Minecraft Wiki:Issues/1.2.5

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 1.2.5) 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.

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 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

U !! Shift+clicking coal into a furnace that has some coal already in it will crash the client (tested on two servers, not sure if its a problem with LWC).

U !! If you right click on a jukebox while holding a redstone torch, the game crashes (I haven't tested if it is the same with any other items.). Onatfb 20:08, 21 April 2012 (UTC)

! when in creative well building you can Sit in midair and you dont move and everything will disappear and the game will be all blue and you cant See yourSelf or buildanything and can Screw up your game and you cant do anything about it but delete the world
 * this does not crash anything, downgraded to !

!! ? When running minecraft (even without a .minecraft), once update commences, it freezes randomly while downloading a file(at 38, 50, or something else) and completely stops doing anything. Win 7 64 bit. Then, after a few minutes, it gives me: Fatal Error Ocurred(4): Connection Reset Retreiving: minecraft.jar 50% @ 665.27 KB/sec
 * Googling this issue, it sounds like you should try disabling your anti-virus and firewalls and then try again.--Mattrition 10:27, 7 April 2012 (UTC)
 * try using the browser to update and then run with the regular launcher, also happens with many 32 bit EXE files on a 64 bit system

!!If attempting to access the menu, the inventory or the chat for the first time in a Minecraft session while the Minecraft window is on a secondary display in dual display mode, Minecraft will crash, leaving a black screen and no crash report. This can be avoided by opening the menu, the chat or the inventory before moving the Minecraft window to the secondary display. LaserCucumber 21:54, 10 April 2012 (UTC)

U !! If I left and right click a sword or any item or block, as in attack and place keys, my Minecraft crashes on both servers and clients, and on survival and creative (Haven't tested on Hardcore) !
 * Hmm, I think we need more details on this one, and also, removed unneccesary tags (! and A!), moved it a bit higher to fit into the proper sorting. This does not happen here. Bilde2910 06:02, 15 April 2012 (UTC)
 * Unable to reproduce in unmodded client. -- Orthotope
 * same, unable to reproduce, what OS do you use, windows 7 lets me do this just fine, the animation looks weird in opinion though...

! Installed MC from fresh launcher on new computer. Most sounds and no music playing in game. Check of resources directory revialed that only newsounds subdir was downloaded. No other resource files were downloaded by new launcher/updater even with a 2nd forced update. Possible that baseline launcher is not fully checking/downloading all files required for the game beyond just resource directory. (Win7-64)
 * You Need to run Minecraft a couple times to make it work.
 * Able to reproduce. It happens sometimes to me too. --Anoymous712 03:42, 21 April 2012 (UTC)

! Just got a brand new gaming PC, but Minecraft will run fine for a minute then lag massively and/or crash. Also just got latest version of Java.
 * This is not a helpful report. Please post your system specs, what kind of minecraft you were playing (MP, SP, Cr), and how it went about crashing. --Mattrition 21:45, 12 April 2012 (UTC)

Sorry for short report. My new PC is running Windows 7 Home Premium with a 5.9 Windows score and 8.00 GB of RAM. 64 Bit. Minecraft lags massively after about 1 1/2 min. of perfect runtime until it stops responding and Windows gives me the option to end the process.

The same thing is happeing to me, it also gets a green line through it and will crash all the time, i have about the same specs-The_Tardiest Now the fine runtime is getting shorter and shorter, now down to thirty seconds. Minecraft is virtually unplayable now! I think the HD patcher shortened the lag-free time quite a bit, but I have no other mods installed. Please help!!!!!!

Can anyone reproduce this? If so, please respond.

I got same bug. By me it's happening often after much longer, around half an hour/an hour of gameplay, but it will happen every time eventually. Suddenly in the upper left corner some strange ranmdom pixels appear, most often green and white. In the same time blinking green line appears, leading from these into one of inventory spaces in my hotbar. The number of an item in this slot, if it has any, begins to blink strangely too and gets a blinking lime shadow. It happens most often with the inventory space i'm currently using, but it's not the rule and it does not disappear after i switch to another inv. space. After round 20 minutes Minecraft begins to lag, and some time after crashes, leaving no bug report, "saving chunks" screen or blackscreen, it simply closes the application. After a few times Windows may alert me, that Minecraft made the bad operation and has to close, and after a few more (they appear faster and faster) whole system is lagging and old Minecraft windows will not close despite clicking "close now". If I try to run Minecraft then, it will shortly tell me, that it has run out of memory. The only way to fix my computer then is to reset. Memory leaks probably? I got Windows XP, 32 bit Java and graphic card from 4 years ago, I play on Far and Fancy ^_^ 77.254.109.16 12:29, 24 April 2012 (UTC)

Alright, now that it has been confirmed, does anyone have a real fix to the bug? The only thing that works for me is the OptiFine mod, but I want to play vanilla Minecraft. PLEASE look for a fix!!!

!mp Shift+Click behavior occurring when not holding shift while within: Inventory and Chests [Survival] and Item Menu [Creative] Moving them automatically to a free spot [Survival] or giving you a stack of the item you click on / inability to move item from the hotbar. [Creative] KHRoxas 16:56, 10 April 2012 (UTC)
 * watch SethBling's vid on bugs, the shift key sometimes gets stuck, happens to me on survival, try optifine with "SMOOTH INPUT: YES"

!mp If an RCON connection drops unexpectedly (network issue, or rcon client is force crashed) the console is spammed with "IO: Connection reset." This generates massive amounts of log spam (40kb/sec), and continues until the server is closed or presumably the disk is filled.

! If you have a superflat world from 1.1, dying will delete ALL OF YOUR CHANGES!!! Possibly because of the Anvil conversion.
 * I think the problem is that superflat worlds don't have a set spawn point so when you die, the game picks a random spot to respawn. Your changes aren't deleted, but unless you pressed F3 at some point before you died, it's near impossible to find them again (in which case, use something like MCEdit to find them. This problem has been around since the Superflat world generator was added. NetherrackCreeper (talk) 19:57, 18 April 2012 (UTC)

undefined Cmd + Q still doesn't make Minecraft to quit. Tested on OSX 10.7.3 - Lion
 * I reproduced this on Mac 10.6.8.

undefined mp Labeled as Fixed on the 1.2.4 bugs page, still exists for me: After executing a command in the chat box, Minecraft will not exit the entry box thus the player is stuck in talking mode. Entering another command or text will, on a few occasions, give the opportunity to exit text mode. In most cases anyway, it will write another line beginning with a slash. This deprives the player from using command such as /tpa, /home or faction related command. This did not occur before 1.2.4.
 * Unable to reproduce this. Can you give us a screenshot of your Controls option screen ? --EvilSeph 17:08, 4 April 2012 (UTC)
 * Here are my settings []
 * Not fix at all --Hactarus 14:21, 5 April 2012 (UTC)
 * Got this problem too: after typing /help in talk mode (pressing T then /help), you're stuck at a "/" prompt which eventually disappears when typing "//" or "///", it's a pretty annoying bug as it blocks all controls (even pressing escape key doesn't get you out).
 * Seems to be related to video card/architecture NVidia/Sony (VPCEH for instance) exhibits it while Toshiba/ATI Radeon does not - hope this help. For the record v1.2.3 was working for both plateform.
 * This does not appear related to NVidia/Sony alone. I am getting it on a AMD Radeon HD 6950 using catalyst drivers (fglrx). Hardolaf 14:29, 14 April 2012 (UTC)
 * There's discussion on this at the Minecraft Forums. Both nVidia and AMD cards are hit, both Java 6 and JAva 7. Possibly only 64-bit machines/installs? --Freso 12:27, 20 April 2012 (UTC)
 * Lwjgl update don't work --Hactarus 13:40, 24 April 2012 (UTC)
 * Maybe it's because when you press "return" it exits the chat and then re-enters it...
 * My guess would be that it's because the new feature (introduced in 1.2.4) where the slash key also opens chat. (workaround : use the spoutcraft client) --snoepje0

undefined When seeing the debug screen (F3), you can hit the escape key and the debug screen shows over the buttons in the menu screen. When pressing the "Save game and quit" button, there is a fake "Saving chunks" screen
 * The "fake" Saving Chunks screen's always been there. The game saves the chunks when you quit.

undefined? Opening the texture packs from the main menu is fine, but when you press the "Open texture pack folder" crashes Minecraft. 64-bit Windows 7 with Nvidia GeForce GT 540, 8 gigabytes of ram, and Java 6/7 (I don't know, but I've tried this on both. Has been a problem since 1.1). This should not be a problem and it is a pain to go into AppData every time I want a new texture pack. EDIT: EDIT: EDIT: (I know spam, but this is important): THIS IS AN NVIDIA AND MINECRAFT PROBLEM! I ran Minecraft with Intel Integrated Graphics blabla (because on other computers that's what they used and it worked) AND IT WORKED! There is some sort of conflict between Nvidia and Minecraft because IT DID OPEN THE FOLDER WHEN RUNNING INTEL HD GRAPHICS or whatever.
 * Discussion on Talk Page

undefined Taking screenshots in Minecraft sometimes fail, with the remaining buffer elements mismatch with a certain requirement. This has happened before, with modded clients, but the bug has now also started showing up in vanilla Minecraft. Screenshots with META-INF open and also this one. I have Win7-x64 with Java 1.7.0_02-b13. If you need more detailed specs, please ask. Bilde2910

undefined Taking a screenshot in full-screen mode fails and displays this message: "Failed to save: java.lang.IllegalArgumentException: Number of remaining buffer elements is 1229760, must be at least 3057108".
 * This is almost the same as the one above. Bilde2910 20:29, 14 April 2012 (UTC)

undefined When quitting, Minecraft crashes, leaving a black window. Least-harmful time for it to crash, but it still shouldn't happen. -- Orthotope 07:16, 15 April 2012 (UTC)
 * Confirmed on my machine: Ubuntu 10.10 using the FAIF radeon driver (R300). --Benanov 19:17, 18 April 2012 (UTC)
 * Also seeing this on an up to date Fedora 16 install with an NVidia Geforce 330M
 * I am also seeing this with Fedora 16. Quitting the game while in fullscreen does not give me a black window though. MTP123654 02:30, 24 April 2012 (UTC)

undefined In fullscreen (F11), you can't turn properly - it stops when the mouse cursor (not visible) reaches the edge of the screen. Windowed (including maximised) works fine. Ubuntu with nvidia driver. -- 2.24.0.31 11:25, 21 April 2012 (UTC)
 * I have this issue, but I have also found a workaround. When in fullscreen, open a GUI, such as your inventory, and exit out of that GUI. You should now be able to move the mouse freely. I am pretty sure this is caused by Minecraft not capturing the mouse completely. MTP123654 02:28, 24 April 2012 (UTC)

undefinedmpsucr When wandering about far from where you left them seated pets (dogs/cats) that you left in certain areas will randomly spawn to you. So far I have had an average of 6-8 pets jump to my location on a few different occasions and separate log ins. 21:15, 15 April 2012 (UTC)X-Lander

This is also happening to me since 1.2.5 where all my pets are porting to me several times in a play session. I have to run back to the house and make them sit again. Valgarg

Same to me in SP on a Mac. Also wild cats and wolfs spawn next to me.

undefinedsu In 1.2.5, Minecraft still crashes ("Saving Chunks"-screen) when you have an enchanted item with Fortune greater than three. This happens mostly in custom made maps, since Fortune IV or above is unobtainable with normal enchanting. Error message: java.lang.IllegalArgumentException: n must be positive at java.util.Random.nextInt(Unknown Source) at jq.a(SourceFile:13) at pb.a(SourceFile:535) at pb.a(SourceFile:527) at pb.a(SourceFile:711) at aes.b(SourceFile:61) at aes.a(SourceFile:73) at net.minecraft.client.Minecraft.c(SourceFile:1230) at net.minecraft.client.Minecraft.k(SourceFile:1558) at net.minecraft.client.Minecraft.x(SourceFile:719) at net.minecraft.client.Minecraft.run(SourceFile:671) at java.lang.Thread.run(Unknown Source) --130.83.20.73 23:33, 19 April 2012 (UTC)

? Skeletons can very rarely shoot you through seemingly impenetrable barriers (ie. A 5-block thick cobblestone wall!) This could be potentially VERY dangerous if you are low on health in a mine or someplace and then you get shot by a skeleton you never saw, losing all your valuable loot in a new uncharted branch of your mine. This happened to me once on singleplayer survival. I wasn't able to recreate it ever again.

This has happened to me also multiple times when my attack (whether sword or bow) causes knock back to the skeleton pushing the skeleton into the wall. Running around a corner will make the skeleton come out after me. Valgarg


 * Isn't it much, much more likely you were shot by another skeleton you didn't see at all? You can't credibly flag as a 'major bug' something that happened once that you can't even reproduce. Especially given the most likely explanation in an "uncharted branch of your mine" is getting sniped from some other hidden opening. Downgrading for now from ! to ?. If you do manage to reproduce it, put it back. 82.69.54.207 23:50, 20 April 2012 (UTC)

!! On a 12w16a world, pressing T and then / crashes the client. (tested with SPC 3.2.2, Minecraft 1.2.5)

Annoyances

a After creating a nether portal, I walked in and it crashed. It won't let me in nether no matter what I try!
 * Unable to recreate this issue, need more details. NetherrackCreeper (talk) 18:47, 12 April 2012 (UTC)
 * Grammar fixed. UNABLE TO REPRODUCE

a! In Vanilla, totally unmodded, I cannot right click with food and eat it, but can still right click with tools such is a fishing pole. This is a major annoyance because I cannot replenish my hunger bar and regularly die because of this.
 * I don't seem to have this problem. NetherrackCreeper (talk) 18:47, 12 April 2012 (UTC)
 * Are you sure you are holding the right-click button? Bilde2910 20:35, 14 April 2012 (UTC)

a On IBM t43 windows 8 Consumer preview, the mouse pad freezes up while moving. So you walk straight. Using the rat(small mouse nub on laptops) works just fine. Just a warning to fix this when win 8 comes out.
 * This is a bug within Windows 8, some laptop drivers crash unexpectedly and fail to notify windows or windows fails to notify the user.

a If you take a picture of anything, (screen shot) and click on the title of the picture on screen, it attempts to open it as a link(not sure if intentional)

a Whenever I am in the middle of a game or getting back on, it will go to the 'Saving Chunks' screen for no reason. I can only break/build about 25 blocks without seeing that screen.

a! Major lag when in the uppermost areas. I'm experiencing it in a massive fake tree with glowstone in the branches. Perhaps it has something to do with light going into the top?

Fixed/Skipped

Minecarts/Boats
Bugs F x cr Using the Pick Block in creative mode on a minecart will give bedrock instead of minecart. Tested in 1.2.5
 * This happens with all entities. 207.190.166.40

undefined Getting into a boat with a water or lava bucket in hand causes the contents to be dumped if there is a selectable block on the other side of the boat. Cactose
 * Confirmed in 1.2.4, 1.2.5 pre-release, and a 1.2.4 world just updated today to 1.2.5 update. All 100% vanilla clients and worlds. Bucket empties when getting in or out of the boat if there is a selectable block within range behind the boat. Random seed used: debug. I copied Cactose's report above from Known bugs/Version 1.2.4 to Known bugs/Version 1.2.5. -Aurelius 15:59, 4 April 2012 (UTC)

x cr ? Sometimes when creating a boat when right next to a wall(facing it) if the player gets into the boat you may glitch through the wall seeing the whole of the underground. However the player will be stuck.

undefined mp When placing a rail on the topmost layer of the map, placing a minecart on this rail will fail with the message "Height limit for building is 256", as if the minecart were a block.
 * Is this really restricted to multiplayer? Sounds like it could be a general problem with the client. --Mattrition 15:18, 11 April 2012 (UTC)
 * I don't know, I tried it and the problem only affected me on multiplayer. Singleplayer worked as normal. NetherrackCreeper (talk) 20:14, 11 April 2012 (UTC)
 * Confirmed that this does not occur in singleplayer.--Cube3 02:25, 18 April 2012 (UTC)

Annoyances a! Landing a boat onto slabs causes fall damage. First time it happened was on hardcore mode and at full health it insta-killed me, when trying to recreate it, I only took one heart of damage for several different tries. The first time it killed me I had cobble slabs, the with the other tries I used wooden, still on hardcore mode. All times I just gently coasted onto the slabs, I was not going fast.

a When getting off a boat, the player falls through it rather than stands on it. It also causes the boat to be pushed away and easily wrecked by nearby blocks.
 * Downgrading to annoyance--Cube3 03:58, 10 April 2012 (UTC)

Fixed/Skipped

Redstone/Pistons
Bugs ! Jungle tree leaves will replace piston blocks when they grow. --Datsun80 17:17, 10 April 2012 (UTC)
 * Discussion and more info on Talk Page

!Redstone repeaters can freeze. Appears in loop circuits, the input at 1, the output staying at 0. It seems to involve game reloading / disconnect and reconnect. A way to restart the circuit (it will eventually freeze again) is to remove the input redstone wire and place it again. Or anything that causes the input to be updated. Very important bug, also existed in 1.2.3 and maybe earlier, please fix ! (SMP, Linux 64 bits)


 * I've had the same issue on SMP,Win64 but it's not limited to a stuck repeater. I have a simple clock (one repeater and one redstone torch) powering two pistons and when moving away from the clock so the chunks unload and returning will frequently stop the clock in either the repeater or redstone torch cycle.


 * As of 1.2.5 single player survival, whenever I turn off my redstone torches(on purpose), occasionally they will not, while capable, turn back on, unless I destroy it and replace it.

! Like slabs, glowstone, since 1.2.1, will not cut off redstone connections. It's not annoying, I quite like that fact. I just don't think it's intended.

!While functioning (does not involve game reloading or anything), pistons can place themselves in a state simultaneously extended and not extended. This state never changes until the extended block is broken by hand, which restarts the circuit. This happens only for certain designs, but happens often. Very important bug, exists since 1.1.0 (see the 1.1.0 known bugs to reproduce, but I don't known if it is the only way to produce it), please fix ! (SMP, Linux 64 bits)

undefinedBug where piston is powered by invisible power source after stacking it on another piston and not powering them on at the same time. This makes the spot unusable for pistons. Found on a craftbukkit server. Only essentials and group-manager installed.

24.192.246.237 23:21, 4 April 2012 (UTC) Will
 * I've try that in vanilla minecraft and it's the same thing. CharlieKopaka794, 18 April 2012
 * Always try to reproduce the bug in vanilla minecraft, no matter how unrelated the mods installed are. We can't take it seriously otherwise. --Mattrition 01:10, 8 April 2012 (UTC)

undefinedRedstone torch burns out on multiplayer (only survival tested). Redstone circuits which should generate a stable clock pulse normally rely on NOT gates. NOT gates burn out the redstone torch. Replacing the torch will not help, as it will burn out immediately on the next switch. This happens only on multiplayer. Circuits in single/creative are fine. No mods installed. The bug is trivial to recreate, try any of the clock generators that rely on a NOT gate (all of them), observe for about 20 seconds, the circuit will stop working. --Siebren 08:20, 5 April 2012 (UTC)
 * Someone else reported the following: (also found same problem on Mac OS X version (creative mode tested only)
 * Someone relabeled this as an annoyance and creative only. It is a bug and it does not appear in creative only, please do not relabel a bug without good reason. --Siebren 08:02, 6 April 2012 (UTC)
 * Bug appeared in Creative Superflat, redstone torches do not change state when their block is unpowered,but not always.(Relabeled to Mp and Cr)Wigglewiggle 14:30, 6 April 2012 (UTC)
 * I took the Creative label off because it is not restricted to creative. --Mattrition 15:59, 6 April 2012 (UTC)


 * Someone removed Multiplayer Only because the proplem is not restricted to multiplayer.
 * This happens for me in survival single-player, anyone else have that problem? (Mac OS, Minecraft 1.2.5)

a!When you repeatedly power a block with a redstone torch on it the torch will eventually burn out. However, every redstone torch you place in that spot afterwards will burn out when powered, even when powered with a button or switch. Reloading the world does not fix this problem.--Myrmeleon 17:44, 26 April 2012 (UTC)

undefined sp Standing middle of block that piston pushes sideways, makes you fall through pushed block. (tested csp, cmp) 88.194.211.57
 * This is caused by pistons pushing being an entity, it's an (probably) unfixable bug. 190.125.69.183 01:02, 6 April 2012 (UTC)

undefined mp sp Like slabs, glowstone, since 1.2.1, will not cut off redstone connections. It's not annoying, I quite like that fact. I just don't think it's intended
 * Not only for SP.--XXErr4rXx

undefined If you use piston to break redstone signal that powers another piston, signal goes away but piston does not retract. (tested csp, cmp) 88.194.211.57

undefined If a piston connected to a rapid pulsar is destroyed, somtimes Block 34 (piston arm) remains until there is a block update. -S0221

undefined Monostable Circuits Set on 1 ticks output will release 1 tick, but set on 2 ticks will release 3 ticks.
 * Downgraded to minor bug. On the scale of all things minecraft, this is not a major problem :) --Mattrition 21:45, 12 April 2012 (UTC)

undefined There is a glitch where if the player makes an infinite loop using a piston, the piston will disappear after the loop made its first iteration. An invisible block (possibly air block) is left where the piston once was, but the piston can not work again unless replaced by another. When the player places a block on the invisible block, it is erased and the block isn't placed.

Annoyances a mp When you place redstone next to a closed trapdoor, open it, and destroy the redstone, the trapdoor will close. (tested on survival multiplayer, not creative/survival single player, or creative multiplayer. Fixed/Skipped

Blocks
Bugs F !cr The new way that pick block works gets many items that aren't in the creative menu, including:
 * Nether Portal
 * End Portal
 * End Portal Frame (should be added to creative inventory)
 * Piston arm (only if piston is extended) --Lolmaster 03:23, 6 April 2012 (UTC)
 * Monster Spawner
 * Cake (gives block (id 92) instead of item (id 354))
 * Nether Wart (gives block (115) instead of item (372))
 * Melon stems (gives a grey plant, the block ID being 105)
 * Pumpkin stems (same as above, except the ID is 104)
 * Wheat (gives block 59)
 * Enderdragon Egg
 * Stone with silverfish inside (should be added to creative inventory or at least given a name)

Tell me if there's any more NetherrackCreeper 22:24, 5 April 2012 (UTC)
 * Some blocks that are also affected are crops, nether wart, and melon/pumpkin stems. -S0221
 * Aside from technical blocks, this is not a problem as certain blocks are intentionally not in the Creative inventory. This allows Creative players with access to the items the ability to build structures with them, while preventing spoilers for players who have not yet reached certain points and preventing players on servers from using these items if the ops do not want them used. --Swampert rox 19:04, 10 April 2012 (UTC)
 * If what you're saying is the intention, then why not just organise the creative menu a bit better and add the blocks when the player gets the "The End" achievement. As for the servers you mentioned, that situation might call for a new command, something like "/itemdisable 120" or that mod API they're working on.

F !cr The pick block button doesn't give you the exact block for certain block types and tends to give the drop for the target block instead. Examples, and other incorrect behavior, are listed below.:

 * On lapis lazuli ore will yield an ink sac. Corensis 02:28, 5 April 2012 (UTC)

undefinedmp Blocks at layer 256 will not break in mp. This doesn't appear to happen in SP. Have been unable to test in survival mode.

undefinedmp When you want to break a ladder, your crosshairs will target the block BEHIND it. The way you remove the ladder is to get on the side, then hit it. undefined if a player is placing ladders and the block next to the ladder can contain a ladder, extra ladders will be placed in the second block. Frequently, the player will also be unable to directly interact with these ladders, only being able to remove them by breaking the block they are on.

undefined Transparent blocks, even if solid, don't affect items on the ground, sometimes hiding them completely and rendering them uncollected until the block or surrounding blocks are broken.

[X] When standing above water, breaking a block underwater does not show the breaking animation. (please format this section)

Annoyances a When standing on a ladder and destroying another ladder, actually we destroy the block on which the ladder is placed. There are many other situations where it is very difficult to break a ladder and it seems to depend strongly on the position of the player and the presence of other ladders nearby.

Gameplay
Bugs ! In Minecraft Pocket Edition, when you fly really high, you end up falling off of your world, and entering a white foggy place with nothing there, I was wondering if you could create an optional, random spawn point in the menu for the Pocket Edition as I have done quite a lot in this creative mode and really need to get it back. I think this is just a glitch.
 * I think this bug report belongs in the Pocket Edition Known Bugs page. NetherrackCreeper (talk) 18:18, 24 April 2012 (UTC)

! Sometimes when logging back in, in SMP your y (height) coordinate will not the the same as it was when you logged out. instead it will be the highest point with a solid block. for example if you were in a dungeon then you might end up on the surface. has happened 5-6 times in 1.2.5 and was also present in 1.2.x --86.52.2.125 01:15, 9 April 2012 (UTC)

x When the game searches for an existing portal (going from the Nether to the overworld), it doesn't seem to check above height 128. (Created a portal in the overworld at Y: 151, entered it, went back into the resulting portal in the nether, and ended up in a new portal at ground level)


 * Also, when creating additional neither portals in the overworld, they all return to the first portal generated (or perhaps most recent?) in the neither.--Cube3 22:29, 4 April 2012 (UTC)
 * You are incorrect. http://www.minecraftwiki.net/wiki/Nether_Portal#Linkage_between_Overworld_and_Nether
 * Yes we know what the intended behaviour is, but we are simply explaining what is actually happening. To recreate this, create a new creative mode world, build a neither portal over the old height limit (above the clouds), go through it and back. A new portal in the overworld is created. Next fly to somewhere far away, and build another neither portal (in the overworld). It will take you back to the first one generated in the neither.--Cube3 22:40, 9 April 2012 (UTC)
 * I did some additional testing. I have a over/nether portal pair that worked as expected. I created an overworld portal above 128 that lines up exactly on x/z with the nether portal (and for the sake of argument was < 128m away on the y axis. Using the > 128 overworld portal worked as expected. Using the Nether portal didn't connect me to the new >128 OR the old <128 portal. It created a brand new portal at ground level. Breaking the new portal and repeating would result in another new portal. Breaking the new portal and the >128 portal results in me being send to the original overworld portal again. --SeeJayEmm 17:04, 19 April 2012 (UTC)

undefined New fix of disallowing placing mushrooms under sky regardless of time of day and actual light level breaks use of giant mushrooms in overworld for farming/shelter/building smurf villages, etc. Darkness for mushrooms should allow for either 10 seconds of daylight before popping, or at least allow for planting at dawn/dusk & nighttime. If nothing else this kind of behavior change seems inconsistent with the proclaimed intentions of stability that was expected after official release. Other option to fix farming at least would be to un-nerf spreading and growth from the 5 per 9 limits.

undefined Occasionally the keyboard controls freezes (are ignored) mid-game. They remain frozen until any mouse input (left or right click) and will then work normally.

Annoyances a! If you have any Structure above you below y=64 the sky immediately turns black. Especially annoying and unavoidable on a superflat map. Building a house and looking out of the window - just pitch black darkness out there. Wandering under trees with fast graphics makes the sky flicker between black and normal. (Not sure if it's a bug.There's no scenario in which this would make sense. Even if I'm underground, if I see the sky, it's still blue.) Also happens in creative, so not related to the much more annoying and much less sense making void fog.
 * I have to second this.The Effect is called "Dimming".A server I play on requires a Mod which removes it together with the void fog (big buildings)

a Once entering a bed, the character will slide off and fall on the floor, but will sleep normally.
 * I think I see this too, and I think it's a bug. Try rotating the bed 90 degrees and see if you slide down it rather than fall out. I have one bed in one game where I fall out of bed (to the side) and another where I slide down the bed but otherwise sleep OK. Also try a room with a 3-high ceiling throughout.

 * If one were to attempt to eat from a stack of mushroom stew, one would eat the bowl along with the stew. This is why mushroom stew does not stack.
 * Nonsense. The empty bowls stack fine. There's no reason that eating from a stack of stew wouldn't have the same effect of dropping the empty bowl into a stack of empties as it does now.
 * Try putting water in one bowl, and put another bowl over it and press down in attempt to stack it. Guess what? The water makes way for the bowl! This is completely logical!
 * If you have no empty bowls, and your inventory is full, eating a mushroom stew off of a stack would attempt to add an empty bowl to your inventory but wouldn't have a place to do so. As long as stew does not stack, there will always be an empty inventory slot for the bowl to occupy (namely, the slot which had contained the stew). --timrem 17:56, 18 April 2012 (UTC)

 * This has been annoying me for a while. I'm pretty sure it started happening around 1.2.4 or 1.2.5. I keep about 25 dogs/wolves and 5 cats seated in a big room under my base in SMP. Usually while returning to the base (maybe when the unloaded chunks are loading?), they ALL suddenly warp to me.

Now I have to keep them all in one room (because they all end up there anyway) and having all of them suddenly warp to me at unpredictable intervals is annoying and dangerous.

 * 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 like a laggy teleporting player. However, they can also "jump" onto the top of the fence. While up there, they will spin around, and eventually come back down on the proper side. If the server is stopped while a farm animal is on the top of a fence post, then on server restart they ARE on top, not "tied" to the inside side of the pen, and after spinning around can walk off to the outside of the pen. I tried making fences at height 2 instead of height 1 .. Keybounce 08:24, 5 April 2012 (UTC)

Flagging as a major annoyance this time round because it really is starting to get on my nerves. They never shut up! Not when they're sitting, not at night when they should - mostly - be asleep, and if I turn the sound down to bearable levels I lose noises I do want to hear. 82.69.54.207 02:52, 19 April 2012 (UTC)

a! Dogs/Ocelots that are sitting will stand up and try to teleport to the player after the player has taken fall damage. They will wait for the player to teleport back to the same dimension before teleporting.
 * I been doing some tests, besides isolating my chicken flocks, it would appear that the pets are most apt to teleport from sitting position, not from fall damage but from environmental damage such as lava. --Autumnrain26
 * Has anyone tried this on a completely unmodded server/client? I know it sounds anal here, but the fact that the original bug reporter was playing on a server that had a "wilderness" map linked tells me that the server was modded and I want to make sure that this behaviour is correct for the vanilla server and client too. --Mattrition 08:44, 12 April 2012 (UTC)

a If you attack a passive mob (cow, sheep, pig) (particularly punching them, which doesn't hurt them much and gives you time to see what's happening) it panics and runs in a random direction. That random direction may include directly towards the source of the damage, which often allows you to keep punching it while it 'runs onto your fists'.82.69.54.207 22:08, 5 April 2012 (UTC)

Mobs
Bugs ! mp The spawning distance for Monster Spawners is two blocks off vertically in multiplayer. Even if the client shows flames in the spawner block you have to go up two more blocks for the Monster Spawner to actually spawn mobs. -Confirmed. JOWD

! mp If mobs are confined in a small area without any chance to leave, they often break out if the chunks get unloaded and then loaded again (relog,entering portals). This can be very annoying when collecting Mobs for XP farms or iron farms.

! mp Mobs do not spawn at a certain height is smp. Even with all chunks loaded mobs will not spawn. I'm unable to find the exact spawning height, however I do know that mobs will not spawn at 230+
 * Actually, it's 240. Or more accurately, mobs won't spawn within the highest 16 meter section that has at least one block in it. This is because the game tries to not spawn mobs above the highest section, but it uses the bottom of that section as the limit instead of the top. I'm not sure why that check is needed at all since mobs won't spawn in the air anyway. Last username 11:18, 11 April 2012 (UTC)

undefined Snow golems STILL do not leave snow on the ground, in biomes where they are supposed to: Plains, swamps, and mushroom lands. Thankfully, they no longer die in snow.

 * I think it was changed --Conscripta

undefined Slimes have slightly bigger hitboxes than their body.

undefined Mobs in chunks at the edge of the loaded area (i.e. in a chunk adjacent to chunk that is not loaded) are not updated. If the render distance is set to Normal or shorter, mobs can spawn in these chunks but never have the chance to despawn, leading to an accumulation of mobs in limbo. Since these mobs still count toward the total number of mobs, this results in a gradual drop-off in the number of "active" mobs unless the player continually moves around to change the loaded area. This is demonstrated in this video by Last_username. Phssthpok 17:08, 9 April 2012 (UTC)

undefined Iron Golems will appear to glitch through blocks if trapped in a hollow 6x6x6 cube filled with water, no matter how fast your computer is (probably, I tested this on a 16GB RAM computer).

undefined Mobs no longer spawn on bedrock, which alters bedrock's functionality in a way unintended by SMP server admins and makers of custom maps who build bedrock structures. This seems to be a violation of the previously established principle that hostile mobs could spawn on any fully solid block. FifthWhammy 15:28, 24 April 2012 (UTC)
 * Many custom maps have been broken by this change. I assume the change has been made to fix the bug with mobs spawning on top of the bedrock ceiling in the nether, but there has to be a better way to handle this without breaking custom maps. 87.63.85.30 16:04, 24 April 2012 (UTC)

Annoyances a In the Nether, mobs are not carried away by lava. That makes it impossible to build autonomous pigmen-collecting towers as can be done in the overworld with water. The only alternative is to use an impossible amount of redstone and pistons to push the mobs where wanted. But anyway, any flow of lava should carry mobs. Reported since 1.2.3.
 * I'm currently using 1.1 version (Due to some map editor cannot support Anvil yet.) and I found that lava flow does not affect even in 1.1. not just 1.2.3 and 1.2.5. Just want you to know. Kevin J Rattman 14:23, 11 April 2012 (UTC)

World generator
Bugs ! mp After converting my server world's block height limit (in Minecraft 1.2.3), all chunks had at least one type of block missing. The first one I found was a chunk with stone missing, and that also made floating sand, gravel and minecarts which I originally placed for transport. My server's town was about 2000 blocks by 2000 blocks large, and was entirely devastated by this bug. I started making a new town in a new world now. The old town map is still available in my server, so if you need pictures, just ask me.

! mp Spawn Location is reset to 0,50,0 after the first /stop command.
 * Create a new world with the server, invite players. If a player die, he will appear in the real spawn. (but looking in the level.dat with NBTEdit will show 0,50,0...)
 * Then, /stop, re-start the server, re-invite players. If a player die, he will appear somewhere around 0,50,0. So he will have to find where was the original spawn location, which is really annoying.
 * This has been fixed in CraftBukkit, so, to the Bukkit team : could you fix that, please ? =)

Graphical/Lighting
Bugs ! mp Glowstone sometimes doesn't light up chunks in SMP, allowing mobs to spawn in the area. Example: http://img215.imageshack.us/img215/1117/glowstonebug.png Walking into the dark area generally causes the light to update (but not always), but logging out and back in reverts it. The same chunks seem to be effected. Putting torches in the area works as a band-aid however. DarkWolff 01:46, 5 April 2012 (UTC)
 * That looks chunk aligned. Was that section made (lighting; placement of glowstones) prior to anvil, or after anvil? Keybounce 08:27, 5 April 2012 (UTC)
 * Yes, it is chunk aligned and yes the map was converted, though I extended the glowstone just pass the dark area in 1.2.1. I don't recall if I tried replacing blocks, but will try when I get home. I've mostly been putting down torches and removing them whenever there is a patch (been around since 1.2.1) to check if it was fixed. I've also seen similar bugs in other areas with lava, but never as bad as this. DarkWolff 15:23, 5 April 2012 (UTC)
 * Ok I tried replacing he glowstone and when I relog the area becomes dark again. Basically the glowstone will not light up the area in those chunks. DarkWolff 00:40, 6 April 2012 (UTC)
 * Foo. If it maintains after you replace the glowstone and force the lightmap to be updated, then it's not the issue I was thinking of. Keybounce 01:14, 6 April 2012 (UTC)
 * This is bug is also for Lamps as can seen here http://img836.imageshack.us/img836/7803/lampr.jpg This is after I've replaced Glowstone with Lamps because of having this issue.

! New lighting system severely drains FPS since 1.2. This problem persists in 1.2.5. Lighting changes in-game caused by lava, redstone lamps, redstone repeaters, and/or pistons cause heavy FPS drops and/or stuttering on low- to mid-range computers. This problem didn't exist in any version prior to 1.2. It looks as though there is now a lot of excess load on clients to calculate lighting changes, whereas pre 1.2 Minecraft forced the server to deal with lighting calculations. This essentially makes the nether and busy piston/redstone contraptions unplayable as the FPS lag is extreme. d3fin3d
 * Should this be updated to a minor bug? d3fin3d
 * If the result is that the game is unplayable on computers that meet the game's minimum requirements, then yes, I'd call it a bug. Keybounce 08:30, 5 April 2012 (UTC)


 * Unfortunately, even with 4GB of RAM allocated to java, and thus minecraft, this lighting memory decay issue causes me to place blocks twice. It is not a mouse problem, but an FPS issue. Even though I can play more graphically intensive games. This issue is occurring in offline mode. SoaringMoon 11:17, 13 April 2012 (UTC)

! As of 1.2, there are consistent unrendered chunks as there were prior to 1.8 or 1.9 beta. These unrendered chunks show up in random spaces and can appear in a chunk when returning to an area when they hadn't been there the previous time through, even though the user has not logged off of the game. When a user tries to walk over these areas, they will get stuck or fall out of the world. The user can safely ride a minecart or a boat through the chunk from one side to the other, although both the minecart and the boat will appear to turn slightly off of the direction they are going and tilt to the side a little. This is a client side issue as one person will see the unrendered chunk but another person will not when on MP. Logging out of the game in play and back in (but not closing the client) will usually fix the local render issue but not eliminate them all together. This happens on vanilla servers and clients as well as clients with texture packs in place. Examples: http://dl.dropbox.com/u/2274101/2012-04-07_10.29.14.png, http://dl.dropbox.com/u/2274101/2012-04-07_10.29.21.png, and http://dl.dropbox.com/u/2274101/2012-04-07_10.29.40.png.

! Sometimes when you remove/place a block the graphics will not update. This causes blocks you place to be invisible, blocks you remove to look like they are still there and doors/trapdoors you open to look like they are closed. This only happens in certain chunks. Restarting Minecraft fixes the problem, but it soon reappears in other chunks. If you place a torch where the bug is active the light will still spread in the parts that work normally and vice versa. I am only able to reproduce this bug on one particular computer (out of two I tested on) with Windows XP (the other has Mac OS 10.7) but I have seen it happen in a let's play on Youtube.
