!!mp Unknown server-stopper. After about 20h running, the dedicated server started consuming all available CPU from a single core, all the allocated RAM (full red bars on graph too) and displayed an average tickrate of 1100 ms, at least 22x slower than normal (50 ms). All players were disconnected with endOfStream and the server repeatedly dumped overloaded warnings on the console. Further debugging is unavailable, will do on next occurrence. a Stop command took around 5 minutes to complete, with a tickrate of 500ms with no players online. After starting it back, everything works fine. Configuration: AthlonIIx2 x64 Win7 2GB DDR2, 1GB allocated, Java 7 update 4. Dedicated machine, average of 2 players online. It has happened three times so far, identical symptoms with variable tickrate lag. One time, the tickrate kept high enough for players not to drop, but low enough for them to yell 'LAG' at me. Survival server, no operators, unmonitored remote machine. --Steve G. Wood 22:30, 13 July 2012 (UTC)
 * It happened again. Here is a screenshot: [[Media:Screenshot_1.png]]

And profiler results. Notice there are no players online at the time of profiling. undefined

!! What appears to be a memory leak in the chunk loading portion of the code. Without allocating more memory to Minecraft, Java Platform SE Binory will crash in around 10 minutes of straight traveling, particularly in the nether. Allocating 2 GB to Minecraft, memory usage for java is seen jumping to 800 MB at world load and steadily climbing beyond 1.8 GB and Minecraft showing 700 - 900 MB in debug screen. 1.2.5 version caps off around 1 GB for java and 300 - 450 MB in Minecraft debug screen. This was found with java 7 update 5 64-bit, windows 7 64-bit, 6GB memory, GTX 670 graphics card, i5 650 3.2 GHz, minecraft settings set to fast graphics, no smooth lighting, no clouds, no server textures, all other settings at their default, tested on all render distances without any noticeable difference

!In some computers (1.75 GB of RAM, 32-bit, 2.71 GHz, Windows XP SP3, Java 1.6) the world will still not save blocks, but will save player configuration. Example seen here http://imgur.com/a/xixYo#0 (1st and 2nd screenshot taken in a run, the 3rd one is after reloading the world). Here's a debug profile made while placing the blocks, if it helps. --Manuelschi 17:06, 5 July 2012 (UTC) undefined

!mp Players falling through world and getting socket exception when connecting or going through nether gates. Reverted to 26 and I was fine. Moved back to the spawn (my base is some ways away) and updated to 27 and everything is fine. Went back to my base and re-logged and it happens again. We were able to teleport me to the spawn and I was fine. Had someone else come to my base and re-log and he gets the same exception. I have also experienced this when travelling from the nether to a portal at this base.I have completely re-installed minecraft and java. I started a single player creative on the same seed and went to the coordinates and was able to exit and re-enter. seed: ubik rough coordinates: x = 1473, z = -155 --Neema 00:37, 7 July 2012 (UTC) undefined
 * I can confirm this bug. I'm also getting "Internal Server Error" while in the nether, and getting booted. --SullyTheUnusual 15:58, 7 July 2012 (UTC)
 * While I personally have not experienced these "Socket Exceptions" of which you speak, I have experienced falling through unloaded chunks into the Void after using a portal before the game loads the chunks and puts me back in the portal. TorchicBlaziken 23:59, 7 July 2012 (UTC)

Annoyances a! Every time I try to update Minecraft through the launcher it stops at about 5-9% percent downloaded (I've checked the minecraft.jar, only metainf folder was there). --66.219.226.219 22:03, 7 July 2012 (UTC)
 * Are you sure you are using a bought account? This page is not for cracked Minecraft.  07:23, 8 July 2012 (UTC)

 * no, that didn't work either... --66.219.226.219 16:12, 9 July 2012 (UTC)
 * I have this too, and it is the most annoying thing ever. I tried completely disabling antivirus/firewall and still, nothing happens.
 * I have tried every thing I can think of and still nothing works, I re installed java, restarted my computer, and completely emptied .minecraft and it still won't work, can some one please tell me whats going on here. --66.219.226.219 17:12, 13 July 2012 (UTC)
 * A few steps you can do to ensure likelihood of everything going properly. Make sure Java.exe and Javaw.exe are allowed through your firewall, as well as Minecraft.exe. Go to the web version, make sure you tick Trust, etcetera. If it works on the website, it should work on the exe version once you've gotten those files. If you are still having issues, download LWJGL, and put the appropriate files in your .bin directory. I'm not going to link to it, Google is your friend, yeah? --Debugman18
 * Try to go back to the latest snapshot and change your language to the default, English (U.S.). I had a very similar problem when I changed my language to Australian English and then tried to revert to 1.2.5 using the 'Force Update' in the launcher.  After I re-installed the snapshot Minecraft would work again and I used that to change my language to English (U.S.) and then I was able to successfully revert to 1.2.5. 58.164.232.134 08:07, 20 July 2012 (UTC)

aOther chat key-bindings are incorrect for Mac OS X. Fn+Arrow Key (Home, End, Page Down/Up) should have no effect on the cursor. Ctrl+Left/Right should instead be Opt/Alt+Left/Right, Cmd+Left/Right should equate to Fn+Left/Right and Cmd+A should select all text instead of Ctrl+A. Jrtc27 13:37, 10 July 2012 (UTC)

a Still cannot quit Minecraft using the standard shortcut Cmd+Q. You can quit it before logging in through the launcher however. Bug has been present in all versions of Minecraft and ought to be fixed. Mac OS X

a When trying to connect to an incompatible minecraft server, such as 1.2.5, I get the very unhelpful error message "Internal exception: java.net.SocketException: Connection reset". It would be nice if there were a more descriptive error message, saying what the server and client versions are, and explaining that they are incompatible. Thue 22:32, 10 July 2012 (UTC)
 * If a server/client is out of date it will tell you. Not sure what you are talking about.

Fixed/Skipped

f If you try to spawn a entity that is not a mob via spawner editing i.e. cart or boat the game will crash

undefined

--SoaringChris137 21:31, 5 July 2012 (UTC)
 * Spawner egg or mob spawner? Either way, the game is not supposed to give you the chance to do that. It's like trying to use a spawner egg to spawn an item entity, it will crash. Since it cannot be reproduced on vanilla minecraft without 3rd party programs i vote for deletion.--Manuelschi 22:53, 5 July 2012 (UTC)
 * It was a spawner block, like you find in dungeons, and because in the previous snapshot the special spawner permissions were added but only accessible through 3rd party editing I don't think this can be overlooked. --SoaringChris137 23:26, 5 July 2012 (UTC)
 * This has been fixed, but I really wouldn't call this a critical bug. It's custom behaviour that we've never supported before or had intentions of directly supporting. Dinnerbone 08:16, 6 July 2012 (UTC)

fmp Every user that logs into my SMP server gets kicked off immediately, with the following message in the console (no crash report recorded on server nor client): --Inertia undefined
 * This may be caused by 'view-distance' in the server.properties file being set above the default value of 10. --Recondite 20:32, 5 July 2012 (UTC)
 * Good call. Indeed, it was the view-distance.  I had it set to 15, but taking it back to the default (10) seems to have fixed it.  But in the previous build, having it set to 15 seemed fine. --Inertia
 * I have view-distance set to 10 but some players joining my server are still getting kicked out with the reason being disconnect.overflow. I had never seen this error before 12w26a. For me, it is happening in 12w26a and 12w27a while never happening once in 1.2.5. I have not used any snapshots between 1.2.5 and 12w26a so I cannot comment about those. You are mad 16:04, 14 July 2012 (UTC)
 * I think this problem appears, when a player is on a high position and leaves the server. The player can not join until the player dat file is deleted. --TrustableDigger 19:24, 14 July 2012 (UTC)

f CMD-V does not work to paste things into Minecraft. Dinnerbone said he was having trouble with this because he didn't have a Mac. However, Minecraft recognizes the CMD keys as LWIN and RWIN in the controls menu, so enabling the LWIN-V and RWIN-V combinations to paste might do it. CTRL-V does work on a Mac, but it is unintuitive for Mac users. TorchicBlaziken 21:14, 28 June 2012 (UTC)
 * Potentially fixed, need a mac-y person to test it in the office. — [[Image:Mojang_AB_logo.png|13px]] Dinnerbone(T) 08:28, 9 July 2012 (UTC)

f My SMP server uses 60% CPU when no users are logged in. The 1.2.5 server used 40%. AFAIK, there is no good reason why it should use any amount of CPU when nobody is logged in. My server uses much more electricity than neccesary because of this. Thue 15:50, 5 July 2012 (UTC)
 * I'm running two servers on mac at the same time, getting a 2% CPU usage when noone logged in, it gets up to 50% when I log in from my computer (so, 2 Minecraft Servers + Minecraft Client). I usually got al least 75% usage on previous versions (same 2% when no one logged in). iMac 21.5 late 2010, 8 GB RAM (1 GB assigned to every server, and 2GB assigned to Minecraft client). --Asmcsl 17:03, 5 July 2012 (UTC)
 * I have a relatively old Athlon64 X2 3800+, but still shouldn't be using 40% or 60%. Perhaps you have killed your enderdragon and destroyed your end healers, which seems to be what is using lots of CPU in 1.2.5 (From profiling the partially decompiled 1.2.5 source code from bukkit. A 24x24 are is always loaded in each of the three worlds). Thue 00:29, 8 July 2012 (UTC)
 * Now, after running a good deal of time, it actually seems to have settled down to run at ~6% CPU, which is obviously much better than in 1.2.5. Don't know why. It woul still be nice if it didn't use any CPU when nobody was connected, of course, like fx my apache and sshd servers. Thue 00:34, 8 July 2012 (UTC
 * Running 12w27a on an Arch Linux i3 with 4 gigs of RAM I haven't had any issues with CPU load. Minecraft is using about 3.9% CPU when noone's logged in which is high for a program that's doing nothing, but isn't high for Minecraft. ArcherSeven 05:33, 8 July 2012 (UTC)
 * I decided that it's silly to tick entities when nobody is around to hear them fall. CPU usage should greatly improve now. — [[Image:Mojang_AB_logo.png|13px]] Dinnerbone(T) 09:48, 9 July 2012 (UTC)

undefined cr If you throw eggs REALLY fast while standing still, the throw origin will shift. Anything thrown after that will come from the shifted position. Moving will reset the origin. Screen: [[media:throworiginerror.png]] --Steve G. Wood 06:38, 20 July 2012 (UTC)
 * But you are throwing splash potions, not eggs !? Does this issue occur when throwing anything ? --80.134.11.175 07:38, 20 July 2012 (UTC)
 * Only eggs trigger the glitch, but after it's triggered anything that can be thrown will be glitchy, even more eggs. Also, the longer you force throwing eggs, the further the origin will displace. Notice that this huge distance was triggered by using a fast clicker app, but human clicking can make this error aswell. --Steve G. Wood 02:11, 21 July 2012 (UTC)

! Hardcore levels get deleted if you try to skip the end credits. I opened up a hardcore world that I beat in 1.2.5 and went back to the end. When I left, I was presented with the credits again, and hit esc to skip them. The game said that I was disconnected because I died and deleted my world. Ryan392 02:26, 12 July 2012 (UTC)

! When creating a map in creative mode via a workbench and shift clicking to your inventory it will always be Map_0, click and dragging works normally though.
 * That's a feature, that allows to make maps with same id. I suggest this feature removed, and duplicate will be made when upper left corner contains map to be cloned, at work bench. Map will stay, other materials removed normally. Map must count as there were 64 of them, when calculating how many can be created. 93.106.164.34 13:50, 18 July 2012 (UTC)

! NPC Villages will lag my computer down to <1 FPS. I don't know what's causing the problem but this has never happened before and I have to delete my [Player].dat file to respawn and the lag stops. I cannot produce a debug profiling due to major lag. Will list specs if needed. Zmr333 01:58, 7 July 2012 (UTC)
 * Not a crash bug. Downgrading and moving. --Mattrition 15:25, 7 July 2012 (UTC)
 * Unable to reproduce. I tried my personal SSP world with a medium village, and also a Superflat world on Creative with multiple very large villages. I did not lag at all. --Fperson1 05:12, 9 July 2012 (UTC)

!mp Player 1 can push Player 2 around on their screen but Player 2 doesn't move on their screen. Therefore Player 1 can push Player 2 in lava and Player 2 will take unnecessary damage.  QuAd205 ( T 20:45, 19 July 2012 (UTC)
 * I've had this happening too. Seems to glitch with any entity pushing the player. I was shot by a few skeleton arrows and walked around to hit them but saw them firing at a wall while I got hurt. Done using the minecraftserver.exe Lukesoccer21 05:42, 6 July 2012 (UTC)
 * Happens for me too, though I've noticed it seems a bit inconsistent. I've been able to push a friend and when they move, they notice they're suddenly elsewhere as described above, other times I've pushed them, then when they moved they've gone back to where they originally were as if they hadn't been pushed at all. -TheWyo 20:01, 6 July 2012 (UTC)
 * Similar to the bug described above, this issue is very apparent when player 1 is not moving in a boat and player 2 pushes player 1. Player 1's location looks unchanged on his screen but is in actual location on player 2's screen. Player 1's movements are affected by blocks and positioning based on player 2's screen. Location syncing issue is resolved when boat is left.
 * This happens with many other kinds of movement that is not caused by the moved player, for example pistons. Redstonehelper 11:55, 16 July 2012 (UTC)

! When water current pushes you into a corner, you start taking damage. Screenshot: http://i.imgur.com/uzMEc.png (Note: this screenshot was taken in Peaceful mode.) --Techokami 19:32, 6 July 2012 (UTC)
 * seems related to the "Player 1 can push Player 2" Bug stated above. Something's wrong with the client and server not matching up. Was this done on a server or "singleplayer"? --Lukesoccer21 17:17, 7 July 2012 (UTC)
 * It was done in "singleplayer". As long as there are blocks at the head level forming a corner, and a diagonal current pushing the player into said corner, the player takes damage. The game probably thinks the player is inside the blocks and is suffocating. --Techokami 22:16, 7 July 2012 (UTC)
 * This occurs from all sources pushing you, IE if a mob pushes you into a corner.BlackDragonIV 16:24, 10 July 2012 (UTC)
 * I can confirm this. Players die very often on my snapshot server from suffocating in walls, and blame each other out of doubt. --Steve G. Wood 12:38, 11 July 2012 (UTC)
 * Happens a lot when villagers are crowded in a room (they do seem to love sharing rooms) and you are pushed into a corner. --5thHorseman 00:24, 12 July 2012 (UTC)
 * This happens to me all the time in "single" player. It is extraordinarily annoying, to say the least. --Basilo1146 21:52, 14 July 2012 (UTC)

! Occasionally your character can seem to "teleport" when fighting a water current. For example, if one is underground mining obsidian whilst fighting a water current, you will appear to be breaking the obsidian (complete with cracking animation and mining sound) and suddenly appear upwards of 7 blocks away, at the end of the water current. Used major bug tag because it is fully possible to be pushed into lava in situations such as the above example, or if working on a mob grinder, or into a corner triggering the above bug. This happens in SSP, not sure about multiplayer. --Fperson1 01:01, 9 July 2012 (UTC)

! Sometimes, you get random suffocation damage, most times when sprinting. 189.34.246.216 14:53, 10 July 2012 (UTC)

undefinedcr (seen on MP) After flying for some time in Creative mode with some drops, switching to Survival 7 blocks above the ground caused an instant death from fall damage. It seems the fall damage from all the flying was accumulated. --Steve G. Wood 02:10, 18 July 2012 (UTC)
 * Retested, was able to reproduce. --Steve G. Wood 02:29, 18 July 2012 (UTC)
 * Confirmed on my end as well QuickAluminum 19:15, 18 July 2012 (UTC)

undefined mp Using a tnt launcher, the player will hit a bump, fall down and then shoot up again. -- Mustek 14:29, 5 July 2012 (UTC)
 * (moved from Mobs, NPCs & Animals) Cannot reproduce. I used this cannon: http://www.youtube.com/watch?v=V3WqdVpK7-8&feature=plcp on a dedicated server and it fired just fine. Strangely, the TNT on the rightmost barrel vanished with no trace when activated. Like if it hit an entity limit when activating all that TNT at once. The cannon shot wasn't nearly half as powerful as in SP (video). --Steve G. Wood 02:29, 18 July 2012 (UTC)

undefined Flowing water doesnt push primed tnt like it used to in 1.0.0, making tnt cannons and player launchers not work properly Gravemind2401 01:55, 18 July 2012 (UTC)
 * It aslo doesnt behave in a "real" way anymore by spreading out over a surface. It instead flows the shortest path downhill, ignoring everything else. Screenshot Note that there were no solid blocks surrounding the source blocks that were then deleted. The landscape was as-is when placed.--QuickAluminum 13:01, 18 July 2012 (UTC)
 * That's the way water's worked for a long time and is intended. Within X block (I think 3) water heads right to the dropoff. If you place a bucket on a flat surface, it'll still spread. --5thHorseman 03:34, 19 July 2012 (UTC)

undefined Since the newest snapshots, fall damage was reduced by one block, such that falling from 4 blocks won't hurt you. Problem is, very rarely you do take damage from 4 blocks. --Steve G. Wood 18:49, 13 July 2012 (UTC)

undefined Logging out and logging back in while falling off a cliff will only make you take the fall damage from the height you logged back in from. It is extremely annoying with fall traps on PvP servers.

undefinedcr Crafting something in Creative Mode (I know, why should I...) in the 2x2 crafting field generates the crafted item and drops the old items like they were not used after closing the menu. I made four sticks with two pieces of wooden blanks in this Screenshot. Doesn't occur in Survival Mode. --Freakedenough 18:49, 5 July 2012 (UTC)

undefined With some bed placements, you fall out of the bed instead of sleeping in the bed. See File:Falloutofbed.png to reproduce this. Seems like some part of the game code still thinks the player is standing, so it's trying to prevent him from suffocating by pushing him away in some direction. -- JonHa97 18:44, 5 July 2012 (UTC)
 * I believe it is related, but while on a long field sortie for some wood, I could sleep on a high beacon with nothing but sky overhead, a little worried that I would get stuck in a death loop by coming out of it in mid-air, but fortunately that didn't happen (on a 1x3 platform) way up in the sky. I never came out on the bed, but on the empty spot (always near the head of the bed due to placement dynamics) Later, I built a tiny soddie on the ground with a 1x3 interior and a 3 unit high ceiling. I came out of sleep outside the building.  Not sure if it's related, but you can sleep in a bed underwater in MCXBLA 1.6 video. -- Featherwinglove 15:58, 21 July 2012 (UTC)

undefined Eggs thrown by dispensers will sometimes spawn chickens in a block. The chicken will suffocate and die. Other eggs function normally. ~Cm283 20:21, 5 July 2012 (UTC)

undefined Chests do not update properly. Placing items in them, or taking items out of them may fail. Ex. you shift-click a stack of dirt into a chest, it appears in the chest. If you leave the chest and click the inventory slot the dirt was in, it re-appears in your inventory - it seems, it has never been placed in the chest. Also, the chest closing or opening sound and/or animation may not play. --77.189.31.93 23:23, 7 July 2012 (UTC)

undefined Surrounding a bed with slabs still works when sleeping; you wake up on top of the bed, as expected. However, when dying, the game thinks the "home bed was missing or obstructed". --Steve G. Wood 18:32, 11 July 2012 (UTC)

undefined sp When in Survival in singleplayer, if you open the world to LAN with Creative on for the people that join, you can log into the game again in a different client with the game that you opened to LAN unclosed, go into the LAN server, have it kick you because you were logged in twice, and then when you open the world again, even though it still says survival, you are in creative when you enter the world. I found this the other day in the last snapshot, and today I found out that it worked in 12w27a. I'm sure that some other people would not mind this bug, but it does not make me too happy. I have not yet tested if you can also go back from creative to survival. --Agent A 21:29, 11 July 2012 (UTC)

! mp When Player1, who is in the Nether, tries to teleport to Player2, who is in the overworld, Player1 stays in the Nether but gets teleported to Player2's coordinates, thus possibly causing suffocation, or death from lava/fire. It is not possible to stay alive when you suffocate this way; unless you know a safe position where you can teleport, or a random guess saves you. –nyuszika7h

undefinedOpen to LAN thinks it knows the local LAN address. In particular, it wants to use 192.168.x.y (Local wire) in preference to 5.23.x.y (Hamachi). This prevents the use of Hamachi LAN's. --Keybounce 23:52, 17 July 2012 (UTC)
 * Well, there's way around that. 1. Make sure minecraft is closed. 2. Disable your network connection (this can be done through windows or plugin cable off from back of your computer). 3. Start minecraft, load your world, open for lan. 4. Re-enable your network connection (so hamachi and your connection is functional again). --194.197.134.190 08:49, 22 July 2012 (UTC)

undefined Redstone timing errors in 27a and 125 multiplayer that works just fine in 125 single player.

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 125 single player, it works perfectly. In 125 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.)

Annoyances

a! I've noticed that in this version the whole game world "freezes" on the server when the player is far (about double distance of view in Far mode or a little more) from the objects like furnaces, saplings, melons, growing wheats.. When the player is not near, the furnaces do not cook, trees, melons and wheat does not grow. Even minecarts with furnaces do not push other carts when the player is not near (If the player travels with minecart with powered rails and leaves behind the cargo train with furnace, the furnace cart stops moving, because waiting for it at the station takes forever. It looks like you have to watch everything to make it happen, because when you get closer to the cart with furnace, it moves again. For example if I leave a lot of furnaces to cook in one village and go for about 1km (1000 block distance) when I come back later (even after 30mins) I find that only few items are cooked in the furnaces. This kind of "freeze" is when only none of the players are in that location around (leaving village empty makes everything stop there).
 * This is by design. No computer has enough processing power to simulate an entire world, therefore all sorts of things that 'ought' to keep working unattended will freeze if there are no humans nearby to observe. Plant growth, smelting, and the movement of distant mobs and entities are just the three most obvious areas affected. (Note that the definition of 'nearby' does vary a bit from one part of the game to another.) --82.69.54.207 00:50, 18 July 2012 (UTC)
 * Additionally it's worth to note that this behaviour is not specfific to snapshot 12w27a, it is since the very first days of Minecraft. Read Chunk for more information. --Kumasasa 05:58, 18 July 2012 (UTC)
 * While this has been a known aspect of Minecraft since the game was first created, I'd still call it an "annoyance", and thus a valid complaint. "Processing power" is not a preventative issue for certain items in the game world. If you imagine that chunks are saved when they're unloaded, but the game-time they're unloaded at is saved with the chunk. When the chunk is reloaded, the game does simple subtraction (current time minus the time the chunk was saved) to see how much time has passed. Furnaces at the very least could then advance through their current "cooking" cycles according to how much time has supposedly passed. I'd imagine smelting a bunch of iron ore into ingots in one single calculation would actually be less strain on the server than constantly cycling through them one at a time slowly. Grass growth would also be relatively simple, though might look a little weird at chunk borders. Other items such as vine growth, fire, and physics objects might also be "sped up" in an "anti-bullet-time" fashion, possibly. Probably just prior to the chunk becoming visible to the player.

a! sp (Might happen in MP as well) I commonly have the problem of the keyboard becoming non-responsive while playing. A quick, double alt-tab fixes the problem, but i dont know why. It can happen at any time, when a game is just loading, or after the game has been running for a while; both are equally common.
 * You can comprove by creating a world that contains a lava pool in an tree biome, you never has get close to it, being the pool alone in the world, then after 10 Minecraft days I went to explore and fount out that no trees was burned, it seems to doesn't simulate things too far.

a! When extending 4 pistons around a lava source block in the middle, all the pistons extend, but one or more also appear to be retracted at the same time.

a! mp Every time I Log in or respawn, I will appear to be falling though the world in darkness, Less frequently I will appear with a block (normally stone) right up in my face. This happens for 5 to 20 seconds before I regain full control and can see and interact with the world. While falling I can look around with my mouse freely. I can also type but nothing happens when I send message. Suddenly I will appear in the game in the correct spawn location. All my chat messages will rapidly send in quick section. I have only tested this on one server. It is only played on by me and my friend. He doesn't encounter this bug at all, yet I do every time. He hosts the server at his house which is only a small media server not intended for this kinda use really perhaps, Although when the server was running 1.2.5 and previous versions I encountered no problems like this. The problem doesn't occur for me in single player. --Noac 17:03, 10 July 2012 (UTC)

a When you die, and respawn (no beds involved), you are teleported to the highest point of the spawn region. This makes it hard for custom map makers to create indoor maps without players getting out of the map when they die.

a LAN visitors join where you are. Not at spawn. Or even where you wanted them to. If the LAN visitor disconnects, and you return to spawn, or wherever you wanted them, on reconnect they are not moved to you, but are left where they logged out.

Work-around: Delete the player file.

(To clarify: A LAN visitor's spawn point is near where you are when they join. There is no way to specify "Join here". If you go wandering off, they may be no where near your main build. This only affects their first time on your world, and then their location is "remembered".)

a Open to LAN wants to keep the host up, tying up the graphics card. Even if the window is hidden, in pause/escape mode, or otherwise not doing anything (waiting for friends to arrive), the GPU is busy and less available for other programs.

f Any blocks above Y=191 when logging into a single player world become invisible. Logging out on a structure above this level on SSP made me unable to move, place blocks, or break blocks because I was glitched into invisible blocks. --68.33.111.198 16:08, 5 July 2012 (UTC)

 * Occurs for me as well. Can produce screenshots if need be. Also, the blocks seem to reappear upon a block update; the structure that disappeared for me was a farm so when farmed soil became wet farmed soil, it showed up. When melons grew, they showed up. Placing a block on the newly appeared blocks causes it to turn into whatever block is actually there (making the old block visible). Exiting the game and returning makes all blocks invisible again. -Bleaker 01:14, 6 July 2012 (UTC)
 * This happened to me in the Nether. I thought I screwed something up in MCEdit. I couldn't interact with the blocks, but they stopped my motion.

s In a fairly recently made world, I tp'd a short distance from the Far Lands. First, I noticed torch particles are pretty far from the torch. Secondly, it is possible to place a torch on the invisible wall that marks the edge of the map. This can be reproduced by placing a torch on the last block in bounds, then right clicking to place a torch on that torch. This will put a torch on the invisible wall of the far lands. --Keithicus420 06:03, 8 July 2012 (UTC)
 * The torch particle thing is a known mechanism of proximity to the Far Lands, as I recall. As for placing torches on the invisible wall, I think it relates to placing torches on glass or similar, though I don't really know about that. --Fperson1 05:23, 9 July 2012 (UTC)

 * This is almost certainly an unavoidable problem related to floating point loss of precision. Since this distance from the world origin can't be reached by in-game means, it is not a big deal.

n When right clicking a minecart with furnace the minecart moves foward on the track. You cannot access the furnace to place wood or coal --Kain837
 * This is how it has always been? You hold the fuel in your hand and right-click to add one of said fuel item into the powered minecart. This will cause it to run until the fuel is depleted. You can't drop in an entire stack at once. --Techokami 01:42, 7 July 2012 (UTC)
 * oops, your are right about dropping a whole stack in, but if you hand is empty and you right click the cart will move 1 block forward on its on, no coal was placed in the furance --Kain837
 * I can confirm this (I remeber observing this event back in 1.2.5 as well). It does happen in survival mode (and I am sure is a bug in said mode) but were you in creative when it happened? It is intentional in creative, but it is supposed to act like you put a piece of coal in the furnace (and move much further than one block), whereas in survival this isn't supposed to happen at all.--Marioman66 01:38, 9 July 2012 (UTC)

 * I think this is intentional. Even if you need 30 levels to enchant it, you still won't get the best enchantment. I think the more books you have, you get a greater chance of getting more high level enchantments, regardless of you using 30 levels. --Autofire 18:39, 8 July 2012 (UTC)
 * Can somebody confirm this mechanism? --velvetpro 19:45, 8 July 2012 (UTC)
 * This is an intended feature. It was explicitly stated that the maximum enchantment level is now 30, and it only takes ~15 bookshelves to get to. Also, the amount of bookshelves you have does not affect the actual enchantments directly, only changing the maximum possible level. More than 15-16 bookshelves does not increase the chance of getting more or better enchantments. --Fperson1 05:23, 9 July 2012 (UTC)

n Not sure if this is supposed to happen, but I managed to get a tripwire to trigger with the only thing intersecting the wire being a dropped redstone torch. This occurred when I destroyed the block the redstone torch was on in creative mode, causing it to drop onto the wire and activate it. The circuit was not previously being affected by the presence of the redstone before block deletion so I am certain it is related to the dropped redstone torch intersecting the wire. This might be intended but I'm fairly sure it's not intended. Pharap 16:54, 9 July 2012 (UTC)
 * It's intended. From the wiki: "To activate a Tripwire when it is connected, an entity (mobs, minecarts, boats, arrows, items, etc.) must move on, through or over it." dropped items (like your torch) are entities. --5thHorseman 23:01, 9 July 2012 (UTC)

Blocks
Bugs

undefined sp Sugar cane placed on farmland that has been just untilled by jumping on it will rehoe the block back into farmland (sugar cane is not placed, or appears momentarily, as consistent with normal merge lag.) I tend to combine sugar cane and wheat farms by making a 2x2 cistern and planting sugar cane in the first adjacent blocks (eight total) and the rest of a 10x10 plot with wheat (88 blocks). In this case, I knocked out the four corners of farmland for torch cairns (a cobble block with a torch on top, the dirt level the farmland is on remains in place; wheat remaining: 84 blocks.) Walking away about 300m and returning makes the now dirt block respond properly. I remember this responding properly in 1.2.5. Further testing underway (I will not be testing it in multiplayer.) -- Featherwinglove 15:50, 20 July 2012 (UTC)
 * Testing update
 * Bug does not appear to be affected by whether the farmland just untilled is hydrated
 * Bug is possibly affected by duration after farmland is first tilled (i.e. sugar cane plants if farmland is tilled and then immediately untilled, it will hoe if the farmland has been in place a minute or two; this is what led me to test for hydration. After further testing, I have not found this effect to be consistently repeatable.)
 * Bug is affected by duration after farmland is broken (i.e. sugar cane plants if the farmland has been dirt for a minute or two.)
 * Running about 300m away and back retilled a broken farmland block before I attempted to plant sugar cane on the dirt block (meaning it may not be directly related to the sugar cane.) Both a farmland (with wheat growing on it) and a dirt (with sugar cane growing on it) were adjacent to this block.  Immediately after this, an attempt to break the farmland and plant sugar cane succeeded.
 * Bug is not affected by the distance of the character while placing sugar cane (i.e. whether he is standing on the spot or not or if he's 2m away.)
 * Bug is affected by whether the broken farmland had sprouts on it when broken: Sugar cane plants if it did, but will not plant if it did not. I have not yet had an exception to this rule (but I'm running out of seeds; each use of this method uses a seed.  Other than that, it appears to be an effective workaround.) -- Featherwinglove 16:17, 20 July 2012 (UTC)
 * I had one occurrence with a cobblestone block. The dirt I was placing it on reverted to empty farmland. On further testing, the bug did not recur as expected with cobble or any other type of block. I searched for a correlation between whether a farm block had previously hosted wheat and found a weak one suggesting that older farm blocks are more susceptible.
 * I have only had this bug occur adjacent to water, but this now includes diagonal adjacent, where you can't plant sugar cane. I suspect this bug can occur with all materials and distances from water, and will test other situations to see if this is the case. I'll test dry farms if I do have it occur away from water.
 * Is it possible that this bug may be caused by the server, client, or world data thinking that there is a crop above the block? -- Featherwinglove 23:56, 20 July 2012 (UTC)

undefined sp If sand is falling while the player is dead the sand will be black if you respawn and go back to the sand. If you destroy all the black sand blocks there will sometimes be some sand ghosts left, you can walk throught some of them, and some you can't, you can't break them too and if you break the block under it the sand ghost will fall. This happens with gravel and dragon eggs too(dragon eggs will not be black). You need to rejoin the world to fix this. I found this bug when I was blowen up by a creeper in a sand cave and went back to the cave. --Swekob 12:18, July 18, 2012

! Pistons, set on a rapid delay, glitch out - Sometimes it is possible to create phantom blocks with the same properties as a normal block, but the phantom block doesn't drop anything when broken. When walking to a piston set on a rapid delay (see video), you will go up & down, shifting will make you go up even higher. Sometimes there is no sound when breaking a block in that contraption. See this video, it explains those bugs better. NiceMark 18:52, 8 July 2012 (UTC)

! Look straight down, jump and try to place a block. Sometimes it works, sometimes the block appears and then disappears. The previous snapshot did not have this issue. --Croftyraider 17:05, 6 July 2012 (UTC)
 * I've seen this a lot with peaceful mobs (It would probably happen with hostiles too but they're - you know - hostile) nearby. It's like the client thinks it's OK to place the block (and it looks so to me as well) but the server is a tiny bit ahead of me so it sees that the mob has walked within the bounding box. I imagine it's similar when you're jumping. By the time the server sees that you want to place the block, you're already coming down. --5thHorseman 20:50, 6 July 2012 (UTC)
 * I have the same. When you manually click each block in good time, it is better. But this is a bug ofcourse. --velvetpro 21:40, 7 July 2012 (UTC)

 * (Merged duplicate) Since the merge, "pillaring" is almost impossible due to the server and client being off a little. Every time you jump and place a block under you, the game thinks you were occupying that space and places and quickly deletes that block. Basically, holding right click ad the jump button to pillar doesn't work anymore- you have to time it perfectly for it to work. –Preceding unsigned comment was added by 68.61.184.212 (Talk) .

 * Newly-created oak slabs should behave the same as the other new slab types as they have a new block ID. 'Old' slabs (from before the introduction of the new slab types) should behave as they always used to. I believe the reason for this is that 'old' slabs' are also nonflammable, and changing them to flammable (another change that also came in when their tool type was changed) would have broken a lot of existing designs - for example, many people used the old fireproof wooden slabs around their fireplaces. --82.69.54.207 00:59, 18 July 2012 (UTC)

undefinedmp Not sure if anyone has noticed, but when you place Redstone Dust on sand, then pressing the left mouse button and right very shortly after (Holding down once pressed), as expected, the redstone will appear then disappear, but it seems to change the metadata of the sand block to the following (There may be more): TNT, Bricks, Grass, Stone, Iron Block, and some others incomprehensible to see. The metadata changes around every tick, and it turns back to sand every other tick and continues until you stop doing the above. This is a bug, since I am deadly sure that doing the actions shouldn't do that, and to back it up, I DID look in the code, and found nothing of doing the bug in question.

 * Falling sand and gravel are entities and cob webs slow down every entity so thats more of an annoyance --Bljat 14:29, 10 July 2012 (UTC)
 * That's the technical reason behind this bug but neither it's realistic in any way nor it makes sense for simple users who don't understand entities and it's probably not intended, too. Falling block entities should probably be unaffected by webs or they should destroy webs or maybe even become "solid" on top of them. -- JonHa97 07:27, 11 July 2012 (UTC)
 * The reason this exists the way it is not to do with technical reasons, but because falling sand/gravel entities convert themselves to items when they fall on certain objects like torches, pressure plates, and of course spider webs, to name a few. Fixing this bug would cause Mojang some major headaches having to code different reactions for different blocks just because of an unrealistic behaviour, and would break anti-suffocation measures most players use when they want to dig upwards to collect blocks like sand or gravel.  I also think that this is both an annoyance and intended behaviour as cobwebs and gravel have interacted in this way ever since they were introduced in mineshafts.  I vote to downgrade this to annoyance or have it removed. BrickVoid 10:40, 11 July 2012 (UTC)
 * Just because it was like this since the beginning doesn't mean it's intended. Might be just an oversight. And until a Mojang guy states that this is intended, I don't believe it, because it really looks stupid. On the other hand, falling sand on cobwebs is IMHO a rather unusual thing, so it's not really annoying. Might just leave this bug here until someone from Mojang fixes this or states that the current behavior is intended/not worth fixing. -- JonHa97 21:04, 11 July 2012 (UTC)
 * I believe that a Mojang developer already stated in a previous snapshot version that this behaviour is intended and not actually a bug. However, it has been so long since that statement was made that I cannot find the relevant snapshot listing where this statement was made so a citation from someone would be needed stating on what page this wiki has them saying this.

a A very annoying bug or something, when you try to place different kinds of slabs on top of eachother, they seem to not stack into a regular block, but have the missing half space. Fosofial 12:13, 18 July 2012 (EST)
 * Clearly not a bug or anything. The very basic rule of Minecraft mechanics dictate that one m³ space can only be occupied by one block at a time and not two different. By the same rule you cannot place e.g. a ladder and a torch in one space. --Kumasasa 06:41, 19 July 2012 (UTC)

a! Double Place: Often (very often several times in a row) when I attempt to place a block with a single right click, a second block instantaneously appears (often in the same frame). Second solid blocks are usually in the way, which can be disastrous when doing an emergency placement in battle. Non-solid second blocks (usually torches) often appear behind me. With this glitch, I always hear a second placement sound almost simultaneous with the first. I think this is a side effect of continuous placement mode (backpedaling or strafing to place many blocks with a single click), which I don't want to lose. My suggestion is to set block placement to "semi-automatic" (one click, one block) while holding shift. I also recommend this be done with breaking blocks in Creative, but should not be necessary in Survival. (Note: I do not believe the observed mid-air, behind-the-player dirt placement in this video (at 14:30) is related.) -- Featherwinglove 15:45, 10 July 2012 (UTC)
 * Slow computers exhibit a noticeable lag spike when placing or removing blocks. During this lag spike, input is not refreshed but the counter for continuous placement still goes on causing blocks to be placed. Most probably a bug, since the timing should wait at least one frame before confirming more block placements as this can cause a chain reaction. --Steve G. Wood 18:44, 11 July 2012 (UTC)

a If you place a slab on a grass block (that has tall grass on it) from above (standing next to, looking down at where you are to place the slab), the game erases the grass and sets the block on the top half of the box. Common sense would say that the slab should replace the grass but be placed on the bottom half of the box. I assume this happens because the game uses the grass' bounding box to determine if the slab should be placed in the upper or lower half of the box. --5thHorseman 19:58, 5 July 2012 (UTC)

a If you place a block to make a wall and stand as close as possible to that wall, and then place a block, the game renders the block for a moment, then disappears.

a Mushroom blocks can't be harvested or placed properly, reverting to damage/data value 0, a block which appears to use the mushroom pore texture on all six sides. This makes it impossible to use the red, brown, and white mushroom block textures in creations without using pistons to push blocks around. It is also inconsistent with the expected behavior of silk touch: if silk touch is capable of harvesting a block, it should not transform it upon harvesting. Transforming a block upon its placement (which happens when placing mushroom blocks of any damage value, obtained through cheats available in vanilla) is also completely illogical and a roadblock to making things from the mushroom blocks. Perhaps mushroom blocks could be made properly harvestable as "Red/Brown Mushroom Top", "Red/Brown Mushroom Edge", "Red/Brown Mushroom Corner", and "Red/Brown Mushroom Stem", where the edge and corner blocks would be placed in a directional manner similar to pumpkins (upside-down mushroom blocks would not be available, as this would require splitting the current two mushroom block data values into multiple). --WolfieMario 13:44, 12 July 2012 (UTC)

f Many times while underground (This is only where I have noticed it), many blocks may be represented by a stone block, and will revert to their true image and properties if hit, or something is placed upon them. For example, while walking across a stone floor, it is possible to hear the noises of walking across gravel, and if you strike the blocks at your feet, they will turn into gravel. Or placing a torch on a stone wall will suddenly turn the block it was placed upon into dirt or gravel. This causes problems as it can also occur with blocks such as ores. Meaning that one can mine a vein of coal ore, only to miss some that simply look like stone until struck. This raises concerns of the possibility of passing up diamond ores for the same reason (While I have not seen this occur, I have no reason to believe it could not). If say a dirt block were represented by a stone block (I have also never seen any block other than stone behave this way. I have never seen a dirt block turn to stone nor any block turn to any other, other than stone turning to other blocks), and one were to destroy this block, it would respond to tools the same way a stone block would (be broken quickly by a pick), but when destroyed, is instantly and briefly replaced by a dirt block, then the dirt block disappears leaving a dirt block entity. In addition, although the stone block shares most of its properties with normal stone blocks, walking on it will produce the sound of walking on the block it represents, the dirt sound in this case. If one were to begin destroying this stone block and then stop, however, the stone block is then replaced by a dirt block and then has all the properties of a dirt block. A detonating creeper will also reveal the true identities of the stone blocks around it. However, if say a gravel block were represented by a stone block, and a creeper detonates standing near it, it will use stone's value of blast resistance during the explosion, then turn to gravel afterwards, creating the appearance of gravel or dirt being unnaturally close to an explosion.
 * This has happened to me several times also, and certainly not just underground. Started a new game, was seeking coal and dug out a small hole in a wall only to find cobblestone. Left to get coal elsewhere, returned to this "man made" hole I dug to find several coal blocks where actually there. Also dug out some cobblestone to be presented with dirt dropped. Quitting and reloading reveals the real blocks too, one area was showing cobblestone and I knew it was dirt, quit, reloaded and voila, it was dirt.

Additional info; if you pour water over these entities, they will wash away, but still can't be picked up even from the new position.

Annoyances a! Smelting redstone/lapis lazuli ore only gives you one of the item per block. So, basically, to get the four-five redstone/lapis, if you have it in ore form (thanks to Silk Touch), you'd have to place it down and mine it with a normal pickaxe. irunor, 16:18, 18 July 2012 (UTC)

Annoyances

a Sometimes upon entering The End sometimes the obsidian platform (where you spawn after entering the portal to The End) is way outside The End island out into the void. Very annoying if you don't bring any blocks with you to place so you can reach The End island from the spawn point as well as the ender dragon easily pushing you off the obsidian into the void therefore killing you and having your time wasted making preparations before entering The End (happened in SP). --McLaren_231 10:32, 21 July 2012 (GMT)

a NPC villages should create a layer of dirt or something to cover up holes in the ground so villagers won't fall in, also villages should be able to make clearings or flat areas in biomes so they can spawn in forests, or mountains. I also don't see why villages never spawn in the icy plains.

Fixed/Skipped f To describe many of the bug reports related to world generation, when unpopulated chunks are populated, the new changes to the chunks aren't always correctly sent to the client. This means that if you walk a ways or mine long tunnels underground and go into newly generated chunks, ores veins and other features will be invisible until certain circumstances make them visible to the client. It shouldn't be a difficult fix to have the chunk population process inform the client of the changes. I believe this is a major bug because so many people are reporting problems related to it. LB 23:37, 8 July 2012 (UTC)
 * (Duplicate) Every once in a while there will be blocks that appear as one kind, but change texture to their normal block when right-clicked.

! When re-entering a "Singleplayer" world inside a village at night there may be some or even hordes of zombies all over the place, even if the village is completely lit. I've even seen 2 zombies appear inside a house with a 3x3 floor that has a torch on the floor (which then proceeded to try to break out of said house).

I even slept most nights so they didn't get too badly zombied. Actually a bit annoying. --82.69.54.207 15:48, 16 July 2012 (UTC)
 * Are you sure there's no pits nearby? I've found that naturally occurring villages tend to lose villagers to the terrain unless you take measures to pen them in. This could be considered the bug, really :) I've never lost a villager that I've secured in a hole, or locked in an inescapable room. Unless a zombie horde started, of course. --5thHorseman 22:12, 16 July 2012 (UTC)
 * Well, I don't think there were any holes nearby for them to blunder into, and I went over the area quite thoroughly. I fenced around the two bigger holes I did find and lit them up, and if any villagers had fallen down there I'd have met them while mining. Finally, I blocked the last two villagers in a building for several days and they still didn't take the hint. Also, this isn't so much about losing villagers, it's about the ones that remained not breeding even while there were still 5-6 of them left in a village with 12 buildings (and building with doors to boot!). I even removed and re-added most of the doors to see if that would help.--82.69.54.207 22:57, 16 July 2012 (UTC)
 * You need approximately 3 doors per villager (It's actually 0.35 villagers per door) so if you had 12 buildings, they would only mate to produce up to 4 villagers. Build a structure like the image above, or knock holes in all the non-doored walls and add doors, and you should hopefully start to see love in the air. --5thHorseman 23:39, 16 July 2012 (UTC)
 * Thanks. I've just been counting doors and the distances between them. But assuming the wiki info in NPC Village is accurate, the current setup looks likely to doom many villages to slow extinction unless the player intervenes. [Mojang devs: Is this intentional, and is the wiki correct?] Apparently villagers only count doors within 16 blocks' radius, which means a random villager must count at least six doors in range before they are willing to breed. That often doesn't happen on village outskirts where even 3-4 may be a high value, and 0.35&times;4 no breeding. I had a near-empty village, but it seems the corner the surviving villagers were in counted as 'fully populated' so they wouldn't breed. That suggests a weakness in the breeding algorithm to me. Might it be better to have an 'overcrowding threshhold' at which they stop breeding? 2.4 villagers per door, say, would give a much more medieval feel.--82.69.54.207 23:58, 16 July 2012 (UTC)

 * It is stated in the wiki article for wolves that the requirements for breeding are that they be tamed and at full health. Also, on feeding them, I don't think that this is an oversight, either, as it allows for role playing potential for animal lovers who would want to heal damaged wild wolves.  Vote to remove this as neither being able to feed them nor them not breeding if fed are oversights, and therefore definitely not bugs. BrickVoid 11:01, 16 July 2012 (UTC)

undefined Mobs/Animals can push each other through wall, then they seemingly appear where they actually aren't.

When they are on the upside-down slab, they're above the slab and therefore fully exposed to the sunlight.

A When killing any meat mob (cow, pig, chicken) in one hit with a Fire Aspect enchanted sword they do not drop their "cooked" meat, as they do if they were to burn to death due to the Fire Aspect.

How do I get a talk page link to here so I can discuss this on that page instead of here, for bug tracking purposes? BrickVoid 21:40, 6 July 2012 (UTC)
 * I've done some testing on this bug and with the help of the newly implemented /debug command available with cheats enabled, I found that whenever the client enters a jungle biome, the gamerenderer section is allowed to go to town and that part of the pie graph on the F3 screen jumps to 98% and beyond, when in fancy graphics mode. What this does is suck dry available CPU utilization for all other resources, including player movement, shown on the F3 debug graph.  I request that the rendering bugs I'm reporting be treated as major bugs, because if I cannot move around in Minecraft, I cannot play, if I cannot play, I do not see any further point in trying to test and identify bugs.

undefinedmp Right clicking a chest three times in rapid succession makes the chest appear to be stuck in the open position again. Needs a little bit of latency to reproduce. Using the chest once more makes it close as normal. --Steve G. Wood 12:38, 11 July 2012 (UTC)
 * Sometimes, the bugged chest will invert its open state i. e. it will close when you are using the chest. --Steve G. Wood 12:38, 11 July 2012 (UTC)
 * It's actually just if you right click a chest more than once before it opens. It has been a bug in SMP for a while now - I think chests keep track of how many people are 'in' them by adding to a value when you right click and subtracting when you exit. Thus if you right click twice before it opens, it only subtracts once when it closes. LB ( T 22:16, 11 July 2012 (UTC)

Annoyances

a! Interface redrawing is slowed signifcantly by in-game lag. What happens is that whenever I am in a jungle and experiencing lag, I hit Esc to enter into the UI to swap the graphics from Fancy to Fast, but doing this very thing means that the UI is lagged very badly until the Fast graphics are actually enabled in the UI. If Mojang could at least separate the draw/redraw of the UI from the draw/redraw of the world rendering I would be able to at least swap to a different rendering mode much more easily. Additionally, if Mojang could come up with an interim fix for jungle biomes that limits the amount of lag they are allowed to force into the rendering of the jungle biome until Mojang get to fixing it in 1.4 that would be very helpful to people lagging in jungle biomes.

Because of this, the sound effect that plays when using a portal does not play, either. There is no reason for it to say "Downloading Terrain" when it could just use the old screen.

undefined When playing offline, if you save and quit to title and then load the world again, all maps you have on you will have been erased. Basilo1146 00:32, 16 July 2012(UTC)
 * I wonder if this is related to the signs having no text. If it is, the maps probably have the data, they're just not showing it. --5thHorseman 12:43, 16 July 2012 (UTC)
 * I don't know about that, whenever I hold the map again it does the little loading thing again. --Basilo1146 22:05, 19 July (UTC)
 * You could test by exiting your world and then loading it in the release version (not a snapshot) to see if the maps come back. --5thHorseman 22:07, 19 July 2012 (UTC)

Annoyances 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 page you have to re-write the entire page. Book writing should have the moveable cursor, text selection and cut/paste similar to chat. Same applies to writing signs. Gravemind2401 09:36, 10 July 2012 (UTC)

a! It is impossible to type in alternate scripts in Minecraft. Because of this, in certain languages the search function is unusable except for music discs. TorchicBlaziken 01:36, 8 July 2012 (UTC)

a Now that the other wooden stair types has been added, the "Building Blocks" section needs to be reordered, also Oak Wood Stairs needs to go right before Spruce Wood Stairs. Image: http://h9.abload.de/img/2012-07-05_19.05.556px8y.png

aEmerald Blocks and Emerald Ore Blocks are coloured grey on Maps (Might also apply to other blocks that were added recently) [Note: This entry has been deleted before without a fix being confirmed. In case it is already fixed, feel free to delete] --Supersonic112 22:33, 5 July 2012 (UTC)
 * IT's a "stone" block so it appear grey - 90.192.72.150 17:50, 6 July 2012 (UTC)

aCreative mode inventory: "Redstone" has trap doors and fence gates, as well as normal doors. "Decoration blocks" has fences (including panes and iron bars), but does not have fence gates. I don't think of "Redstone" when I think of doors or fence gates; I think of fences and gates together.

Implication: A block can/should be on multiple places in the creative inventory screens.

a Pirate (and probably other language options that have thinner writing) is offset and often has an extra set of black lines that can make it very hard to tell stack sizes and read signs.

aMaps now take much longer to create the overhead of the area you are in when exploring.--Basilo1146 22:10 19 July (UTC)

! You cannot use polish letters: ąężźćśńł. Only "ó" is allowed. This bug is on all versions of Minecraft. I hope you will fix this, because it is very annoying in multiplayer chat. --velvetpro 12:32, 7 July 2012 (UTC)
