer:, that seems intended for this purpose.Pokechu22 23:01, 3 October 2012 (UTC)

Demo version[edit]


[X] I'm not sure where to report this. So I understand if the demo is bugged but when I try playing Minecraft Classic it tells me "An error occurred while loading the applet. Please contact support to resolve this issue. Fatal error occured (5): A device attached to the system is not functioning" meanwhile the Demo says "Failed to launch Fatal error occurred (5): A device attached to the systeem is not functioning Extracting: windows_natives.jar.lzma to windows_natives.jar." I have played this game on my cousin's computer and I am really wanting to buy it but I am worried that this error will happen on the actual Minecraft game. Anyone have any ideas about this? --Jason –Preceding unsigned comment was added by (Talk|Contribs) . Please sign your posts with ~~~~

  • Does not belong here, because bug in Minecraft Classic. --Kumasasa 05:54, 21 August 2012 (UTC)

  • Why don't you play the demo of the current Minecraft version ? Go to Minecraft Demo, register an account and play !--Kumasasa 06:09, 21 August 2012 (UTC)
  • That is the other problem. The demo hasn't been working just like Minecraft Classic so I have no idea if the actual game will work. --Jason
  • It asks if I want to update if I say yes it tries to load but then says "Failed to launch Fatal error occurred (5): A device attached to the systeem is not functioning Extracting: windows_natives.jar.lzma to windows_natives.jar." and if I say not now instead it will load and then say "Done Loading" but the loading bar isn't full and it just stays that way. --Jason
  • My hunch (and my hunches have recently tended to be pretty accurate) is that you need to update your Java _and_ your video device driver. I have no specific technical know-how to back this up except a general knowledge that driver problems can fool software into thinking you have a hardware problem. My other hunch is that you're having an analogous problem with DirectX games (which Minecraft is not) -- Featherwinglove 01:18, 1 September 2012 (UTC)

[X] If you log on the demo version, then log out, then log in with the wrong password, it lets you play offline-mode.Minecraft5025 14:20, 23 August 2012 (UTC)

[X] ArrayIndexOutOfBoundsException when displaying keyboard movement commands help screen.

  • This can be reproduced by setting the "move forward" key to a mouse button. For example: key_key.forward:-99. org.lwjgl.input.Keyboard.getKeyName will then throw. I attempted a workaround by modifying the lwjgl source for the getKeyName, sadly I cannot get that project to compile with jdk6 because it appears to depend on a deprecated "apt" (Annotation Processing Tool) that was only distributed with jdk5.

[X] Cobblestone generator makes obsidian from the lava. I had a working cobblestone generator, then I made an infinite watersource from it and later made it into a cobblestone generator again. But then the lava became obsidian, without any reason. An image of how it looks: It was all just like this, except the obsidian. That was a lava block, as mentioned before. --DeeTweak 14:06, 23 October 2012 (CET)

[A!] Been going months and I dont know why I hasnt reported this before(New to write here, so correct me if I´m wrong on something), but the story is that when I make something much technically(like that dispensers are connected around a 9x9 square together shoting fireballs with 4 pistons that block the water or make the water go into the 9x9 square with burning sheeps(my latest investigation, lol!)) with wires and repeaters like everywhere, they can be put on ON at first. But then its stuck on ON and I cant get it to OFF, even if I remove the lever or a few repeaters or wires somewhere. The wires and repeaters are still filled with energy from the removed lever. Redstone torches are often not in my works, so they isn´t making any extra energy to the wires and repeaters. Very annoying.. --WildAmanda 14:09, 5 October 2012 (UTC)wildamanda

  • Somewhere in your set-up, there is a path leading from the output of a repeater to the input of that same repeater. This causes that one repeater to power itself even when the original current source is removed, forcing your entire set-up to stay powered. Once you find this "loop", go ahead and remove this bug and my reply entirely. In fact, please take a screenshot and I'll help. If a loop can't be found and your set-up is actually bugged to stay on, we'll keep this here. --Kanegasi C 12:31, 5 October 2012 (UTC)

[X] When water flows over flowing lava in a certain way, instead of turning the lava into blocks, it just stops flowing. Causes the being put out sound effect every so often and when the water first flows, even thought it doesn't. In order to reproduce, check out this image: Replicate that scene without placing the liquids, then place the lava source as shown in the picture, then the water source. May or may not be directional, not tested yet. Tested in 1.3.2 and 1.4.1 pre-release, picture is from the pre-release.

[X] I was holding a Diamond Shovel, and I picked up a brown mushroom. The brown mushroom replaced my Diamond Shovel WITH THAT BROWN MUSHROOM. That totally made me rage.

[X] Whenever a boat collide with something without breaking while it's over flowing water it will act as a ghost: it will travel trough blocks, it will float in midair if nothing is under it and you can't interact or break it. The boat act like that because it's still where it got stuck, but you can't see nor interact with it. Breaking the block close to where it's supposed to be or removing the water will cause the "ghost" to go back where it should be and act normally. I recorded a video but I can't post it. --Gjrud 00:25, 5 October 2012 (UTC)gjrud

[X] While riding a boat over a fixed arrangement of water streams there is inconstancy: sometimes it will work just fine, other times it may look like you got stuck but you are actually still going, sometimes you will get stuck but it looks like you are still going (same as above). I made a video but I can't post it. --Gjrud 00:25, 5 October 2012 (UTC)gjrud

[X] Furnaces will consume more fuel than is necessary if a server is under moderate load.

[!] Redstone is working only in range about 200 block arround the player. Respectively repeaters do not update. Farther redstone is almost not existing and useless. It makes a lot of (big) redstone creations pointless. This issue came with 1.3 update. Mojang, can you please repair it please? Or if this is because of ingame lags, at least make this behavior optional?

[X] [MP] [N] Slabs placed on top of ice will act as ice. I tested this with various different slabs.

  • Actually, in any version of minecraft with ice it behaves like that. Any block that is not one full block (except Soul Sand) with ice directly underneath (even Cake) will behave this way. Trigger hurt 00:25, 2 October 2012 (UTC)

[X] [SMP] When rails are placed on a block with air directly underneath, like so

travel along the track in a cart becomes much more jumpy and laggy, and the player occasionally takes damage, even when sitting stationary in a cart. Placing one more block removes both phenomena, though there is still some jumping along the track. You can easily try to reproduce the damage part of this bug on a short section of suspended rail, as it happens whether you're moving or not, so long as you're sitting in a cart. -- 06:49, 3 September 2012 (UTC)

  • I can confirm this. In an underground mining area, I have a stone wall directly to the left of my minecart path and a stone floor directly beneath the rail. There is no visible lava. However, when the game becomes particularly laggy and when lava can be heard, pain begins inflicting the player. I had a message reading "___ tried to swim in lava" when I was clearly riding my minecart. After I died, my items disappeared and I was unable to retrieve them. -- 17:04, 24 October 2012 (UTC)

[!] The game first began to slow down noticeable, but went to normal speed again. This happens time after time. Then the slowdown increases, until no more than about one frame every 20 seconds was displayed. Input was the same, one every 20 seconds. CPU workload was at 99% (task manager). Gameplay was impossible. Loading that game: same effect. No mods. region fixer tool didn't found a problem. put the grafic options to minimal: same issue. Noticed only in SSP. Oh, forgot one strange notice: sheep-sound seems to work normal during slowdown.--Null Fahrenheit 15:18, 28 August 2012 (UTC)

  • I'm getting this too. Always seems to be in same area for me - something to do with un/loading chunks?
    • If that's the case, try setting the game performance to power-saver, which seems to assign more priority to chunk updating (root.gamerenderer.level.updatechunks.nearchunkssearch).--PlNG 03:05, 25 September 2012 (UTC)

[!] Loading a game, no world appears, but i was falling down very fast about -2000 y-meters or so to the void (saw it in the debug screen F3). Finally i died and the corresponding message appears. No mods used. The issue happens in more than one different sessions. Never been able to play that saved game again. Noticed only in SSP. --Null Fahrenheit 15:04, 28 August 2012 (UTC)

  • Reproduced! I have the same problem, after playing normally, closing minecraft, and starting again, my world seems to be corrupted. The world, i played at last became unplayable, it load very slowly or it loads not, with fallig through the world. It didn't affect to the other worlds.--Locoloco 17:19, 29 August 2012 (UTC)
  • The world doesn't seem to be corrupt. When I play such a world again with a flying and immortal mod (before NOT), I can leave the void and dig to the surface. The player was placed at almost the same location than before falling, but at much lower y-value. so he falls down to the void.--Null Fahrenheit 22:07, 30 September 2012 (UTC)

[X] When a boat crashes into a mob or block at a large speed, the boat will break (if not a mob) and the player will fall through the world into the void. NOTE: this is not a rendering issue, if left alone using mods/godmode to be able to not die in the void, the player's y will decrease until the game crashes at y = -32000000 (known bug due to java integer limits) (tested in SMP only) --AlphaModder3 22:38, 23 August 2012 (UTC)

  • You are using a mod to go to the 32,000,000 co-ord limit. --Blackbird626 16:30, 25 August 2012 (UTC)
  • I think what this person is trying to point out is the after-effect. The chunks never finish loading after this issue occurs. --WizardCM 12:54, 26 August 2012 (UTC)
  • Not modded, You can still tp there using cheats.Minecraft5025 14:15, 27 August 2012 (UTC)
  • Actually, this IS modded. With the new Client-sided commands, although you can teleport to certain coordinates, you cannot teleport after X/Z 30000000, since the world stops generating trees etc. since fake chunks appear. This is only in theory, but I don't think you can teleport under layer 0. --DukeTidierLeader2
    • You can teleport to layer 0, which means falling in the void to your death. However, you can't teleport to a negative y value. HotdogPi Come to my page! 21:41, 15 September 2012 (UTC)

WindowsLinux [!] The lwjgl library shipped with Minecraft often doesn't recognice keys being pressed/released, which results in the player continuously walking in some direction or continuously jumping/sneaking until you press+release that key again. I think this is a major bug, because it causes death to the player by falling down somewhere or falling into lava very often. You can fix this by replacing the lwjgl library with lwjgl 2.6, but every Minecraft update overwrites the lwjgl library again. 08:27, 23 August 2012 (UTC).

Windows [SSP] When walking diagonally into walls to move around it or across a straight wall, it sometimes happens that the player can walk into the wall or get completely stuck, this can kill the player with suffocation damage, flowing water can also push the player into a block and cause suffocation damage.

  • I can confirm this, but it's not just on single player; I've had it happen to me while on a multiplayer server. 13:20, 26 August 2012 (UTC)
  • I've also seen this in 1.3.2 SSP, when walking along walls or near terrain boundaries (water, farmland, or block edges where air is below). I don't start to suffocate very often, but I quite frequently get "stuck" until I tap a movement key one or more times. When I'm next to a wall, I also sometimes have to jump and move repeatedly to get unstuck. It hasn't been lethal, yet, but eventually I'm going to get stuck while fighting a creeper or skeleton. --LoneCenturion
  • I take suffocation damage on multiplayer virtually every time I'm touching flowing water and a wall and am walking towards the wall. --Alex3me0 01:28, 2 October 2012 (UTC)

[!] [MP] Noticeable server lag on connect, sometimes resulting in a disconnect.overflow. Has been tested on two separate VPS' with a fresh run of Minecraft_Server.exe. Performing the same test in 1.2.5, everything is absolutely fine. Copying the newly generated 1.3.2 world to a 1.2.5 server also shows the issue is limited to 1.3. Interestingly this only happens with the Default world type (happens in the Nether too) but not in freshly generated Flatlands worlds. [1] A better example of this in action is with Bukkit and multiple worlds [2]

[X] When I eat food, sometimes it automatically eats another one of that type of food. It doesn't even play the animation, it just makes the sound, and takes my food. This is really annoying as this bug normally happens when I am already nearly full and don't want to eat anymore.

  • Confirmed; if you keep the right mouse button pressed long enough to start eating another piece of food (never seems to happen on the first piece), releasing the button will cancel the animation, but not the actual process of eating. Switching to a different item before the process is completed will, however, successfully cancel eating the food without using it up. This definitely isn't a game-breaking bug, though; downgrading to minor. -- 15:36, 25 August 2012 (UTC)

[!] Similar to 1.3.1, when entering the nether on my MP server the world sometimes fails to load. You and any surrounding mobs just bob up and down in nothingness nigh-endlessly. (Eventually I began to suffocate and upon reconnecting, I found I was at the level of lava, inside the ground.) This is identical to the falling through the world bug in 1.3.1 except you don't die right away, and it gives you more time to disconnect and reconnect. You still might end up BELOW your portal, though, which could land you in lava. --Zair99 19:23, 16 August 2012 (UTC)

  • Similar to this bug and probably the same problem but on our server, you appear 1 block lower than the portal (i.e. You're in it). Most of the time you eventually appear at the correct height but then the portal is activated again and if you don't move quick enough, you get transported back to where you came from. Happened in 1.3.1. --Denney 13:52, 17 August 2012 (UTC)
  • I'm getting a bug where travel between dimensions in general cause problems. Sometimes I end up in random locations, and on occasion I get a "network error" message where the game simply crashes altogether on single player. There still seems to be some sort of portal bug error in place. --Robert Horning 07:13, 18 August 2012 (UTC)
  • In 1.3.1 our server had one overworld portal that when used would lead to a fall through the nether glitch every time you used it. In 1.3.2 every portal will do it, but only occasionally, so you can now fall through the nether or fall through the overworld. Also, once I disconnected during a fall in the overworld, and when I reconnected I was in a cavern fifty blocks below the portal, so there's that. RVernon 15:02, 19 August 2012 (UTC)
  • I recently got a fall-through-the-nether bug... on exiting the gate, I was suspended in darkness, with my Y-coordinate rapidly decreasing. After disconnecting and reconnecting a few times, I was able to recover, ending up properly at the portal. --Mental Mouse 04:10, 27 August 2012 (UTC)
  • And I just got it while exiting the nether by a new gate.... still working on recovery. I clipped some of the error messages... this bit repeats over and over.:

ETA: After a few disconnects and save/loads, I quit falling, and Overworld terrain was visible through the portal glow, but I was trapped in the portal. Another save/load or two, and I was able to move away from the portal, but still surrounded by the portal effect, and after a few more I was able to get back to a normal Overworld. --Mental Mouse 15:08, 3 October 2012 (UTC)

[!] Mobs and other players sometimes glitch in the ground making them black or not visible at all. QuAd205(T|C) 14:05, 17 August 2012 (UTC)

  • I can confirm this. Mostly seen with villagers and iron golems. --Denney 05:46, 19 August 2012 (UTC)
  • Not sure if this is the same bug; but while transporting villagers with a mine-cart the villagers would suddenly disappear. The cart responded exactly like an empty cart (same inertia/momentum), after a seemingly random period of time the villager would suddenly reappear in the mine-cart as if nothing had happened. Another time this glitch occurred I accidentally entered the mine-cart while trying to place some rail under the cart that "held" the villager. I assumed the villager lost and continued to my base with another villager who was in front of the previously mentioned villager. When I returned to collect my rails, the lost villager was standing next to the spot where I had entered the cart. (this occurred while running a vanilla version of Minecraft 1.3.2) --Dvb9096 05:05, 22 August 2012 (UTC)

[!] I seem to be taking fall damage from falls from 2-block high ledges and even from just jumpingin the prerelease-- 21:26, 14 August 2012 (UTC)

  • It does seem that falling damage has been tweaked a bit. I need to fall from a 3 block height (or jump from 2 block height) to take damage. Places that used to leave the player with a heart or two now kill you. --Denney 13:45, 17 August 2012 (UTC)
  • Major. Died like that in Hardcore. --Blackbird626 22:10, 18 August 2012 (UTC)
  • Agreed, on my MP server I sometimes take damage from 2 blocks high. A 4 block fall took off 2 hearts. I nearly died going down a mountain before I figured out what was going on! In SP it was a little better, with a 4 block fall doing 1/2 heart, and a 7 block fall doing 2.5. --Zair99 22:57, 19 August 2012 (UTC)
  • Same here, i am getting hurt at 3 block drops in some servers. SP 3 block drops don't hurt me as often, but still on occasion do. –Preceding unsigned comment was added by (Talk|Contribs) . Please sign your posts with ~~~~
  • Tested and confirmed on separate setups, players, computers, and servers. Single player is consistent with the 2 blocks per heart minus 3 equation, but multiplayer is not consistent. Different healths were obtained using a control of 20 blocks fall distance, ranging from 4 hearts left to death. My assumption is with all the server-side controls of the game environment in this version, it seems latency affects distance measurements far too much. There are also plenty of reports that sound lags when placing objects and footsteps, and I personally experience massive jumpy lag when riding a minecart, even though my latency is above average for a real-time online game. --Kanegasi C 04:36, 23 August 2012 (UTC)
  • Very annoying bug. Have died from a 2-block-fall with full health. Worldofminecraft 20:22, 27 August 2012 (UTC)
  • Reproduction directions: Build a short pyramid with a 2x2 top, 4x4 mid layer, and the ground. Jump off on a diagonal, land dead center in a block. No damage. Jump off, land near a crack, break your mother's back. Strange. I went to test some variables, and I can no longer reproduce the issue, even though I was consistently hurting myself before I changed the terrain. Only notable thing is the point I chose crossed chunks.--PlNG 00:02, 1 September 2012 (UTC)
  • I take half a heart when falling 3 blocks while recording and my frame-rate is capped at 30fps, but I don't take any damage when I'm not recording and running at a frame-rate of 200. 10:21, 8 September 2012 (UTC)

Being near the lava hurts you, like I am on the middle row.--Blackbird626 16:34, 25 August 2012 (UTC)

  • Another scenario (probably the same bug) exists in 1.3.2 and 12w36a SMP

1 have a 3 blocks large floor of cobblestone in a nether lava lake with rails on it. I've put glass blocks above rails to prevent zombies pigmen to spawn there and cobblestone walls + Ceiling to protect me from ghasts. I sometimes get on fire while riding the wagon. Can lag misplace the player and put him in lava? The floor cobblestone blocks have been put there by replacing lava blocks. Could those blocks have kept a property that make them burn the player?

--sfisabbt 08:40, September 11, 2012 (UTC).

  • Confirmed 24.9.2012. Can occur even when player is around 4 blocks high from any lava. Also occurs usually only at high lagspikes, propably due chunkload.

[!] [MP] The invisible blocks phenomenon reappeared, especially when digging down a pillar. The view is shaking until leaving and reentering the game. --Kumasasa 20:55, 16 August 2012 (UTC)

  • This happens very consistently when digging down on a dirt pillar, about a 20-30% chance per block you try to dig. This is on vanilla MP, linux server, OSX client. There are no errors in the server log. --RogerWilco2
  • This also happens when pillar jumping in Single player survival mode. Digging below you leaves you suspended above a ~ 6 block empty space but doesn't stop the shaking mode. You can force your way off the virtual pillar top by holding a direction key a long time, then gameplay returns to normal but you fall to your death. If you dig one block at a time down from the pillar top, and let the graphics settle, its less likely to happen. It happens with any pillar block, netherrock, cobble, etc. --Mikejo28 10:02, 28 August 2012 (UTC)
  • (Merged duplicate --Kumasasa 23:38, 18 August 2012 (UTC)) The 'sinking into blocks and getting stuck' bug seems to be getting stranger. I'd pillared up into the sky on leaf blocks, got jammed, tried both jumping and removing the blocks around me, and ended up marooned in mid-air. Plenty of time to look around, take a screenshot, etc. The other consistent symptom I see is that while stuck you vibrate up and down by about 1/16 of a block several times a second. Pausing and resuming, and even quitting and reloading the world (but I didn't quit the Miecraft app itself) did not fix matters. However, after the quit and reload a block that I'd destroyed reappeared, and when I rebroke that I fell out of the trap and could resume my game. -- 22:07, 18 August 2012 (UTC)
  • (Merged duplicate --Kumasasa 17:53, 20 August 2012 (UTC)) Since the upgrade to 1.3.2 I have had this problem twice. Never before then, so I assume it has something to do with the upgrade. (In fact, if I remember right, the first time this happen was the very first time I logged on after 1.3.2 was installed.) As soon as I log into single player and get to point of gameplay, the game is immediately trembling vertically. It is as though I am constantly trying to jump when there is no space available to do so, only it also prevents me from being able to move around. (I can turn within a single point, but cannot leave that point.) The first time this happened, I was eventually able to get my Player to enter the bed, and when it got up the problem went away. The second time, there is no bed available, and it just keeps on trembling. Was occassionally able to place blocks, but could not remove them. If I log of and log back on, nothing changes. It seems as though gameplay is permanently disabled until I can get this problem resolved at this point. –Preceding unsigned comment was added by (Talk|Contribs) . Please sign your posts with ~~~~
  • The digging down a pillar bug happens some of the time even if I wait a couple of seconds between blocks. A reliable way (at least for me) to avoid it is to move a little bit after breaking each block. So essentially: sneak, dig a block, move back a bit, dig a block, move forth a bit, etc. Masa 12:33, 6 September 2012 (UTC)
  • The reason this happens is because the client thinks you broke the block, but the server thinks not. Therefor, to other players you would appear stuck on a block, but to you would appear floating and glitched.
  • I can confirm this, this happens in MP and SMP. --hultberg 20:02, 20.09.2012 (North European Time)
  • Similar problem when mining Netherrack with Efficiency-Pickaxe. The blocks seem to break to fast and sometimes the server does not recognize one as broken. Also had problems with invisible fire or fire that cannot be put out. Schevv 10:53, 28 September 2012 (UTC)
  • Even worse: Digging snow blocks with a diamond shovel. Also, in creative mode, breaking around 10 blocks/sec will make this glitch annoying. --Blackbird626 22:20, 19 October 2012 (UTC)

[X] Building a water tram (or EATS) in which the boat runs on ice caused the boat to become glitched, so that it will move only in a straight line, going through blocks, and floating through air until it slows to a stop (after it leaves the water streams) upon stopping, it will warp back to the start of the track and continue until you break it the start of its loop. After it touches the ice in every iteration, it cannot be left or right clicked. Just after it leaves the end of the track, it will drip water, and won't collide with the player until it dries off.

[X] [Cr] When flying over great distances in creative mode, you obtain enough inertia to be propelled very far. How to reproduce: enter flying mode and fly 1000 metres in a certain direction (e.g. f:0). When you've reached the 1000 metre mark, let go of the forward key. You should keep flying for another 700 metres before you come to a stop.

[X] When I was playing creative mode, there was a lightning storm, and the fire from it never burned down. This is on Windows Vista. I really don't know what category to place this into. Cookie FONster 13:59, 17 August 2012 (UTC)

  • I have witnessed this twice in 1.3.1 and once in 1.3.2 in SSP (which is strange in itself given I've only witnessed one lightning storm in several hundred hours of gameplay since lightning was introduced -- is lightning more frequent now?). The fire persists even after logging out or moving far enough away for the chunk containing the fire to be unloaded; however, the fire will be gone when logging out with the chunk unloaded then returning to that area. --Be unreasonable. 13:20, 18 August 2012 (UTC)
  • I saw this in 1.3.1 SMP (I had also never seen a lightning strike ground before). I stepped into the fire and the flames that indicate that you are burning appeared on the screen. The fire wasn't really there so I didn't receive any damage though. Kp 22:10, 18 August 2012 (UTC)
  • Yep, I'll confirm this for v1.3.1 and v1.3.2. Fire persists for quite a while. Walking into it indicates you're on fire but doesn't do any damage. --Denney 05:37, 19 August 2012 (UTC)
  • I have just encountered persistent fire one block above the ground after a lightning storm. This was in an open area where there was no tree that might have burned down. Also, the fire persisted through half a day and night cycle of rain and there should be a better balance to allow fire from lightning but still have rain put out non-brimstone fires. --KADC - "Be unreasonable." 19:51, 1 September 2012 (UTC)

[X] When filling up water/milk/lava in stacked buckets, it will usually result in an extra duplicate of the filled bucket. This might affect gameplay, since they can exploit this to cheat. Tested with 2 stacked buckets, and filled them with water, got 3 water buckets.

  • Visual bug only, the extra bucket is not actually there. Happens with bottles and bowls, too. Downgraded to minor, move to annoyances if not even that. 00:32, 20 August 2012 (UTC)
  • I've also had the reverse happen: filling a stack of buckets seems to not return as much, but placing anything in the inventory slots it would auto-fill into makes all the missing buckets reappear. George Mallory 20:31, 22 September 2012 (UTC)

[X] Got into a boat which was slightly on land when I got in. Set off slowly, but did not speed up. After about 30 blocks of slow progress, got out of the boat and teleported 30 blocks back to where I'd got on, with the boat 30m away at the point where I'd given up. Simlar to the EATS road boat glitch also, but not quite the same. I could turn, and apart from the slow, slightly jerky progress, everythinf seemed to be working, until I got out. -- 10:39, 20 August 2012 (UTC)

[!] (first time this happened to me)It was the second time I tried playing since the new upate (1.3.2) and when the skin reverted to Steve, I just went through to change back the skin. Re-opened the survival world to find my Kain skin, but I cannot move (not even my cursor), and the game acts either like I'm repeatedly pressing sneak or jump and I almost fall through the floor of my house several times. This only happens on that world. Tried meerly quitting and re-running the game, but it only made the skin revert back to Steve. The game has not crashed, but I cannot play that world. I never had a problem this major before. --DracoFamiliar 4;01PM, 8/22/2012 (UTC)

[X] Also, a more serious lag issue occurs when you are mining a block, then if you suddenly switch tools or switch to/from hands when mining, you will clearly see the block lag, seeing it reappear for a second or two, then dropping as a drop. This is a serious slow factor when switching your tool to improve efficiency while maintaining durability on upper-grade tools, on things like wood or melons. --Wormy14 12:19, 24 August 2012 (UTC)

My last 1.3.1 Bug Report Stated that it was almost impossible for me to retrieve items from my chests.Well 1.3.2 helped a little.The % chance of them messing up and not letting me get items from them has decreased. Nice work Mojang,but the bug isn't gone quite yet. It still acts horribly in lag. The best way to explain this is when you try to use chest Example: taking stuff in/out it will put it in/out of your inventory/chest.Basically ignoring EVERYTHING you do to a chest.This bug strangely does not effect other GUI items(I might be wrong,but I haven't seen gui lag except for chest.)

[!] [SSP] Worlds are not being properly saved and/or recalled by the game. Similar to a bug listed in the 1.3.1 wiki, with great frequency I can destroy and place blocks, then save and quit the game, only to log back in and find that the blocks I destroyed have been replaced and anything I built has been undone. It is as if when I log in the game is loading a save from 5 minutes before I hit the "save and quit" option. This is especially annoying with chests. If a chest happens to be lost in this fashion then everything in the chest is lost as well. This bug is especially frustrating. I have been able to replicate this bug in both SSP and CSP, but not in SMP, yet. --hogzfan

  • I am having the exact same problems, it is incredibly frustrating. I no longer have the patience to play the game. I've lost lots of diamonds, entire rooms to my structures, and most recently 30+ levels because I log back in and I'm inside a block that re spawned. --FranticAudi
  • I just experienced this problem. An area that I mined in the previous session reverted to how it was before I mined it; however, this appears to be limited to that specific chunk (hopefully) as other areas saved normally. --KADC - "Be unreasonable." 19:51, 1 September 2012 (UTC)
  • I am getting the same problem since switching to 1.3.2, it is as if all world changes are being cached in memory only and are never saved to disk when I choose save & quit. I am using WinXP with Java 7 and no mods. As above, player location and inventory is saved and reloaded but not world changes. -- 20:38, 4 September 2012 (UTC) (TheOriginalSteve)
  • UPDATE: The solution for Windows XP has been posted on the Minecraft forums: right-click the launcher icon on your desktop, choose Properties from the menu, select the Compatibility tab and check the Compatibility mode: "Run this program in compatibility mode for: Windows 95". Click OK to save this change. This will also work if you use Magic Launcher as your main launcher.

  • Same problems here, including but not limited to: (1)Items randomly disappear both from chests and the inventory. (2)Mobs disappear when saving and reloading the game. (3)Player death not saved correctly - closing minecraft when dead, then loading may sometimes resurrect you. (4)Player location not saved accurately in case of death.

  • NajMasta here and again, I'm having that same issue as I did in 1.3.1. The issue above is affecting every single world I have and I have reproduced multiple times. The fix stated above isn't really a fix. Its a work around. We shouldn't have to go through the whole compatibility process because it should work on our computers as is.--NajMasta 00:36, 3 October 2012 (UTC)

[!] Drowning without an oxygen bar / bubbles appearing. Here's a world save since I encountered this in a complicated setup. Parked right in the spot. Not sure if this is a reintroduced bug related to drowning under a block and moving water. --PlNG 02:19, 5 September 2012 (UTC)

[X] Boats will often break if they collide with more than one lily pad at once. --Wormy14 10:46, 25 August 2012 (UTC)

[X] [SP] In SSP, sometimes blocks act as if a lag was occurring. Dragomok 19:30, 25th August 2012 (UTC)

  • When breaking a block while standing on it, it often remains in place (both visually and physically) for about half a second after the breaking animation finishes and the item drops.
  • When placing/removing water with a bucket, the visibility of placed/removed block "blinks" between updates.
  • Placing rail results in it appearing oriented from left to right and adjusting its orientation to match surrounding rails a split second later.

[X] Spawn locations on servers have blocks protected from any changes (mining, placing blocks...). I know it has it's purpose on public servers but on private servers it's only annoying. There should be ability to set this behavior True/False in server settings. "spawn-protection" property is missing in server properties file. Adding it in doesn't help.

  • It would certainly be really helpful if you got stronger feedback on where the 'forbidden' zone is. A 'clunk' noise instead of the normal digging or block-placing sound, for example. -- 23:10, 17 August 2012 (UTC)
  • spawn-protection do this sound familiar? Try it. If that doesn't work, then there truly is bug. -- 06:13, 18 August 2012 (UTC)
  • I'm sorry but what do you mean by spawn-protection? I don't see anything like that in Properties file and when I add it (spawn-protection=false), nothing happens. It also isn't listed in available commands list. Workaround for this is /op command which, unfortunately, has a side effect of allowing cheats for op-ed players.
  • Well seems like when they reworked whole property system, they forgot about spawn-protection. There used to be property with that name. I would move this to bugs. -- 17:32, 19 August 2012 (UTC)
  • OK. I moved this to bugs.
  • The spawn-protection property only applies if you have Minecraft Forge Modloader. It actually does not exist without Forge.

[!] Migrated accounts get a bad login error when they try to connect -- 16:55, 26 August 2012 (UTC)

[X] 1.3.2: Spamming TNT on a redstone torch while above Y = 88 will cause blocks almost at the bottom of the TNT pit to pretend that they are there. The blocks are solid and will disappear once they are given an update. 05:25, 27 August 2012 (UTC)

[!] If you kill a pig with fire, you will obtain Cooked Porkchop, but if your killing a chicken or a cow with fire you will obtain raw meat, raw chicken, uncooked as previously

[!] Minecarts sometimes become impossible to exit by right-clicking. Encountered both in SSP and SMP. Right-clicking the minecart you are sitting in does nothing, hitting it with a sword or any other melee attack only affects the block below the minecart. The only way to get out is to shoot the minecart with a bow, which destroys it and frees you. Since this breaks the minecart, it makes any advanced station designs impossible, and thus I am marking this as major. 14:57, 7 September 2012 (UTC)

[X] Sprint Jumping off a 1.5 tall ledge will cause a half-heart of fall damage. This has only been tested with fences and fence gates, not a block and half slab.

[X] Ordinary users cannot _INTERACT_ with blocks near spawn -- fence gates that give you a safe area, chests with supplies, etc -- cannot close the gates, cannot get supplies out the chests, etc.

It's one thing to disable block alteration/breaking. But opening/closing doors/gates/chests? --Keybounce 18:31, 9 September 2012 (UTC)

[X] Sometimes keys get "stuck". For example, I was running up to a creeper to hit it and knock it back but when I let go of the W key I kept moving forward and right into the creeper detonation radius. It has happened with other keys too: space, A and D keys. Pressing the key again and letting go makes it "unstuck" again. I am on Mac (reportedly happens on Windows 64bit too) and this happens in SSP (I don't know about multiplayer, but my guess is that it happens there too since this seems like a lag-related bug, considering that it never happened to me before 1.3, the update which made SSP run on a local server).

  • I have experienced this same error in SSP and SMP with the WASD and Space keys and left click when mining. --Zallo03 22:45, 21 September 2012 (UTC)

[X] Mobs take fall damage when landing in 1-deep water after being ejected from a dispenser (using spawn eggs) from a 6-block height. Since it normally takes at least an 11-long drop in order to take fall damage when landing in 1-deep water this is a bug. Here is a screenshot demonstration: Setup Result. This bug has existed since at least 1.2.5.

[X] Mobs and players take 1 (Half Heart.svg) half-heart of fall damage when falling into 1-deep water from a 4-block elevated ledge without jumping. If you or the mob jump from the ledge instead of walking or being pushed off of it, no fall damage is taken! Image explanation: Setup Result. This bug has existed since at least 1.2.5. [X] occassionaly in SSP and SMP when playing my veiw will go straight up and start spinning fast. not sure if game bug or just my computer. --Zallo03 22:45, 21 September 2012 (UTC) [X] In SSP and SMP when run jumping sometimes i will receive a heart of damage for no reason. This occurs particularly, but not exclusively, after jumping to a block level lower. I have been able to recreate this bug multiple times. --Zallo03 22:45, 21 September 2012 (UTC) [X] On singleplayer if you play in a creative world and you equip any armor then swich to survival via cheat (/gamemode 0), open your inventory and click on any part of your equipped armor, all your armor will vanish. (found by NemockZans)

This bug also appears frequently when entering/departing the Nether in singleplayer while in creative mode. It is very annoying, and very frequent.

[X] Multiple zombies attempting to break down a door may cause the door's top half block to show the breaking block animation (unmoving cracks/not changing, and staying in the last frame) permanently at that block position. Placing blocks in that position/breaking blocks does not cause the glitch to disappear as the newly placed blocks also display the block breaking frame. Even without a block in the position, the cracks still show on the air block. --M0rphzone 02:53, 4 September 2012 (UTC)

[X] Should player fall into Void while in a boat, and then start flying before the damaging -64, this will happen:

  • Player won't die aside from /kill
  • Stops working after dying. Can be redone, though.
  • Mobs can "lag" - they won't move and can't be hit. They still can fall, though. Not sure about fall damage.
  • Boat will disappear (obviously) and player will not be able to enter another.

In Survival and Adventure (should player use commands to change game's mode into one of these), also these things happen:

  • Player receives 1 (Half Heart.svg) (half of heart) of damage while placing/destroying blocks and while inside of a mob (no idea how often it deals damage, but it does in at least these conditions). First death said it was by suffocation, second said I got killed by Slime. No idea if it is random.
  • Player can't be damaged aside from /kill and and the aforementioned damage.
  • For a reason, after entering sheep and taking some damage, the damage stopped. Then I jumped into Void and killed myself at -64. Happened only once so far, though.

Seems to not work if player first starts to fly in boat and then falls. I could do it only with first falling, then flying (but feel free to check if it's possible to do it the other way). If player doesn't receive any damage after -64, that means glitch is working.

Tested on Windows XP Service Pack 3, non-modded Minecraft 1.3.2. Glitch can take a while to reproduce as at the first I could do in few tries, but then I couldn't for a while (I started receiving damage on -64) and finally I managed to redo it (no damage after -64).

Glitch seems to not work with Minecart, can't reproduce with pig as riding it is too difficult.

[X] [SMP] The taking damage bug (if water pushes you into a corner) is still not fixed in multiplayer, tested on bukkit server and vanilla. Trigger hurt 13:39, 27 September 2012 (UTC)

[X] After travelling in a minecart far enough for the chunk containing the start point to be unloaded, momentum is maintained on flat tracks without additional powered rails until the cart is stopped due to running out of tracks, exiting the minecart, etc. -- KADC - "Be unreasonable." 21:20, 1 October 2012 (UTC)

  • This was only tested to slightly over 100 blocks (the maximum travel distance should be 80 blocks with noticeable slow-down after 40 blocks) so I do not know if there is an ultimate limit to the distance the minecart can be ridden in this manner. -- KADC - "Be unreasonable." 21:20, 1 October 2012 (UTC)

[X] Zombie attacks (a siege would require them surrounding the village) occurred every night for five consecutive nights until I moved far enough away for the chunks containing the village to be unloaded. I originally thought the recurrence was caused by not leaving the 40 block village limit but this proved not to be the case and only unloading the village ended the attacks. -- KADC - "Be unreasonable." 21:20, 1 October 2012 (UTC)

[!] If you exit the world during falling then when you open the world you will not get falling damage. This works on SSP and SMP. Strange bug, this can be used to survive long falls, however (i think) this is not a valid and intented action.. 14:43, 2 October 2012 (UTC)

[X] A bug that used to be only in multiplayer but is now in singleplayer due to the 1.3 client-server architecture change: The spherical area that the player has to be in for monster spawners to become active is shifted skywards by a distance of two blocks. The monster spawner's glowing particle effects are tied to the correct sphere, so from certain positions it can be confusing to see the spawner apparently active but never spawning any mobs.

[X] If you destroy a furnace after smelting Iron or Gold, you get no experience from the furnace but you get the smelted iron or gold. --User:zeeteeess


[A!] The distribution table for the chance to get the Silk Touch enchantment should be modified so it is more likely at lower enchantment levels and less likely at higher levels because:

a) its primarily use is decorative which provides little gameplay advantage which warrants it being easier to create
b) it's useless for axes because all wooden blocks and items always yield the same block/item anyway
c) it's useless for shovels except to collect grass
e) it's detrimental to pickaxes as a resource mining tool as it effectively causes a lower yield of usable resources because any coal, redstone, or lapis blocks must then be re-placed by the player and re-mined with a pickaxe without Silk Touch and therefore should be a "cheaper" enchantment
f) it too often takes up an enchantment "slot" that might otherwise go to a more useful enchantment when creating high-level tools

(ex. Patiently levelling up to create a level 30 enchanted diamond pickaxe then getting Silk Touch, thus rendering it useless for mining ores regardless of what other enchantments it may have, is very frustrating -- having it happen twice in a row is maddening.) -- KADC - "Be unreasonable." 21:26, 5 September 2012 (UTC)

  • Alternate solution could be wearing a pumpkin or holding an Eye-of-Ender when enchanting to allow the player to see what enchantments will be added. -- KADC - "Be unreasonable." 21:26, 5 September 2012 (UTC)

[A] When breaking a block that the player is currently standing on, the cracks appear to flicker between visible and non-visible. This is vanilla Minecraft 1.3.2 -- 14:30, 25 August 2012 (UTC)

[A] [SMP] Right clicking on a chest twice in rapid succession causes the chest to do strange things while you are still accessing its contents- Just an artifact, I suppose. The chest will sometimes stay open, will sometimes close behind the GUI and remain closed, and sometimes will stay open, even after the GUI is closed, and then never open/close again. Multiplayer users agree with chest's position- Only fix is to destroy the chest, but it has no affect on gameplay- Just a visual thing. 02:49, 20 August 2012 (UTC)

[A!] Block update lag mouse input issues still persist, with multiple place, multiple switch/door/gate frobs, and even multiple breaks happening on a regular basis. I'm not sure why block update lag spikes are getting worse, but it might just be time for me to get a better system. Nevertheless, I was, and still am hoping to see one update per frame when I let go of my mouse button before the frame in which I pressed it is over. Griefing my own SSP game like Team Avolition was pretty funny, but it gets old fast! -- Featherwinglove 12:53, 18 August 2012 (UTC)

  • Update: Starting with version 1.3.1, I began to experience block placements on subsequent frames, and this is how most triples occur (A "triple" is a single commanded block placement happening on one frame followed by two uncommanded block placements on the next frame.) If I am placing a block where two possible subsequent placements may occur without moving the crosshair, the commanded placement appears on one frame, which lag spikes for about a quarter of a second, by the end of which I have released the RMB. After this frame, the two subsequent uncommanded placements appear about half a second after I have released the RMB, on the same frame and with a single placement sound audible. There are also many occasions where the lag spike does occur, but unintended placements do not; almost all of this correct behaviour occurs with placements at eye level, while unintended placements are usually made after an intended placement above or below eye level. Unintended placements after a deliberate placement above eye level usually go into eye level; this is an effect of my branch closure technique, so I believe that the likelihood of unintended placements depend on the relative altitude of the commanded placement. I have verified this eye level correlation by often commanding placements at three metres distance so that the two subsequent uncommanded placements have room between the commanded displacement and the character. I have also noticed that switching off smooth lighting makes the lag spike and unintended torch placements less severe, but I don't think this is relevant. Turning off smooth lighting has had no effect on the occurrence or duration of lag spikes and uncommanded placements associated with zero-luminance blocks like brick and cobblestone. I have noticed that block update lag spikes and uncommanded placements happen much more often at void fog altitudes (below Y=16). Whether this is due to void fog or proximity to lava, I'm not sure. -- Featherwinglove 04:28, 19 August 2012 (UTC)

[A!] (Yes, this is at least as important as a minor bug). Just tested a 1.3.1 client connecting to a 1.3.2 server. The initial load of the screen and low responsive-ness at start got me blasted by a creeper before I knew what happened.

  • In single-player, a non-responsive game slows down everyone -- even the mobs -- and you don't get blind-sided.
  • In normal play, you can see areas where there are lots of mobs, and if you pay attention, you can get warning sounds of mobs before you reach them.
  • But when logging in, when there is nothing you can do? That's just cheap. --Keybounce 14:32, 15 August 2012 (UTC)
  • Semi Confirmed, I played on my friend's PVP server, FlameZone PVP, which was dated to 1.3.1 but I and some other people who had disconnected updated to 1.3.2, and were still able to connect because of how minor the updates were.

[A] [MOD] If a 1.3.2 client connects to a 1.3.1 server, they cannot drown. If I had proof I could show you but you can very well test it. Untested on vanilla server, only on Bukkit server.

  • Tested with vanilla, drowned like normal. I dont know why mojang allowed cross version connecting (for these versions at least). Version confirmation on [edit]. -- 05:46, 18 August 2012 (UTC)
  • I believe the reason for cross connection to servers was intended for versions without major additions, such as 1.3.2 compared to 1.3.1, because even though lots of fixes were made, no actual item or block updates were added. In addition, most 1.2.4 mods worked with 1.2.5 just as well, and also were allowed to connect from 1.2.5 to 1.2.4. Tested vanilla, not Bukkit.
  • Tested on a Bukkit server, I had no trouble drowning. 07:49, 27 August 2012 (UTC)

[A] You can sneak off cactus. (This was patched but now it happens again)

  • Correction, you can sneak off 1 block high cactus. -- 06:31, 18 August 2012 (UTC)

[A] Signs seem to be blank in some occasions. Possibly chunk-loading related? Had this problem in 1.3.1. too -- 21:26, 14 August 2012 (UTC)

  • I can confirm this on our multi-player server. Happened with 1.3.1. Re-logging sometimes fixes the issue but only for some signs. -- 13:46, 17 August 2012 (UTC)
  • I also have this issue when playing on multi-player servers. I'd personally classify this as more than an annoyance, since signs are used

everywhere. To fix this issue, we've tried deleting my server side player file, and force updating the client side. Force-Updating sometimes will fix the problem for some signs, but only temporarily. -- 22:44, 23 August 2012 (UTC)

  • I don't see how force-updating would help, unless the client keeps getting repeatedly modified, which is almost certainly not the case. I, however, did have this issue before while on a LMP world with my sister. I was the host and could see the signs just fine, but she couldn't. They were eventually replaced and they seemed to work fine again. --Wormy14 12:19, 24 August 2012 (UTC)
  • I too believe that this should be classified as a minor bug, or at least a major annoyance. Signs are quite widespread on some servers. This has never happened to me on single-player, but on multi-player this happened to me on several occasions. Usually for me it is a group of signs that are blank. For example if 20 signs are on a wall, 5 in a row might appear blank, but the rest won't. --Alex3me0 02:07, 2 October 2012 (UTC)

[A] Okay, so I've found two bugs that are very irritating: one is when I go into my chest and get something to uses it, when I use the item it decides to go back into the chest I got it from, I loaded the update hoping it'd fix it but nope, still there. The other glitch is the inability to use any block that is interactable (crafting tables, etc.) and makes it impossible to use it without re-logging on. -Aidandrums

  • Can you reproduce this bug on SSP? It may just be your connection to your server. --Innovate.Invent 05:43, 17 August 2012 (UTC)
  • It has happened to me a billion times in my SSP world. Extremely Annoying.-- 21:49, 7 September 2012 (UTC)

[A] Sometimes your skin will revert to default for no apparent reason. Changing your skin and reloading Minecraft doesn't seem to fix this. (noticed too, my red shirt sometimes changes to blue, however changes back again at the next time I log in (certain))

  • I've had this happen too. Haven't yet been able to get my skin back ingame. :/ 18:59, 19 August 2012 (UTC)
  • One reason iv'e found for this: When installing mods with the mcpatcher, I installed the Biospheres mod from Risugami, straight from the forums. After unpatching and repatching, my skin was changed from my custom creeper spy skin back to Steve. Once I went to and rechanged my skin it was changed. This is something that hasn't happened to me before, in 1.3.1 and below my skin was almost always an HL2 zombie from PMC, i only had a couple of instances where my skin was changed, usually it was my fault for an invalid skin and my lack of paying attention.
  • We have vanilla minecraft v 3.2 and our skins are not loading, we figured out that by killing oneself it will reset the character sometimes, however it is not working today and it getting mighty annoing!
  • Connections to the server are not working or failing, sometimes when (on a LMP world) I go out of the range of the chunks loaded by my sibling, my skin reverts or unreverts. However, without relaunching the game, my skin seemingly will never switch from Steve. --Wormy14 12:19, 24 August 2012 (UTC)

[A!] When moving in one direction for a random amount of time, and/or moving and placing/destroying blocks, my movement sticks, and goes in the direction I was moving. This also happens when I jump and when I sneak. It get's really annoying and messes me up a lot, most notably when I'm flying and placing blocks in creative. I believe this does not work on windows 7, but it does happen on windows xp service pack 3. Since this doesn't happen on all computers im not sure how to reproduce.

  • I experience this problem with a computer that's old enough to have shipped with Windows XP but currently runs Windows 7. I suspect that it is slow hardware block update related lag spikes that is causing this. -- Featherwinglove 12:53, 18 August 2012 (UTC)
  • I experience this problem many times. I know that the Wiki records my IP but this is not mine, my real computer runs a quad core processor along with graphics that easily allow for Far Cry 2 to have maximum settings and still no lagging from the game. No idea what far cry 2 is? look it up on google, I guarantee you will find it. either way, my actual system is a real computer, not some crappy laptop or netbook or notebook or whatever. I know it's not just my wireless keyboard, because iv'e played with a wired one after my wireless one needed new AAAs for it. Currently runs Windows XP, plan to get windows 7 installed soon. I've had this glitch rarely in other games too. But i think that this is related to the 1.3 update, because i never had this problem until after some updates in 1.2.5 all the way down to when i got it, back in the first version of the full release. Also never had this problem in snapshots for the 1.3 update.
  • I get this also, and it's got another report below.

[A!] [SMP] I was on an SMP server on a boat when my connection cut out. When I was able to connect again, I was on the bottom of the ocean, dead from drowning. This bug makes ocean travel too hazardous to attempt in SMP.

[!] [MP] Pistons cannot push or pull any rail (Normal, Boost, or detector) blocks, they freeze in their current position and do not move. This is not the case in single player.

  • Tested on a Bukkit 1.3.1 server, I had no problems with sticky or normal pistons pushing/pulling rail. 07:55, 27 August 2012 (UTC)

[!] When a piston is powered by a redstone torch directly below, the piston will extend like usual, but when you remove the torch, the piston will not retract. The piston will not retract EVEN WHEN UPDATED. --Blackbird626 23:08, 23 August 2012 (UTC)

[!] Timing on NOT gates (redstone torches) seems to be broken. I would expect them to act as a one tick inverting repeater but they seem to require a three tick pulse to activate and then only emit a two tick pulse. This effects any circuit that depends on timing, pulse length, or short pulses. A full explanation of the problem can be found here: Video --Innovate.Invent 21:55, 15 August 2012 (UTC)

  • This is major. Upgraded because this is bad behavior of a major feature, Redstone. --Blackbird626 22:03, 18 August 2012 (UTC)

[!] A piston will not retract until the piston ABOVE it retracts. --Blackbird626 22:03, 18 August 2012 (UTC)

[X] A piston will sometimes get stuck in the extended position when it is powered at the same time water (or lava) is pushed into it from behind. (Nothing will cause the piston to retract once it's become stuck; it must be mined and replaced.) There appears to be no discernible pattern to the circumstances under which a piston will get stuck and when it won't—however, for any given piston coordinates, its behavior is consistently replicable in all worlds for a particular compass location of the power source. For example, a piston centered at x=−.5, y=4.5, z=7.5, facing south (0) and having water pushed into it from behind, will get stuck consistently, in all worlds, when both pistons are powered simultaneously from the southeast—but never from the southwest, northeast or northwest. (That is, power must enter the pistons from the east, and approach from the south. A source placed south of the water but which approaches from the north will not result in sticking, nor will adding a delay such that the pistons are not powered simultaneously.)

[X] When you have water with two tripwire hooks above it (Attached to blocks), string in between it, two piston blocks on top of the two blocks holding the tripwire hooks, and two TNT blocks placed in front of the pistons above the string for the tripwire, the TNT will blow up, but will stay in the middle after blowing up. Video --TehDerpness 7:20, 17 August 2012 (UTC)

[N] For the optimal Bookshelves + Enchantment Table settings, placing torches in each corner between the table and Bookshelves reduces the maximum enchantment level. Using 2 row of bookshelves.

  • This is the intended behaviour: Any non-air block (including torches) between the enchantment table and a bookshelf will block the enchantment bonus from that bookshelf. --KADC - "Be unreasonable." 23:06, 24 August 2012 (UTC)

[X] Running into soul sand after riding in a boat for more than a few seconds causes fall damage to the player. Damage type known because it killed me on SMP. 01:57, 19 August 2012 (UTC)

[X] Graphical/block glitch: When you sink below the surface of water, you can see a side texture on the water source blocks just as you go under. -- 18:04, 31 August 2012 (UTC)

[X] if a piston is rapidly pulsing, and there is a hole one block away from the head (it would be diagonal when the head is extended), and you put a rail in front of the head, while there are rails on the sides of the hole, the rail being pushed over the hole may end up dropping as 2 rails, or not dropping at all. this allows for rails to be duplicated and deleted

Sand and Gravel duplicated bug still works in 1.3.2. Here is a video showing how the bug works The server that I play on, has banned pistons from pulling or pushing Sand and gravel to stop players from abusing the Sand and Gravel duplicated bug.

[X] Redstone timing loop issue is still present. Redstone loops still get into invalid states. Loop setup: This is basically an RS-Nor latch modified (with repeaters) to permit a clock signal. Repeater (4) Input signal (set) (redstone wire branch to button) Repeater (4) Inverter (torch) Input signal (reset) (redstone wire branch to switch) Repeater (4) Inverter (torch)

Loop timing: 14 redstone-ticks If the switch is "on/down", then the button cannot put a clock signal into the loop. If the switch is "off/up", then the button can put a 9 redstone-tick pulse into the circuit, and it will then act as a clock.

In 1.2.5 single player, it works perfectly. In 1.2.5 multiplayer AND 12w27a it will lose its timing. Approximately 15 tests; 14 go to lockup (the button side of the rs-nor being on all the time), and one to inaccurate stable timing (on pulse is less than 9 redstone ticks; off pulse is longer than 5.)

This has been repeated in 1.3.2 release. It seems to be less common, but it still happens.

[X] Randomly, wheat blocks may despawn, especially when closer than 2 or further than 5 blocks away. This has even been observed when sneaking, so I'm not just trampling the wheat. Also seems to occasionally happen with oak saplings. This issue makes wheat farming hard. --cgplover

[A] Sometimes slabs that are right-side up will appear upside-down when exiting and coming back in a world.

[A] [MP] You cannot place downfall snow blocks, they also cannot be moved from your inventory or dropped. In 1.2.5 there was a similar glitch with cake blocks. This can be very annoying when you need help from a friend to make some kind of snow somewhere and it needs to be downfall snow. This specific glitch didn't happen in 1.2.5 I believe because it was not meant to be placed, only generated.

  • Tried to place snow fall blocks. They got placed fine. Tested [SSP] [CSP] [CMP] . They can be found on decoration blocks and full snow block can be found on building blocks. Also tested pick block feature, they got picked fine. -- 10:17, 20 August 2012 (UTC)
  • Keep in mind that this only happens in the 1.3.1 multiplayer. tested on bukkit but not vanilla server.

[A] (Not sure if this is the place to put this) When you use "pick block" on a burning furnace, instead of getting a normal furnace you get a burning furnace. although this is kinda cool, it is slightly annoying and should be fixed (sorry if this is not clear)

  • Creative mode's pick-block can return: Double Slabs (43), Burning Furnace (62), Glowing Redstone Ore (74), Wooden Double Slabs (125). IMHO it shouldn't. --mgr 14:01, 20 August 2012 (UTC)

[A] Some blocks have (IMO) assigned wrong tool and/or material type:

  1. Blocks of emerald should require at least iron pickaxe to break (like emerald ores);
  2. Ladders should be classified as "wooden", so axe will be most effective against it (like signs);
  3. Tripwire hooks should be a bit stronger (like buttons and leavers);
  4. Melons should be broken most effective with an axe (like pumpkins).

--mgr 14:56, 20 August 2012 (UTC)

  • Actually the melons make some sense but you are right about the other things. 1.4 will supposedly make efficiency tools not help on blocks that they're not the tool for, though, so axes should be the tool for melon then to actually benefit from a Fortune enchanted axe. 22:07, 21 August 2012 (UTC)
  • One more block: Vines should be broken faster with shears (like leaves). --mgr 11:20, 24 August 2012 (UTC)

[A] [CSP] Sometimes when placing a redstone repeater at eye level right next to you, the redstone repeater appears and disappears. On the F3 menu, I am facing at f:3, if that matters.

[A] Sometimes when placing top-half slabs/upside-down slabs next to each other, after placing it, the placed slab quickly changes to become a regular bottom-half slab. For example when building a bridge with upper-half slabs, this is really dangerous since the sneaking sometimes fails when going up or down slabs. Note that it is not even possible to place such a slab in normal conditions, since there are no adjacent blocks on the lower half of the block. This issue might be related to the player moving while placing the slab(?) Masa 07:38, 9 September 2012 (UTC)

[X] The leaves stacking(v1.3.2): When I got the leaves from a tree with shears and with silk touch tool, i found a bug. The leaves cropped with a shears does not stack with the leaves, cropped with Silk Touch enchanted tools. When I tried to merge those leaves, its just replaced item position.

  • It is a very simple glitch that can easily be fixed: When using silk touch tools on leaves, thanks to an extra set of values, it defaults to use those, which always use the tooltip 'Oak Leaves' since they are values of the default leaves. But shears get their legitimate data values, their true ones, from 1-3. Trigger hurt 14:58, 30 September 2012 (UTC)

[A!] I am making a theme park with villagers and I found a bug with priest villager. I made a small roller coaster with the priest rideing. I closed minecraft for the night and reopened it the next day to find him standing completely still. He would olny get hurt after a few hits, and it seemed his hitbox was shrunk to his head. I was thinking he could be replaced so I killed him and moved on to make sure this was not happening on any others, and I found the train ride I made (also with a priest) had the same bug. I mave a merry-go-round thing (with a white one) and it did not have the bug. I am listing this as a annoyance. also note that about 20 seconds later minecraft crashed. I will put it up if It needs to be.-- 13:14, 9 September 2012 (UTC)

[X] Doors damaged by zombies sometimes (rarely) remain damaged indefinitely until broken and replaced by the player. However, in the indoor zombie raid bug noted below in the mob section, all doors damaged by zombies exhibited this which may indicate this bug is dependant on which way the door opens.

[X] When a tool with the unbreaking enchantment breaks, the icon disappears but the tool remains invisibly in your inventory. The icon will reappear if you select the tool and will have one to three uses remaining, at which point it will "break" (become invisible) again, reappear if clicked on, and have another one to three uses, seemingly indefinitely repeatable (tested at least 10 times with two different tools). updated -- KADC - "Be unreasonable." 20:27, 5 September 2012 (UTC)

[X] When holding a bed (item) and then right click on a chest. It will delete the chest and a random block next to it (without dropping anything). If you keep on right clicking on walls, they will disappear like the chest --MineCrafter0802 1:28, 21 August 2012 (UTC)

  • Cannot reproduce in Single player survival or creative. Right clicking with a bed behaves as expected on chests, both single and double. Make sure you are not "left" clicking with the bed in Creative, or have switched the mouse button mappings: that will destroy blocks. Otherwise, give full details please.
  • I believe that this is actually another bug that I have experienced, when there was an explosion of any sort, the client would not update if it happened when the player was not nearby, and would only update if somebody clicks the block or interact with the damaged site in any way. What you did would have the exact same effect in that scenario, and it would also explain the lack of drops because the items had already despawned. --Wormy14 20:36, 11 September 2012 (UTC)

-Aurelius 00:25, 26 August 2012 (UTC) [X] When you collect items on the ground in creative mode with a full hotbar, you won't see all of them. But if you go in a chest, dispenser, minecart with chest or furnace you will see all of them.

  • Not true as of 1.3.1 or any snapshots for 1.3 that have the new creative inventory, because you can view your survival inventory in creative. That is a lie, unless you were talking about beta (Confirm?) and later until 1.2.5 when creative was made; in that case please report the bug on the version you were aiming for, not the current version.
  • Doesn't this make sense? Before the survival inventory in creative, you couldn't see anything aside your hotbar, so it would collect into the rest of the inventory, just like in survival mode. Makes sense to me. 17:55, 7 September 2012 (UTC)

[SMP] On multiplayer, death sometimes does not drop all items properly, either dropping them inside of a block or deleting them entirely. Items dropped from death are also frequently to players in the area until they relog. --Swampert rox 20:55, 19 August 2012 (UTC)

[A] The chest's lock in storage minecart is often changing sides while the minecart is moving. This is caused by the fact that the lock is on the front when the minecart is moving horizontally and on the bottom-most side when it's going up- or downhill. Dragomok 21:51, 25 August 2012 (UTC)

[A] I have a problem: When I try to shoot an arrow,it instantly loses all momentum and falls straight down no matter what.This happened after I shot an arrow onto a pressure plate.

  • Experienced this too. It's a client glitch, only visible to you or whoever shoots. The arrow is actually traveling, and if you get to where the arrow lands it will update and the arrow will zoom really quickly to the spot.

[A] While helmets are more expensive and generally provide the same defense than boots, they have less durability than boots, thus, their greater cost does not give a real benefit over boots

  • I agree this is a big imbalance. My recommendation for fixing it is to have helmets give protection against fall damage as default (i.e. without Feather Falling enchantment). Not only would this redress the balance, but it is consistent with reality, while having a Minecraft-like attitude because it is impossible to land on your head in game. -- Featherwinglove 14:15, 18 August 2012 (UTC) (P.S.: Still, I like my boots!)
  • Actually, the recipe for helmets take 1 more resource than the boots one, therefore the durability of helmets should be increased. We could make a proportion to discover how much.

[A] Recipe for books was changed without compensation for the now rarer component of leather. The nature of this drop renders mass production of bookshelves for large scale library builds impossible.

[A!] In creative, even if your inventory is full you can collect items, but they are deleted. Unsure if this is an intended behavior, but it is awfully annoying since on my bukkit multiplayer server one of my friends did something that made 2 explosions in my log cabin, and I don't have the survival resources to fix it, but before I went to creative I thought about this and then just ragequit. I'll probably go back to it later, but it would be helpful if in creative you didn't collect items if your survival inventory is full. This applies to all versions with creative mode available, and is really annoying for situations like that, since a good 3/4 of my 12 chests were full, and were smashed. If only you could have 2 linkable chests instead of ender chests, then I could just have a spare chest somewhere else.

  • I have reproduced this problem in single player vanilla 1.3.2 with same seed and same coordinates. It looks like the old surface terrain bug from Beta where x and z axis was flipped when calculating which surface block to use for some of the chunks at the border between two biome types. I also tested this in Beta 1.8.1 and although the terrain and biomes are different from 1.3.2, the terrain error exists at the same chunk boundaries. I remember some of these x and z "axis flip" bugs were fixed, but some users kept reporting the bug still existed in some seeds and locations. -Aurelius 23:22, 25 August 2012 (UTC)

[!] [SP] [LMP] MC 1.3.2 - Apparently there was once a bug where you could ride a saddled pig in a minecart to go really fast. That doesn't work in MC 1.3.2, but instead there's a whole different bug:

After riding a saddled pig in the minecart some distance, you fall off the pig onto the tracks, and the pig keeps on going without you. Then if you look behind you... the world is disappearing! If you stand still the world disappears under you and you fall. (I've only seen this in Creative mode so I don't know if you die, if you fall into the void.)

In Creative mode you can quickly start flying and chase behind the disappearing world trying to catch up with it. You can catch up but never actually cross over the edge to the inside.

If/when the pig eventually stops in the minecart the world stays fixated on the pig. You can fly away from the pig and down around the outside edge of the world on all four sides around the pig.

If you exit the game and re-enter, you reappear... in the minecart. The pig is not visible but it is also in the minecart. If you destroy the minecart, the pig suddenly appears.

First saw this occur in singleplayer shared on LAN with no other players. It also happens in regular singleplayer.

Recorded example of bug:

-- DMahalko 14:32, 1 October 2012 (UTC)

  • I may have an idea on what this is: Unloading chunks. Okay, so think of it this way: because you are on a pig, and you get kicked off, it still thinks you are riding the pig, and therefor, chunks start unloading. either that or it is client side only, and if someone else were to be on the server, they would see you on the pig. I have no proof, i have no access to a computer able to run minecraft (chromebook) and so i cannot test it.

  • I had this happen before, and I believe I know what caused it. I was also in a LAN world with one other person at the time, and we had traveled a few kilometers and then tamed a couple of wolves to bring home. After we brought them home, we had incidentally hit each other, and it was noted that the wolves that she owned had become aggressive towards me. My wolves were nearby, but I didn't think it was close enough to matter. Apparently, when we came back after a trip, all of our wolves went missing. This was especially annoying because wolves didn't seem to be spawning in any of our nearby forests or taiga (The ones present there disappeared!). I think that they despawned because of the fact that they were "aggressive", and that aggressive wolves despawn after being infuriated. They don't normally despawn, because the enemy is either a mob, which are either killed or despawned, or the enemy is passive, like pigs, which are practically always killed when engaged. A fix would this would be to either make aggressive wolves non-despawnable, or make then revert a good bit before they have to despawn. Also, a more reasonable idea would be to have wolves tagged to an owner or group to reset their hostility over time, and never be able to despawn on their own. --Wormy14 21:03, 14 September 2012 (UTC)

[!!] [MP] Villager populations are not dependent on number of doors nearby; they usually retain low populations no matter how many doors are placed nearby, but on occasion they undergo random population explosions that cause severe lag, can crash servers, and give End of Stream error messages to players that come too close. --Swampert rox 22:04, 26 August 2012 (UTC)

[!] During the last zombie siege, all zombies appeared indoors in the first two floors of two village apartment buildings rather than outside as usual. I've witnessed at least nine sieges and this is the first time this has happened so it's not a consistent bug. -- KADC - "Be unreasonable." 19:56, 5 September 2012 (UTC)

[!] Its the combat delay described below, but it affects every NPC in SSP, animals and monsters. You beat them, but you don't hit them. after half a second or so the beat counts (takes effect), but meanwhile the NPC moves on (away in case of animals, nearer in case of monsters). the moving is often displayed clipped then, but not always. Sometimes the beat takes no effect at all - i guess they moved before beat collision was detected. It seems that the collision timing is fundamentally violated. What have they done to that great game! --Null Fahrenheit 15:54, 28 August 2012 (UTC)

[!] Tamed wolves that are left sitting will randomly teleport to your location, either individually or collectively. I cannot determine a specific trigger. It can occur within a few minutes of having a wolf "sit" or up to an hour later, but it always seems to happen at least once an hour. This can occur both when they are within the loaded chunk radius (assuming the max. radius is still 17x17 chunks around the player) or in an unloaded chunk up to two such radii away, but it does not appear to affect tamed wolves more than three such radii away nor does it happen when they are within the same chunk as the player. To test this I have left three groups of three tamed wolves (two adults and one cub in each group) at three different locations, two roughly 90 blocks away from each other, one group closer than the other to where I was exploring a vast cave system, and one group roughly 900 blocks away. The most distant group never teleported to me so the following refers to the two closer groups. At different times I have had teleport to me (when walking, mining, placing torches or blocks, but interestingly never when I'm in combat): just one cub, just one adult, two adults, all four adults, four adults and one cub, two adults and two cubs, and all six wolves. --Be unreasonable. 19:56, 17 August 2012 (UTC)

  • Cats do the same thing, at least on SMP. To me it seems to be somewhat related to chunk loading, as it always happens when returning to the area of my base (where the cats/dogs are). It will often kill the cats/dogs as my base has many cactuses around it. --RogerWilco2
  • I have just discovered this occurs consistently at a specific locations as well as randomly. When it happens at these specific locations, all wolves within 300 blocks but further than 50 blocks teleport to me but will still be sitting. --KADC - "Be unreasonable." 18:27, 24 August 2012 (UTC)

[!] When tamed wolves "teleport" to keep up with the player (unrelated to the above bug), there does not appear to be a check for solid, unoccupied ground. I have observed them teleporting into mid-air (then falling) and teleporting into lava sources and flowing water. They may also teleport onto the same block as the player or another mod and be immediately forced off which could result in them being pushed over a ledge or into lava. --KADC - "Be unreasonable." 18:27, 24 August 2012 (UTC)

  • Possibly related, a wolf teleported from the ground to 30 blocks directly above it (where I was building a direction marker) and then it immediately fell off for no apparent reason. As I was directly above the wolf and in the same chunk before it teleported, there was no reason for the wolf to teleport up to me in the first place. --Be unreasonable. 20:21, 17 August 2012 (UTC)

[!] There is a problem with the tamed wolf "freeroaming" AI (i.e. When they just wander around, not when they are trying to navigate to the player or a hostile mob.) Wolves will jump off ledges and into lava for no reason. Two wolves randomly teleported to me when I was standing still mining and one ran 10 blocks away into flowing lava and another ran 8 blocks away and jumped off a ledge into a ravine. I have also observed villagers jumping off cliffs which may be related. --KADC - "Be unreasonable." 18:27, 24 August 2012 (UTC)

[!] On the demo, i was killed by a skeleton, i switched to peaceful to get my stuff, then returned to easy. then, all creepers and zombies were frosen visually and physically. All my hits went through them. i trapped them in a hole and buried them in sand, but still nothing. This bug seems to not affect passive mobs, since pigs were normal.

  • I think the creepers and zombies weren't really there. HotdogPi Come to my page! 21:41, 15 September 2012 (UTC)
  • A few minutes after i posted this bug, a skeleton showed up, started shooting me, then the zombies unfroze and ambushed me. (of course i died. damn ambush!)After i respawned, i went to the holes where i buried the glitched creepers in sand. one was gone, no drops. (within despawn radius.) The other one was still buried in sand and frozen.

[!] There seems to be a problem with the tamed wolf "active" pathfinding AI (i.e. when they are following the player). Out of seven wolves (all following me as a result of the random teleporting bug above), five killed themselves from jumping into non-flowing lava or jumping off ledges despite my following a clear and wide path (5 block minimum) that they should have had no problem following. Hostile mobs, on the other hand, have no problem negotiating a safe path the player. --KADC - "Be unreasonable." 18:27, 24 August 2012 (UTC)

[!] There is a problem with zombie, skeleton, and creeper AI where they will sometimes not notice the player. It seems to be more likely if the player is two blocks lower (regardless of there being a navigable path to the player) but this is not consistent. Even if they are facing the player and/or the player attacks them they fail to react. --KADC - "Be unreasonable." 23:33, 24 August 2012 (UTC)

[!] [MP] Since 1.3.1 hostile mobs have stopped spawning on my server. If I restart the server they spawn again normally for a few hours but gradually stop spawning. For example, there were two of us on the server, exploring an unlit stronghold for an hour, over 1000 blocks away from any man-made structures, and we found no mobs, except those from spawners. (Vanilla minecraft, no customisations). This may be related to the above bug, I don't know. 16:06, 23 August 2012 (UTC)

[!] When I transport villagers long distances by mine cart, there professions are lost and they all return to the farmer skin with farmer trade options. I don't know how I would get this on camera, because as soon as a mine cart with a villager leaves a 40 block perimeter of the original village, the villager disappears, which may also be a bug. The villager reappears when the mine cart is broken, but becomes a farmer.

  • I don't see this as a major bug. Downgrading. --Keithicus420 16:24, 17 August 2012 (UTC)
  • Do the available trade items for that villager remain the same or are they reset when the villager becomes a farmer? If you've spent the emeralds to get a villager to have five or six available trades, or even just one very good trade, and they lose it when they enter a minecart, I'd consider that a major bug. --Be unreasonable. 21:14, 17 August 2012 (UTC)
  • Villagers disappearing when leaving the village perimeter is really annoying if transporting lots of villagers by minecarts. For me it means that I have to log out and log back in after every villager to get them visible again. Their professions are not lost however. Masa 07:55, 9 September 2012 (UTC)

[!] Mobs still glitch down through blocks, allowing them to escape XP mob traps that were previously safe. Note that this is not simply a visual glitch, they can interact with the player and the environment. --Anonymous Coward 19:59, 16 August 2012 (UTC)

  • I'm still seeing this too. Notably, when a mob should jump up a block to reach a floor, they often instead wade through the topmost layer of blocks, with only their top half protruding. There may be a connection to the presence of gravel in the "should've jumped" area. Also, my cows and sheep are still walking through fences, though they're hesitant about it -- until they get well clear of the fence, they're likely to drift back. I suspect my chickens are still suffocating each other in crowds, too. --Mental Mouse 23:36, 17 August 2012 (UTC)
  • Upgrading this to major bug because I've been killed several times by spiders that attacked from inside the ground and so could not be attacked back. This bug also occurs with players. --Swampert rox 22:26, 26 August 2012 (UTC)

[X] [MP] There seems to be a mob cap around 40 total hostile & friendly mobs combined. After 40 is reached they stop spawning from what I can tell. Please see my video. -- Kranky 16 August 2012

  • This is a huge problem on my SMP server. The squids spawn constantly and squeeze out all other friendly mobs. It took me two hours to find a cow the other day. And I've now been searching for a sheep for over four hours. But squids? Dozens.
  • Well I recorded another video and I cannot figure out if it is a bug or it is working as intended. I do know it is not a cap of 40 now. It seems that the mobs will only spawn after you leave the chunk for a certain amount of time and then come back. Please see the new video. -- Kranky 22 August 2012
  • Found a fix for the bug. View distance in server properties was set at 6. When I changed it to 10 mobs started respawning again. I downgraded it from major to minor as it is still a bug but there is a work around.

They definitely despawn, it just isn't instantaneous. I've flown up in the air in Creative on servers and the mobs vanished when I got high enough. Note that the chunks have to be loaded with no players within 127 blocks for mobs to despawn. --Swampert rox 22:26, 26 August 2012 (UTC)

[X] [SP] I've just seen a pig moon-walking backwards. :-) Entertaining as it was, I assume that's not supposed to happen. I just wish I'd caught it on video. Presumably a symptom of a mismatch between the position in the server and in the client? -- 22:48, 15 August 2012 (UTC)

[X] Villagers and animals tend to occupy one side of the village/pen. There are houses stuffed with villagers on one side and forever empty on the other side of the village. Almost all animals are in 1 corner of a pen. Both villagers and animals prefer north-west side of their village/pen.

  • My animals seem well spaced within their pens, but the villager issue is definitely happening, with some houses having three times as many villagers inside as there are available blocks of space. If villager AI did a check to see if there are already two villagers occupying the block on the other side of the door then move to the next door instead, this problem might be solved. --KADC - Be unreasonable. 14:08, 18 August 2012 (UTC)
  • Try building bigger pen with more animals (in creative perhaps). The bigger a pen is the more visible the bug will be. In small pens it isn't visible. I will provide some screenshot later.
  • My largest farm has 100 block square pens and my smallest has 5x10 block pens, all with torches every 5 blocks, and though animals tend to "herd", they don't crowd together the way you describe. None of my pens has more than 20 of any one type of animal, but villagers will crowd regardless of numbers which I think is because of their AI behaviour with regard to doors, and since (I believe) animals are supposed to crowd around light sources, could this be a factor in what you're seeing, possibly crowding around a light source at night and not "resetting" during the day? Also, I play SSP on normal without mods in case that makes a difference. --KADC - "Be unreasonable." 19:03, 18 August 2012 (UTC)
  • I don't have any mods installed but I exaggerated a bit with description. Anyway here is a screenshot: As far as I know animals are attracted by light and grass and my animals have both in whole pen.
  • Looking at your screenshot, with some of the animals spread around normally but most of them crowded along the fence, I wonder if the animal AI is trying to disperse them away from the population centre when a certain density is reached. If this is the case, since villagers are able to open doors, if they had the same "dispersion" AI combined with a check to see how many villagers share the block(s) on the other side of a door, it could solve the villager crowding problem. --KADC - "Be unreasonable." 17:18, 20 August 2012 (UTC)
  • Animals don't crowd normally but when baby animals follow their parents they push their parents into corners because they're always trying to occupy the same space when it's not possible with more than one block of room. And the parent animals don't push back anymore either after 1.3.1. Without baby animals I don't see any more herding than what the animals' AI should do which prefers grass and light. 21:37, 21 August 2012 (UTC)

[A!] Most mobs (regular zombies seem to be an exception) have vastly exaggerated reach for their melee attacks, allowing them to damage the player from outside his own melee range and thus making it nigh impossible to kill them without taking damage. Classifying this as a major annoyance because it renders melee combat as a whole pretty broken and unfun. -- 05:14, 24 August 2012 (UTC)

  • Is it possible that you are experiencing a lag-related issue, because I have not observed this. Zombies, zombie pigmen, and endermen need to be within one or two blocks (hard to judge exactly) to hit me. Creepers also seem to be within one or two blocks before they explode (not including "countdown" explosions). Spiders lunge before attacking but the damage occurs when they are either one block away or in the same block as the player (again, hard to judge). --KADC - "Be unreasonable." 18:27, 24 August 2012 (UTC)
  • Can't deny the possibility, as I remember it having been that way in Multiplayer for a long time - but now that Singleplayer runs on a local server as well instead of being its own client, it happens there as well. The fact that I don't have this issue with regular zombies doesn't really fit the lag theory though. Furthermore, mobs like spiders and zombie pigmen are hitting me from positions where they really shouldn't be able to hit me; for example, I take damage while standing two blocks higher than the mob I try to attack, all while not being able to hit it back through the block's hitbox. (I hope you get the picture, but if not I could go make a screenshot.) Regular zombies, on the other hand, can't damage me in the same position; unlike the other mobs, they literally need to touch me to damage me, which is, in my opinion, the way it should be. I recall zombies recently having received an AI update (you know, better pathfinding and such), maybe that's why their reach is "normal"? I'm pretty sure most of the offending mobs haven't received any AI updates in a while... But that's just a theory of mine. -- 20:34, 24 August 2012 (UTC)
  • Possibly related to your not being able to hit back even though they can hit you, I am frequently finding that I cannot hit a mob a repeatedly unless it is moving. i.e. After hitting a mob once, further attacks pass through the mob as if it were not there if the mob stands still. --KADC - "Be unreasonable." 23:33, 24 August 2012 (UTC)
  • What you're seeing is probably a result of lag. On SSP and fast servers I can kill mobs without getting hit at all, but on slow servers I often get hit as many times as I hit the mob I'm attacking. This is especially noticeable when fighting skeletons, as the arrows can be visually seen to miss me by several blocks while still damaging me. --Swampert rox 22:26, 26 August 2012 (UTC)
  • But if it is lag, then why does SSP lag so hard during combat, and not against all mobs? I have no issues dispatching creepers without them exploding, and I don't randomly get hit by skeleton arrows that visually missed me. Zombies only damage when when they touch me. I also have no problems with my own hits not registering. But spiders and endermen damage me from roughly one and a half blocks away rather than only when actually touching me, and zombie pigmen seem to have an even greater reach (almost two blocks). Zombie pigmen can literally continue damaging me while I'm stunlocking them on soul sand from the very edge of my melee range. The only other instance in SSP that I can think of where I sometimes experience something that appears to be lag is when digging straight down, where blocks will sometimes reappear for half a second or so before successfully being registered as removed.
    Besides, even if it is indeed lag, I'm sure there's something Mojang can do about it? They could do whatever they did to Zombies, as, again, I'm not having these issues with those. -- 16:59, 27 August 2012 (UTC)
  • Probably related to this, but an annoyance anyways: Creepers tend to blow up too far away to deal damage to the player. Most of the time when closing up to a creeper, hitting a melee attack and backing off, the creeper will explode harmlessly. Chances are it damages/kills nearby hostile mobs in the process. Schevv 05:09, 13 September 2012 (UTC)
  • I believe this is a lag related issue. You THINK the mobs have greater melee range, but when they hit you, do they quickly "zoom" to you? this never happens to me unless my router begins losing connection (gotta get a new one...) See, if they are just zooming to you, like how endermen teleport, then you need a better computer and/or connection to the internet if on other servers. Trigger hurt 15:12, 30 September 2012 (UTC)
  • They do not "zoom" to me. I'm somewhat experienced when it comes to issues like these, and I think I can tell apart lag from inherent problems. Seeing how this is going nowhere, though, I think it's best to stop the discussion at this point and just let Mojang see if this is something they can fix (or maybe already fixed in the snapshots) or not. -- 20:02, 6 October 2012 (UTC)

[A] [SP] Cows, while trying to get through a fence gate following a player holding wheat, will jostle each other in front of the fence gate but will not allow other cows to pass through because the passive mob pathfinding algorithm does not have any code that determines whether a mob will give way to another mob in order to let multiple mobs through. Ideally, non-aggressive mobs should form some order when attempting to pass through a gate and both allow other mobs to pass through and give them reasonable space to do so. This annoyance is not limited only to cows, it's applicable to any mob that can be bred and which will follow the player regardless of whether it can be tamed or not. BrickVoid 07:08, 17 August 2012 (UTC)

  • I think it's time to do something about this, especially now that books require leather, zombies don't drop feathers, and passive mobs spawn only at generation. Such a fix would be consistent with skellies hiding in shadows and water when the sun is up. So, yeah, time to provide a way to easily get animals through gates, and I don't mind if it's a redstone prod. -- Featherwinglove 13:25, 18 August 2012 (UTC) (P.S.: Maybe I'll try a fishing rod.)
  • If gates could be "doubled" like doors would also help this issue tremendously, though I agree that an improvement to mob AI would be the best solution. --KADC - Be unreasonable. 14:08, 18 August 2012 (UTC)
  • Well you can actually double gates but of course it doesn't look good and you need redstone to open both at the same time. Open gate doesn't have collision so they don't have anything blocking passage between them. 21:37, 21 August 2012 (UTC)

[A] Tamed wolves bark for no reason when in the vicinity of the player.

[A!] Villagers apparently view animal pens (made of fences with fence gates for doors and no roof) as "inside" spaces. They cluster there at night, and often never leave again. I considered not reporting it, as it's kind of a minor thing, except that my villagers have started letting animals out and iron golems inside, meaning I get killed frequently when trying to butcher my own cows and accidentally hitting one of the 7-8 villagers who refuse to leave the cow pen. -- 13:18, 5 September 2012 (UTC) (can't log in right now, might reclaim this later)

I have only noticed it in SSP and Creative Single Player, but those are the only two modes I play. This even happens when the game is paused. --Bronsonboy 22:45, 24 August 2012 (UTC)

(No mods, texture packs, anything) P.S.: I moved this from an annoyance to a bug. --Bronsonboy 22:45, 24 August 2012 (UTC)

I can reproduce. This occurs with any tile entities - chests of all kinds, signs, falling sand/gravel, etc. It is, to say the least, extremely annoying and definitely a bug. Also, it appears to be a consequence of the new lighting engine - it has occurred since the Beta 1.8 update. --Cycloneblaze(user - talk) 15:47, 29 August 2012 (UTC)
  • Guys, this bug is for people who use a crappy computer, like a laptop. I know this because my computer runs a quad core processor, a memory card that lets me easily play far cry 2 without any lag at highest quality, but only 200gb of actual memory, about 80-90% used. I did a school project and my teacher used a crappy netbook, it ran surprisingly, but entities and tile entities appeared to glitch from black to their original textures, mostly black. It is very unhelpful, and annoying, and thank god i only spent 10 minutes on it otherwise i would have yelled at my teacher to get a good computer :D but it is graphical, which is VERY unhelpful for signs, since they are all about graphics.Trigger hurt 20:29, 27 September 2012 (UTC)

[X] In first-person view, the fishing line is not connected to the cast. --freaktechnik (w) 11:50, 2 September 2012 (UTC)

[A] From time to time, a pillar of color appears above a single block, reaching to the top of the world (as far as I see). The color has the same shade like the block texture, but blurred. e.g., above a stone is it grey, above water is it blue,... But strange, sometimes the color of this pillar is a randomly collection of different colors, has no context to the block color.
When changing the viewpoint, the pillar disappears sometimes. going back to the old viewpoint, it then comes back. sometimes more than one pillar appear. the pillar has no mass, you can go through without any drag. when load such a game, it sometimes disappears at all.

[A] Ever since the Local Server conversion was added to single player, you will often find an area which is completely black, and when updated will return to normal. RyanDolan123 04:37, 17 August 2012 (UTC)

  • I have not seen that before, could you provide me with a screenshot?
  • Duplicate of the "blocks under an overhang" bug reported above? Score Under 05:59, 20 August 2012 (UTC)
  • This is a lighting issue, anyway. It usually occurs under blocks, as Score Under said, so I think it's that bug, yes. --Cycloneblaze(user - talk) 15:47, 29 August 2012 (UTC)

[A] Connected textures are nice but you need to add a method of manually cycling the rotation of a block. the fact that you cannot cycle through texture orientations when placing connected blocks is annoying because the game tries to guess which way to orient the texture based on the way the avatar is facing and not what the blocks around it are doing. this leads to mismatched and really ugly screw ups in the orientation of joined textures.

[A!] For months I have tried to find out why my minecraft is messed up with the lighting. For some reason whenever it gets dark, the lighting turn blue and very dim so that you can barely see, even with the brightness all the way up. My dad downloaded the minecraft app to his computer and put it on a USB and downloaded it to my computer and it has the same problem, even when it doesn't on his computer. Brandonschrand 21:37, 19 August 2012 (UTC)

  • Finally, someone with my problem! I assume you have a Mac? This really breaks gameplay at night, and if you don't have a bed with you, things get really messed up when you try to see. It only occurs on really old Mac systems (before Intel processors became part of a Mac). I have only assumed that it related to the Java version, because my Java can only go up to 1.5.0_19, due to PPC core incompatibilities. Unless my system just happens to be the perfect (mis)configuration and everything, this seems like something that occurs in the Jar. Prior to 1.7.3, my lighting system worked perfectly. Now, everything lighting-related that occurs after 1.7.3 I can only assume will not function properly, due to such a bug. However, there are some hitches. For one, the majority of the glitches happen only at night. At day, lighting is the same as it should be. Torches light up properly, and the hue is correct. But for nighttime, it is vastly different. On the surface, everything is perfectly lit up and such, and renders torches useless when placed on the surface in direct skylight. This also interferes with caves when mining at night. Caves are supposed to be unaffected by changes of daylight, but unless it is in contact with skylight, where the cave would be lit up like at the surface (even at night), caves will instead turn dark and a hue of moonlight-blue, which is way too dark to see effectively, even with torches. Places like the Nether are also a tad too dark, and the only way to get it to be bright enough to effectively see, is to put brightness to max in-game, and, aside from that, also put the contrast, brightness, and gamma settings for the computer to their maximum settings. Deep underground, the void fog effect does not seem to take place, (on survival) and during a lightning storm, the lightning is able to light up the underground caves! As of recently, you can temporarily bypass the problem with a potion of Night Vision, which makes lighting like daylight. I assume that when you added moonlight, a part of the code was poorly crafted or vague causing blocklight to be gradated while restricted to skylight, and the constant light at the surface was caused by maximum skylight being the same, as if whatever parts of the code that were used were switched around. Maybe when you wrote it, it allowed the hue and maximum light level of skylight to be switched with blocklight, and that of blocklight to be switched to skylight. I could say from this that the surface is fully lit because skylight is to max out surface lighting to the max lighting in caves with the effect present in caves, and cave lighting is dark because it is set to max out features as they should occur on the surface at night with features corresponding to the surface, explaining the features like lightning penetrating deep in the caves, while leaving the Void fog absent. The code seems the only take effect in the block rendering environment, while items are not affected by this issue and are lit as they should be, meaning that mobs and entities, as well as things like maps, they are darken and lighted at the appropriate levels of light as before. The sky also goes from light-blue to black at night descends. Gradual transitions also take place. This is all theorized, and may be incorrect, as I do not know how to code Java. :C --Wormy14 13:25, 24 August 2012 (UTC)

[A] (This is the same bug that has been occuring for some users since release. It also has been reported before at least once. I will post a screenshot) There are certain points in worlds where surface texture on a certain group of chunks disappears (either for a fraction of second or as long as the player remains in the place). This happens in chunks both modified and not modified by the player. Dragomok 20:11, 25 August 2012 (UTC)

[?] There is a strange mark appearing in one of my creative files on superflat and this hasn't occurred before.BTW this game is vanilla --3MB0AR 00:07, 9 September 2012 (UTC)

[A] Signs are often blank. Only the signs in the near vicinity of where the player logged in or came through a portal will be visible. When going further most if not all of the signs will be blank unless I log out and back in. Really annoying when trying to find the right portals in the nether or the right chests in the storage room etc. (tested on MP) --Masa 08:11, 9 September 2012 (UTC)

[A!] When in short/tiny render distance, any textures with partial transparency, or alpha, is pure white. I have found this while working on my HD texture pack, and i don't have a superb computer; i only recently got one that could handle normal and far render distance. Its also hard to edit out partial transparencies while working in 64x. --AlexTheRobot




[X] Extinguishing fire by punching it doesn't produce any sound. -- 05:14, 24 August 2012 (UTC)

  • This is a survival mode bug for some reason. The extinguish sounds work on creative, but not on survival. Masa 12:44, 6 September 2012 (UTC)

[X] There is no sound when the player walks on sand. All other surfaces seem to play the walking sound properly. --KADC - "Be unreasonable." 23:52, 20 August 2012 (UTC)

Details? My vanilla 1.3.2 singleplayer on Windows Vista gives walking sounds on all blocks I've tested: sand, grass, farmland, stone, cobblestone slabs, sandstone slabs. Try a clean install in a separate folder to force all the packages to download and retry. -Aurelius 00:08, 26 August 2012 (UTC)
  • I first noticed this just because of clean install. I wanted to have fresh copy of minecraft in my storage space, so you try it Aurelius. EDIT: Tried reseting resources again without help. -- 20:40, 26 August 2012 (UTC)

[X] The tool breaking sound plays before a tool with unbreaking actually breaks. I believe (only a guess) it is doing this when the tool would normally break if it did not have unbreaking. --KADC - "Be unreasonable." 23:52, 20 August 2012 (UTC)

[X] I've checked all the usual culprits (in-game audio settings, comp. volume, sound card, etc.) but as of 1.3.2 I'm receiving zero audio be it soundtrack, sfx, or otherwise. ThunderKnight_Z 21:35, 18 August 2012 (UTC)

Did sounds work for you in 1.3.1? Try to isolate what changed on your system from when sounds last worked. Try a clean install in a separate folder to rule out a corrupted install. Does sound work for other java programs? For my 1.3.2 clean install, sounds work Ok expect for the usual occasional lag. -Aurelius 00:08, 26 August 2012 (UTC)

[X] Twice now, I've been doing various stuff (once bucketing water, once fighting spiders, but both cases where I was moving forward), and then turned around to find a new creeper crater behind me. Never heard the explosion.... --Mental Mouse 23:05, 4 September 2012 (UTC)

[X] All sounds echo or are stuck in a loop for a few seconds, e.g. breaking one pane of glass sounds like you are breaking many panes very quickly, rain and footfall sounds turn into a cacophony, creeper explosions sound like a rapid-fire mortar, etc. I don't think this is the same problem as the SMP "sound lag" annoyance below, as the initial sound does happen on time, it just rapidly repeats for a few seconds afterwards. I am running 64-bit Windows 7 Home Premium edition, Service Pack 1, on a Dell Inspiron 1545 laptop, with an Intel Celeron CPU (900 @ 2.20GHz 2.19GHz, if that's important) and 2GB of RAM. CPU Usage and Physical Memory never went above 30% and 45%, respectively, and there was no traditional (i.e. video) lag. Not that that matters - it even happens on the title screen (menu button clicks). Need anything else, just ask. Terminal Corruption 22:58, 14 September 2012 (UTC)

[A!] [MP] When standing still, the sound packet/packets are much slower and jitter, causing a delay when sound is sent to the client. When moving around, (flying, falling, walking, running, minecart movement, boat movement, etc), the sound packets are much faster, making audio much more fluid. This is on a multiplayer server in minecraft 1.3.2.

[A!] [MP] There is a large amount of "sound lag" on SMP (meaning sounds don't occur for a few hundred milliseconds after the action that caused them) that gets steadily worse the worse your ping is and the slower the server is. This happens with footsteps, block placing/breaking, picking up items, and taking damage. As a result, since the sounds still come from the direction where they happened at, it almost constantly sounds like a mob is following you. Placing blocks is also extremely annoying, (particularly when you are trying to count how many you've placed) and oftentimes you're able to place multiple blocks before you even hear the sound for the first one. 08:25, 27 August 2012 (UTC)

[A] It seems as though the stepping sound for walking is being played at almost the same frequency (if not exactly the same) as for sprinting. MerscratianAce 22:01, 16 August 2012 (UTC)

  • Hmm, this is not happening for me. Is there any chance that you can record Audio/Video of this? Sonickyle 16:07, 17 August 2012 (UTC)
  • Yes this is happening for me as well. But I like it because it also seems to be playing the footstep sound at the same time as your character's feet touch the ground while walking or sprinting. (Walk around and watch your character while in 3rd person view by pressing F5) - McLaren_231 (MC username) 9:10 21 August 2012 (UTC)




[X] This minor bug was first noticed in 1.3.2. Texture packs lacking pack.txt (the file which adds the description in the texture packs menu) are now reverting to the default pack.txt, making any texture pack lacking this file have the description line: "the default look of minecraft" Previously when pack.txt was omitted, the description simply didn't appear, many texture pack artists don't desire a description and have omitted it, so this comes up a lot. –Preceding unsigned comment was added by (talk) at 04:53, 31 August 2012 (UTC).

[X] [MP] The "Add server" and "Edit" screens on the multiplayer server list don't accept IPv6 addresses. "Direct Connect" works fine, as does manually editing servers.dat, so it's just the front-end validation code that's a problem. (To be correct, it should treat the entire thing as an address if there's more than one :, unless of the form [2001:470:db8:42::1]:25565, in which case the contents of the square brackets are the address.) -- Dagger 19:26, 9 September 2012 (UTC)


[A] This annoyance exist since Multiplayer and Singleplayer have merged. When you want to update the .zip file of a texture pack, you have to close Minecraft first or else every attempt to update the .zip file would fail and send you an error message because "the file you're trying to update is used by another programm" even if the game is runnig with another texture pack. Before 1.3 snapshots, I used to switch to default before updating my texture pack, then switch back to my texture pack and it worked fine.Missingno 26 13:01, 19 August 2012 (UTC)

  • I can confirm this, and it's annoying X-X It seems that Java will load all the texture pack files into memory, possibly for faster swapping, but this causes them to be reserved by the process, so they can't be modified. --Cycloneblaze(user - talk) 15:50, 29 August 2012 (UTC)


In-Game Interfaces/HUD[edit]


I'd like to know if there is a way to edit your uploaded minecraft skin, so I can have it so that my skin changes between texture packs online ( exactly like how offline skins changes between texture packs, but just working online and with server textures.)

[!] Occasionally, in the inventory, clicking (without holding shift or ctrl) causes the effect of shift-clicking (instantly moving it to the first slot of the inventory or the hotbar), making it impossible to drag and craft items.

  • You may have sticky-keys on. 21:16, 18 August 2012 (UTC)
  • This effect is not caused by sticky-keys. It occurs on both Windows and Macs (in my experience), will randomly start without the player having pressed shift recently, and lasts until the launcher is closed. --Swampert rox 20:52, 19 August 2012 (UTC)
  • I get this all the time. Minecraft just doesn't register the key release so you need to press and release it again. Updating LWJGL seems to have fixed the issue for me, though I think this might just be due to blind luck. Score Under 06:01, 20 August 2012 (UTC)
  • I get it too. I originally thought I'd been accidentally triggering sprinting, but the details don't support it. While I can believe that sprinting could work in any direction (including backwards), having it work for jumping seems a little implausible. This is a serious problem when I'm exploring the Nether -- way too easy to get auto-run over a drop or through fire. Contra my previous comment (which I'm removing, and which seems to have been transplanted from a different bug), I also fix it by pressing the appropriate key again. Of course, when I'm suddenly auto-sliding across a wall, it's not always obvious which is the correct key... I've been getting this or a similar bug since at least 1.2.5, and I was really hoping it would be fixed by now. --Mental Mouse 21:55, 23 August 2012 (UTC)

[A!] When editing a book, it's impossible to move cursor to beginning of line, page or other place in a page. So when you want to edit some text inside a page you have to re-write the entire page.

[A] Filling a stack of buckets from a lava lake, if you fill your inventory without realising it while you still have some buckets in your stack, it's highly likely you will accidentally throw a bucket or two into the lava. It would be better if you simply dropped full buckets (or anything else that causes an inventory overflow) at your feet. Dumping excess junk so that it lands by the crafting table you were just working at, for example, is fine, normally, but in the case of lava the default throw direction is going to tend to discard your buckets into the lava you're clearing. This quirk of game user interface is, um, not very helpful. -- 22:13, 14 August 2012 (UTC)

[X] /kill and /seed commands fail to work for anyone except operators. Using the commands tells the player they do not have permission to use that command. Hard to tell if they've changed the permission on purpose without putting it in the change-log. --Denney 14:00, 19 August 2012 (UTC)

[A!] Commands no longer log to the server. Commands used to log something like "[INFO] jorr issued server command: /seed" or "[INFO] jorr tried server command: /trololo". The change makes it hard to look for griefers/abusive admins. I believe the desirable behavior is to have all commands (including nonexistent commands, e.g. /home) should log to the server with "[INFO] <player> tried server command: /command [args]". Jorr 20:28, 4 September 2012 (UTC)

[A] In the update a lot of old commands like /gamemode were changed from /gamemode [Player] [Mode] to /gamemode [mode] [player]

  • I do like some of the changes, but on FlameZone PVP and other servers like it TooManyItems doesn't work properly, as it will make anyone with a 1 in their name change gamemode, for example the owner, allango100, or another admin/moderator enderman1234 changes their gamemode and it gets annoying for them.

Language/Text Files[edit]

[X] The "Snooper Settings..." text is still not translated.-- 07:36, 22 August 2012 (UTC)

[X] In Czech:
- Iron sword should be called "Železný meč".
- Jungle tree and all its products (saplings, leaves, logs, planks, stairs and slabs) are named incorrectly. The tree is called Sekvoj (= redwood tree) which is nonsense because redwood trees are conifers unlike Minecraft jungle trees which are broadleaf trees. I suggest calling it "Tropický strom" (= tropical tree).
Tropical tree sapling = "Sazenice tropického stromu", Tropical tree leaves = "Listí tropického stromu", Tropical wood = "Tropické dřevo", Tropical wood planks = "Prkna z tropického dřeva", Tropical wood stairs = "Schody z tropického dřeva", Tropical wood slab = "Půlblok z tropického dřeva".
- Flint should be called "Pazourek".


[A] In Czech:
- Blaze rod should be called "Ohnivá tyč".
- Jukebox is commonly used expression in Czech and shouldn't be translated. Moreover, "Hrací skřín" sounds silly and is never used.
- Creeper shouldn't be translated (applies to Spawn Creeper item).
-Silk touch should be called "Hedvábný dotek".

  • For this, and the above, I suggest you go to and help with the translation there. You seem to be knowledgable in Czech - they could use someone like you, I'm sure. :) --Cycloneblaze(user - talk) 15:59, 29 August 2012 (UTC)
