Minecraft Wiki:Issues/Weekly 12w16a

Organization of This Page & Instructions
'This page is for bugs that occur in the client or server of an unmodded'' Minecraft game. If you think a bug you have found in a modded version is not the result of the mods you have added, please be sure to reproduce it in an unmodded game before posting it here.'''

When reporting or commenting on a bug or annoyance, please sign your remarks with  ~ . This is a deliberate exception to the usual wiki conventions; normally you should only add signatures to content on talk pages.

Please do not spontaneously delete an issue report or comment unless it is patent nonsense submitted by someone who has not logged in. Try to contact the submitter by user-talk first and tell them about your concerns. Almost all genuine, active submitters will be co-operative. Always assume good faith.

If you're unsure of an issue, it's good practice to post about it on the |talk page to see whether others can reproduce it. Make sure you're testing the bug in the correct version (for this page, that's snapshot 12w16a) with no mods installed. Also, make sure to proofread your issue report before submitting it; unintelligible issue reports come off as inconsiderate and disrespectful. Finally, please determine which game mode(s) your issue appears in, and flag it with the appropriate label(s). (Also, note that if, for example, a minor annoyance appears in both single-player and multiplayer, and in both creative and survival modes, you should label it as a, not aspmpsucr.)

Please make sure issues are given the correct category, type, and priority: redstone issues go in the Redstone section, problems with mobs go into the Mobs section, and so on. List crash bugs !! first, then major bugs !, then minor ones undefined. Annoyances go into the Annoyances subsection, with major ones A! before minor ones A. Issues that have been marked as fixed or skipped are moved to the Fixed/Skipped section. Issues that Mojang cannot reproduce should be left in their original place.

Please sign all issue reports and comments by typing  ~  (three tildes; tilde may be found above on USA keyboards, and to the right of  on British keyboards).

There is no need to place bullet points before issue labels. Use bullet points only for comments. Be sure to leave a single totally blank line before each new issue (but not before comments), unless the issue appears directly beneath a header.

If a new version of Minecraft is released, create that page with. Any changes made to this header should also be made to this template.

Note: Please don't let debates about whether something is or is not a bug or annoyance get out of hand. Similarly, don't clog bug reports with discussions of workarounds or possible fixes. If ever a bug or annoyance ends up with more than about 10-12 lines of follow-up comments, please move the entire follow-up discussion to the talk page and put in a cross-reference to the discussion under the original bug.

Issue Labels
Please mark your issue with one of these issue labels: (listed from highest priority to lowest)
 * !! =  !!  = Critical bug that can crash a Minecraft client or server.
 * ! =  !  = Major bug. Use this tag sparingly; if there is consensus your bug is not major, it will be downgraded.
 * a! =  a!  = Major annoyance. Think very carefully before flagging an annoyance as major.  Is it really more important than most minor bugs?  Use this tag sparingly; if there is consensus your annoyance is not major, it will be downgraded.
 * undefined =  undefined  = Minor bug.
 * a =  a  = Annoyance.
 * ? =  ?  = Potential issue that you are unsure of or that the community (on the discussion page) believes requires further vetting. Note: do not use this label to indicate this-is-not-a-bug; instead, replace the issue's current label with [A] or [A!].  Furthermore, it is inappropriate to use this to flag something you disagree with; instead, express your opinion in a comment. When you apply this label to an issue, place it after the issue's existing labels; do not remove those labels.

Labels for indicating that an issue happens only in a particular game mode: (These labels cannot stand alone; you must use them in addition to, not instead of, the ones listed above.)
 * sp =  sp </tt> = Single-player.
 * mp =  mp </tt> = Multiplayer.
 * su =  su </tt> = Survival mode.
 * cr =  cr </tt> = Creative mode.

Labels for indicating that an issue happens only with cheats: (These labels cannot stand alone; you must use them in addition to, not instead of, the ones listed above.)

They don't exist yet, but should be added soon.

Labels for indicating that an issue is restricted to a particular OS:
 * =  </tt> = Mac OS X
 * =  </tt> = Windows
 * =  </tt> = GNU/Linux

Labels that Mojang (not you!) uses: (Please place these tags in front of existing issue labels; do not remove the existing labels.)
 * f = Issue for which a fix will appear in the next update.
 * n = Not a bug; intended behavior. By definition, this label is inapplicable to annoyances; annoyances are not bugs.
 * s = Issue that will not be fixed in the next update.
 * u = Issue that Mojang has tested but was unable to reproduce.

To produce these labels, use the following code:  </tt>c </tt> where c is the code of the label you wish to use. (e.g., a for annoyances, etc.)

The default issue type is minor bug; you can produce this label with the shorthand  undefined </tt>.

Crashing/System
Bugs !! ? all modes: When I push the Button Open Texturepack Folder Minecraft crashes. My System is Win 7 64bit, java 7u3 64bit, lwjgl2.8.3. It is a fresh Minecraft installation and a newly installed java.
 * Can confirm with the same specs. Game does not crash, but freezes without an error. Mustek 22:14, 19 April 2012 (UTC)
 * Yeah you are right, I used the wrong words. It freezes without an error.
 * The button works fine on my system. Win 7 64bit, java 1.6.0_24. Maybe its a problem with java 7? :/ --Mattrition 20:23, 23 April 2012 (UTC)

!! On SMP, updating from 12w15a to 12w16a (Java 1.5, PowerMac G5 Quad) the following error is displayed in the console when players try to log in (client also updated to 12w16a):

Additional detail: the player remains connected according to the server, even though the client gets an error also. Also seeing the following error when players are eventually disconnected:

Fixed/Skipped f !! Changing the GUI scale still crashes the game. NetherrackCreeper (talk) 16:42, 19 April 2012 (UTC)
 * THANK YOU MOJANG!!!!! NetherrackCreeper (talk) 20:24, 22 April 2012 (UTC)

Gameplay
Bugs ! Same error as in 1.2.5., Minecraft runs fine for exactly one minute until major lag and a crash. 8 gb of ram, 64 bit, Win 7 PC.75.132.35.214 19:03, 22 April 2012 (UTC)
 * Please try and post a crash report for your issue. Without that, this bug report is almost useless. --Mattrition 10:55, 23 April 2012 (UTC)

undefined More info on a long-standing bug: I was stationary (or possibly still moving very slowly) in a boat. Had traveled by boat for several days. One of my tame wolves, which had also been swimming for some time, teleported near to me then swam closer and 'bumped' the boat. Which instantly killed me. I was aware that you colliding with a mob in a boat could be fatal, but I didn't appreciate that mobs touching you when you were stationary could have the same effect. Flagging as major as this bug can kill instantly without warning. 82.69.54.207 21:39, 20 April 2012 (UTC)
 * I did some experimenting and couldn't get any pets to collide with my boat in a way that would kill me. However, on one occasion I was damaged by half a heart from a collision. It seems really random, but if fatal collisions happen they don't happen often. It's not game breaking and doesn't happen regularly, so I'm downgrading it for now. --Mattrition 20:44, 23 April 2012 (UTC)

undefined The player's directional arrow on maps is not properly aligned, and is off 22.5 degrees clockwise. When facing north, the arrow will point north-northeast. TorchicBlaziken 20:54, 23 April 2012 (UTC)

undefined Sometimes loading a world causes you to spawn at underground when you were above ground or vice versa. Presumably, the horizontal co-ordinates are the same.

undefined If the player saves and exits a world while in a boat or minecart, when they reload the world, they will fall out. Not tested in multiplayer.
 * This happens in multiplayer too --Mattrition 21:12, 23 April 2012 (UTC)

undefined mp When it is raining/snowing you cannot see if it is a thunderstorm or regular downfall.
 * What does this mean? You can tell its a thunderstorm by the thunder... --Mattrition 10:55, 23 April 2012 (UTC)
 * Yes, but the visual effect is not there in multiplayer, unlike in singleplayer <font style="color:teal;text-decoration:underline;">heldplayer 19:40, 23 April 2012 (UTC)

undefined The spawn point in superflat worlds are reset to a new location at every respawn. --Mattrition 23:09, 23 April 2012 (UTC)

Annoyances a Upside-down stairs and half-slabs inherit their light value from the block above them.

a sp When the Bonus Chest is enabled, if Minecraft populates that block space with another block, the chest is destroyed and the items in it become drops. This is especially susceptible to snow cover and jungle undergrowth. --Moxxy 22:20, 21 April 2012 (UTC)
 * In snow-covered areas, there are no Bonus Chest, nor the items from it.188.147.35.186 13:12, 20 April 2012 (UTC)

a mp When rain/snow starts on a server, then no starting animation is done. For reference, in single player downfall starts by slowly fading in. The same applies when weather stops.

a cr If a block is broken under a placeable item, such as a redstone torch, the item will yield a drop. This has happened since creative mode was introduced.

a Sprinting in lava created red lava particles Pbfy0 11:40, 21 April 2012 (UTC)
 * Sounds more like a feature if you ask me.... --DigiDuncan 15:01, 21 April 2012 (UTC)
 * I agree. Unless there's something that the person who added this isn't telling us (who we can't see as they didn't sign this) then this should be removed. --Moxxy 22:22, 21 April 2012 (UTC)
 * Even if its unintentional, is there really anyone who is "annoyed" by this? :p --Mattrition 10:57, 23 April 2012 (UTC)

a cr Using the /kill command, you can kill yourself in Creative mode.
 * How is this an annoyance? It's a command to kill yourself, after all. --Trinistr

Fixed/Skipped F undefined cr When using raw fish to tame ocelots, or dyes on sheep, or saddles on pigs, it is depleted, even in Creative. TorchicBlaziken 18:31, 19 April 2012 (UTC)

Blocks
Bugs undefined Glass panes do not drop themselves when harvested, even when using silk touch tools.
 * They shouldn't do normally, just like glass blocks. I wonder if you can harvest glass blocks using silk touch? --Mattrition 10:55, 23 April 2012 (UTC)

undefined When pressing the Pick Block button on a Huge Mushroom block of any kind, top or stem, it will give you a stem block, unlike shears would.

undefined Redstone Ore activates (glows) when it is right-clicked (WITH ANYTHING IN HAND). The Redstone Ore cannot stop glowing after it is activated in this way. (12w16a) --Starport592 00:00, 24 April 2012 (UTC)

Annoyances a! cr If the End Portal blocks in the End are broken, there is no way to replace them, not even with the new cheats. TorchicBlaziken 18:25, 19 April 2012 (UTC)
 * Can't you give yourself portal blocks? /give 119?
 * You can, but they will not place if you do so outside of the Overworld. There's a flag that says that if the Ender Dragon's defeated, End Portals won't decay, but this only affects End Portals in the world, and it does not enable you to place them. I suppose this could be fixed by allowing the placement of End Portals in any dimension, like you can with the Nether Portal block. TorchicBlaziken 00:47, 22 April 2012 (UTC)

a Grass blocks under upside-down stairs become dirt.

Items
Bugs undefined Boats can be placed on land. They act as if they are in water, complete with blue spray particles, but will only move very slowly. --Mattrition 21:09, 23 April 2012 (UTC)

undefined Mushrooms can't be placed in moonlight. It's probably worth mentioning that in moonlight the debug menu says that sl is 15.
 * Downgrading to minor bug as this is not game breaking behavior. Shikamaru123 07:01, 21 April 2012 (UTC)

undefined Entering or exiting a minecart or boat with a full bucket selected causes the bucket's contents to be emptied onto the block you are targeting. --Mattrition 23:15, 23 April 2012 (UTC)

World Generator
Bugs undefined World generation is often creating very large amounts of chunk errors. (cheats and chest enabled, vanilla)
 * http://i421.photobucket.com/albums/pp293/Kittani1977/2012-04-20_013048.png -- Kittani1977
 * http://i421.photobucket.com/albums/pp293/Kittani1977/2012-04-20_015635.png -- Kittani1977
 * looks like the old worldgen-version-difference problem, you took an old world and loaded it with the new version. but the the worldgen wasn't modified it shouldn't appear. --MG127 16:39, 20 April 2012 (UTC)
 * These were fresh vanilla generated worlds. I always generate a few dozen random ones every time.  It's possible some of the unmentioned "minor bugfixes" could have introduced a chunk load error, or generation error. -- Kittani1977
 * Another important thing to note is that if you take the seed and re-generate the world it will often come up correctly. This was after several times generating a world, looking around for a minute, then deleting and making a new one.  My guess is save file handling issues.  -- Kittani1977

Mobs & NPCs & Animals
Bugs ! mp Mob movements are glitchy in SMP, leading to the following issues:
 * 1) In a pen farm animals will appear to jump over their fences, and wander out. If the server does not shut down, they will be pulled back into their pen eventually. They can also "jump" onto the top of the fence. Keybounce 08:24, 5 April 2012 (UTC)
 * 2) Captured animals (also mobs) seemingly appears outside 1 block thick 2-3 block high room, mainly the roof (like they were getting out). If there is no roof they appear top of 2-3 block high wall. You can collide with these glitching animals. (pics from 12w04a) --93.106.240.108

 * I've moved and merged what I reckon is the best representation of the glitchy mob prediction in SMP. --Mattrition 15:52, 23 April 2012 (UTC)

undefined Wolves and cats will walk into cacti. For me this has resulted in the deaths of my poor wolves and cats when I take them through deserts. TorchicBlaziken 00:45, 22 April 2012 (UTC)
 * Most definitely not a major bug, and is possibly even not a minor one, just a little annoyance. I'll change it down to minor for now. --Mattrition 15:20, 23 April 2012 (UTC)

undefined Wolves and cats teleport into bottom slabs instead of onto them. TorchicBlaziken 00:45, 22 April 2012 (UTC)
 * Similarly, I have seen tame wolves seen teleporting into chests as they arrive.82.69.54.207 14:59, 22 April 2012 (UTC)

N undefined Spawn eggs spawn adult villagers again rather than the recently added baby ones.

Annoyances a Ocelots don't eat raw fish.
 * This annoys me, but its not a bug. Therefore I made it an annoyance. --Mattrition 11:07, 23 April 2012 (UTC)

a Snow golems do NOT produce snow in plains, swamps or mushroom biomes.

Main Menu/GUI
Bugs ! When you try to reset the demo world in demo mode, you can't return to the main menu by clicking "Cancel". --Barracuda 16:13, 19 April 2012 (UTC)

Annoyances a! The Debug Menu does not display the coordinates by chunk. TorchicBlaziken 02:43, 22 April 2012 (UTC)

a! Update Launcher. So you can choose a folder to start minecraft from. It's a pain always to copy minecraft, every snapshot or when you want to play on a server with a different version, from one folder to another. Not to mention the mods and so on. Thanks for reading. reptile311

a In More World Options (when creating a new world), if fullscreen is entered (or windowed mode), the buttons for structure generation, allow cheats, etc. disappear and 'Done' is replaced with 'More World Options.'

Crafting/Interface
Bugs undefined Enchanting tables do not go above enchantment level 13, no matter the number of bookshelves. --H8no1 17:09, 22 April 2012 (UTC)

undefined You can only shift click 2 of the 3 slots in the Brewing Stand, the third must be manually placed. --H8no1 23:56, 22 April 2012 (UTC)

Annoyances

Commands
Bugs undefined sp The "/give" command in the new single player cheats feature still requires you to type your Minecraft username as if you were on a server. This is not a problem with the "/gamemode" command. NetherrackCreeper (talk) 16:33, 19 April 2012 (UTC)
 * You can type in any text for name, so it's looks more like an annoyance to me. --Trinistr
 * I've moved this to annoyance, as you can just type anything, even "a", and it will give it to you. TorchicBlaziken 18:25, 19 April 2012 (UTC)
 * It still doesn't seem like the right behavior, even if you don't have to type your minecraft name again and again. NetherrackCreeper (talk) 18:39, 19 April 2012 (UTC)
 * I'm upgrading this to minor bug. This is not intended behavior and the fact that you can enter anything in that space attests to that. Shikamaru123 05:47, 20 April 2012 (UTC)

undefined mp The "/time set night" command sets the time to 12500 ticks in multiplayer. So it does not actually switch to night (18000 ticks/6PM) CasVg2012
 * /time set night is not a default server command, that's a mod one... Vandesdelca32 17:20, 20 April 2012 (UTC)
 * Incorrect, "/time set night" is part of this snapshot. Dinnerbone 13:45, 21 April 2012 (UTC)

undefined Resizing the game window wipes whatever you were typing into the talk box. --Mattrition 22:58, 23 April 2012 (UTC) Annoyances a New xp command is limited to 5000 xp at a time even though such limit is not connected to any level cap or similiar thing. --Trinistr

a! The were unusual. Why don't you use for help like in multiplayer?
 * I think you've misunderstood the use of tab. Its for autocompletion of long commands, just like in linux shells. --Mattrition 11:07, 23 April 2012 (UTC)

a! The is not recognized in Macintosh, hence making tabbing through commands useless

a The "/" key for opening the chat/cheat box is still not working properly in some keyboard layouts such as Portuguese Brazilian, where it is triggered by the ";" key. --RichardG867 20:17, 19 April 2012 (UTC)
 * Can confirm for QWERTZ hardware keyboard on OS X: no matter which software keylayout I use, the key that opens the ch(e)at box like this is always the one to the left of the right key (where  is on a US keyboard layout) 79.225.51.67 03:49, 20 April 2012 (UTC)

a The /gamemode command doesn't work in SMP if it is being used on someone other than yourself. For example; typing "/gamemode <random username of other player> 1" does not work like it used to. It says "<random username of other player> is not a valid number". This is annoying if I want to change the gamemode of one of the players on my own.
 * That is because the syntax has changed. It's /gamemode [player] instead of /gamemode Dinnerbone 13:43, 21 April 2012 (UTC)

Fixed/Skipped f undefined mp When using the "say" command in the server console, instead of displaying your message, it displays, "Usage: /say <message ...> even though the message is delivered.

Graphical & Lighting
Bugs ! At night entities such as the player, mobs, and items dropped on the floor are the only things that get darker. This leaves a night sky over a daytime landscape. Also torches, glowstone, lava, etc. don't provide any light so the only way to light up your home is to have the "sunlight", from night not working outside, shine in through a block marked as transparent. An example of this is being in a box full of torches and still being in complete darkness. This makes caves perpetually dark and impossible to light up without digging all the way back to the surface above what you want to see. The lighting has been this way since 1.8 at which point, in the version (snapshot/prerelease?) which allowed you to quickly cycle the sun and moon, I did so to see how it worked, the lighting worked great for the first night but it hasn't worked since.
 * Does this happen on just one of your saves? --Mattrition 16:53, 23 April 2012 (UTC)

x Occasionally patches of water are crystal clear. I first thought this might be river biome related, and intentional, but then I found this patch of clear blue sea: Simons Mith 19:13, 20 April 2012 (UTC)

undefined Wolves appear black, or at least extremely shadowed, when swimming. They return to their normal colour after their "shaking" animation --Mattrition 20:47, 23 April 2012 (UTC)

Annoyances

Language / Text files
Bugs

Annoyances a Not every block has a tooltip, even though all of them are available if cheats are used. TorchicBlaziken 15:31, 19 April 2012 (UTC)
 * Like portal or end crystal blocks or whatever. 88.110.121.225 15:50, 19 April 2012 (UTC)

a The End Poem is only in English, rendering it meaningless to players who don't understand it. TorchicBlaziken 18:27, 19 April 2012 (UTC)
 * I'm pretty sure Mojang is aware of this... --Moxxy 20:37, 19 April 2012 (UTC)
