!!cr Minecraft crashes when you are in creative mode, have the chat button set to Button 1 (left mouse), enter text in the compass tab, change tabs, then exit inventory. 100% reproduceable for me.

undefined --MarcWatson

!!When I open Minecraft, everything is fine, but when I quit out of it, the "javaw.exe" process continues to run as seen in the Windows Task Manager. Every time I try to "End the Process" nothing happens, and even the "End Process Tree" does not do anything. The only way to get rid of the process completely is to restart my machine. It is possible for me to have multiple "javaw.exe" processes running due to this bug.

I've never had this problem until installing Minecraft 1.3.1, as 1.2.5 and the previous versions did not cause this to happen. I am using Windows 7 64-bit and Java 7 Update 5 (I have both the 32-bit and the 64-bit installed).

!! Going on certain servers causes the game to crash immediately after logging in. Here's the report

!! When I start up a LAN server, 2 - 5 minutes into the game it freezes then just closes unexpectedly on me without an error report! Happens so much to me I deleted everything to do with minecraft on my computer.

!! With a fresh Minecraft 1.3.1, the default texture pack, and a brand new JRE, Minecraft crashes when I try to enter a game in singleplayer (I don't know about multiplayer). It doesn't matter if I'm creating a new game or loading an old world. The game stops on "Building Terrain", then goes to the crash screen. Minecraft 1.2.5 worked fine for me.

 * I have a hunch it is because you are logged into your computer as a Guest. Try logging in as a normal user (you might need to reinstall Minecraft after doing so.) The JVM is complaining that it does not have write access for the Minecraft crash report. I'm guessing that Minecraft itself crashed because it didn't have write access to save your progress in the game. -- Featherwinglove 23:33, 8 August 2012 (UTC)

 * I can confirm this. My crash log is as follows: undefined --Bilde2910 17:29, 4 August 2012 (UTC)
 * Your error does not appear to confirm the one above as it is different - yours appears to be caused by your graphics driver - see the problematic frame - I suggest checking your drivers are up to date and are set to support OPEN GL 1.4 as a minimum. -Aurelius 21:26, 6 August 2012 (UTC)
 * I can confirm as well, it has closed on me nearly 20 times within 24 hours of game play each with its own report. The latest is as follows:

 * Well, maybe this is irrelebant. But I use a mod that restores SSP to 1.3.1, and the randomly crashed has gone. Really don't know what to think :s

--Ficion 06:57, 5 August 2012 (UTC)
 * This error report also does not appear to confirm the ones above as it is different again - yours appears to be caused by an audio library - see the problematic frame and the "lwjgl" - I am not as familiar with those errors but I suggest checking the Java installation, reinstalling the latest Java, checking the Lightweight Java Game Library (lwjgl) and performing a clean install of the latest minecraft. -Aurelius 21:26, 6 August 2012 (UTC)

It usually restarts just fine when I open the program back up, but sometimes it freezes and I have to force quit. The last time it actually crashed and gave me a crash report and it is as follows: undefined --Thrashr24 22:39, 4 August 2012 (UTC)


 * This bug has persisted as far back as I've had the paid Minecraft on this computer (dating back to Beta 1.3). I have a laptop and it does NOT occur there, only on my desktop computer. It's really annoying. These error messages are only given in the downloadable client, playing in browser it does happen too, but Minecraft freezes the computer and to quit it, I have to do Ctrl+Shift+Esc and then Ctrl+Alt+Del twice to even get up something else than the frozen Java screen (fullscreen in browser, haven't tested standard size). Then I have to terminate the java process two or three times to get it to close. --Bilde2910 08:10, 5 August 2012 (UTC)

 * It seems like that Minecraft can't detect your graphics card. Are you playing in a browser or with the launcher? If you are playing within a browser, please try to start Minecraft with the launcher. If that doesn't help, try to force update yor Minecraft. And if that doesn't help, try to update your graphics driver. --130.83.20.209 04:56, 4 August 2012 (UTC)

! Minecraft used to work on WinXP 32bit with ~3,4 GB usable RAM until beta 1.7.3 even with "Far" video settings. I just got the famous missing chunks, which did NOT appear with "Normal" settings. After beta 1.8 with "Far", the jawaw.exe (the JavaVM) running Minecraft eats up memory over time (several minutes, faster when flying around) until hitting approximately 1 GB RAM, then Minecraft begins to lag heavily with freeze times from few seconds up to minutes, but without any major CPU usage. The spawn on an anarchic server even forced me to set video to "Short", because of freezing. F3 doesn't show any evidence of such a memory consumption. Allocating more memory is no use, because starting Minecraft fails if set over 1300MB and this does nothing to the freezing, which then starts even earlier, at 900MB RAM consumption. When set to "Normal", the JavaVM with Minecraft uses between 600-1000 MB. While there is a warning for the "Far" setting, there has to be a bug, because this is an unidentified RAM usage. If this bug is not in the game system, at least the debug screen has to be corrected. (CAPTCHA system seems broken for me and doesn't let me post links) Screenshot: h__p://i.imgur.com/lFgpq.png --78.35.138.237 03:29, 2 August 2012 (UTC)
 * The 32-bit Java VM cannot give Minecraft enough memory over time in "Far" mode, and you've perfectly described the result: The game runs out of memory, gets laggy, and ultimately freezes or crashes. Don't use Far mode on 32-bit systems like the warning says--problem solved.  Running out of memory isn't a bug unless there's a memory leak, which isn't indicated.  The Java VM and the libraries Minecraft use require memory above and beyond what Minecraft is using internally.  ---Jovet 09:38, 2 August 2012 (UTC)
 * After the third such crash (before finally seeing that I had Far on), and running with Shift-F3, I managed to catch some numbers: Used memory was 406MB/512MB and Allocated memory was 512MB/989MB on the frame that the game crashed. Still, this is nothing compared to the problems I had with Optifine 1.2.5!! -- Featherwinglove 05:09, 5 August 2012 (UTC)

! In 1.3.1 i have enabled the chest on start as well as cheat codes and in starting without creative mode when i enable creative and return to default game mode i am unable to break any blocks. restarting minecraft does not fix it. switching back to creative and then to default does not fix it either.

 * Dual core - - no BS, be polite Darkinnit 09:40, 2 August 2012 (UTC)
 * A unmodded Minecraft before 1.3 is single threaded. One thread handles everything: block update, entity update, chunk (un-)loading as well as rendering. With the 1.3 update, Minecraft is now dual threaded. One thread simulates the game: that's the internal server. And another thread renders the game: that's the client. This is roughly how Mojang merged the SSP and SMP. For details see Dinnerbone's forum post: www.minecraftforum.net/topic/1342074-how-do-we-feel-about-13/page__st__40#entry16392586  So, after all, it is normal that your CPU usage is above 140%. If your Mac is overheating, it's most probably not Minecaft's fault. --130.83.20.209 04:45, 4 August 2012 (UTC)


 * Thanks for that explanation, I was aware of the change but did not expect it to take affect so dramatically. I'm still of the opinion that it was not intended for CPU usage to be this high. I run plenty of multithreaded high demand programs on my mac using muc less CPU, a constant precentage in this range is nuts really. Another point I want to take up is that when using the optifine mod with previous releases, enabling the 'Smooth FPS' option in settings greatly reduced my CPU usage when playing the game. If any devs read that perhaps that can help.

Attempting to launch 1.3 with magic launcher worked just fine (just replaced the old jar file in the config). Attempting to launch 1.3.1 gave errors (see graphical below).

! mp ! It seems that players who use fly hacks can cause an unmodded server to crash severely. This means that a public vanilla Minecraft server is impossible because it is not possible to ban cheaters fast enough to prevent this condition. Even a moderate flight by cheater clients can completely cripple a server in seconds. --Inertia

undefined Running on Mountain Lion on a Macbook Pro 2010, after a few minutes of play (wither single or multiplayer, network or local), the FPS will start to lag severely, from 40 or so in normal play dropping down to 2 or so for a few seconds. This seems to be particularly bad when turning. Keys that are pressed at the time will also 'stick', leaving you moving uncontrollably at a very slow frame rate. The rate will recover again after a couple of seconds, but once this has started it keeps happening and the game generally slows down over time until it becomes basically unplayable. CPU usage doesn't change (and remains fairly low), and nothing odd seems to appear in the F3 view. If you disconnect (or quit if in SP) and reconnect (or reload), the problem goes away. However, just as if you had connected for the first time, it starts happening again after a few minutes.

Annoyances

undefined Sometimes when moving from minecraft to another window, the game manages to unpause itself, resulting in the mouse being limited to moving in the region the minecraft window takes, even if it is behind other windows. Easiest way out of the problem as far as I can tell was to simply Alt-Tab into minecraft and manually pause it. Also, this did not happen every time I move to a different window, but it has happened at least twice.

a mp When using an automated piston system to push arrows off of the face of an arrow detector, there is fairly high chance of causing a glitch that causes all pressure plates within an area measuring 21x21x21 blocks to stay active once they've been activated. This glitch remains in effect until the area has been unloaded from memory. Video: http://www.youtube.com/watch?v=tsyz5Kh5Qfo

a sp Win7. Due to single player running a server. you can now lag out of your own server in SSP. You will not be able to place or break blocks. quiting and re-joining can fix this. Windows 7 Home Premium 64 bit -- 02:09, 8 August 2012 (UTC)

a If minecraft is run from the comand line, it will spit out asdf as soon as it starts. It works normaly otherwise.

a sp Minecraft seems to continue rendering the world while in the pause menu when pressing Esc during Singleplayer. That doesn't seem necessary since the time seems stopped and the background is completely static. The background should be either black (at least as an option) or be replaced by a screenshot while in the menu with the game rendering/logic loop completely paused. This should be a nice way to move to other programs running in the background (such as a browser to look up things on the wiki) on slower systems without Minecraft eating up so much CPU. Not sure if this is already the case but it seems weird that Minecraft still uses so much of the CPU while completely paused.

Gameplay
Bugs [!] = ! Upon respawning in after death. Player will fall through and out of the world resulting in death once more. This is not a cycle but falling out of the world occurs once after a death and respawn. 75.157.35.253--- WizardAntechu

! Saved chunks can get replaced by random, other chunks. While playing SSP, i realized that landscape in front of my house was not as it was before, so i took a look at it and it turns out that 3 of 8x8 chunks got replaced. Not sure what cuased it, but it occured after I went to the nether. This bug is major bug, because it can do severe damage to built structures.--Cronation 16:15, 13 August 2012 (UTC)

! mp If you die exactly as you disconnect from a server, the death message is sent to other players (after the leaving message) and any carried items are dropped - though this is not saved to your profile, resulting in the items being duplicated. --UnbornX69 15:09, 9 August 2012 (UTC)

! ssp csm You can glitch through blocks, and fall into the void when exiting a nether portal. Screen keeps on shaking and you can only walk on the block that you are on now(shakes even more when sneaking), you can not jump. When you get unstuck, you fall down a block(and into the void), only way to get out without dying is to edit yourself out. Minecraft5025 17:41, 7 August 2012 (UTC)
 * This happens on normal maps, too. --71.168.192.48 03:06, 13 August 2012 (UTC)

! The spawn location for players when they start a new map or die on a map is randomized, and as a result on certain maps... especially "survival island" maps, are rendered useless due to this change in behavior from 1.2.5. The problem is especially rampant on something like a SkyBlock type map (or a variant) where if the whole area near the spawn location out to +/- 10 meters is not safe to spawn in (it usually isn't on these kind of maps) that there is a strong possibility of simply rendering the map unplayable as you keep respawning over and over again in the dangerous areas. I've tracked where this "fuzz" is being added to a specific section of code in the "EntityPlayerMP" class constructor (via MCP):

The problem with this particular section of code is that it presumes wrongly that every location near the spawn is safe to spawn into. This does render a certain class of user-created maps as either useless or sort of turns them into a kind of "hardcore" mode as those maps are unrecoverable upon death. Even changing the spawn point doesn't help as this function explicitly moves that location about a bit in a random fashion. I understand the problem it was trying to solve, as on multi-player servers with hundreds of players it sometimes can get annoying to have everybody spawn at precisely the same point on a server. For single player situations (or for small groups of players) that isn't nearly so big of a deal. This is a cheap fix to a serious problem that IMHO needs a better solution as it has unintended consequences. --Robert Horning 12:49, 4 August 2012 (UTC)


 * Hold on a second. Is this accurate:


 * Is this really setting Y based on X and Z, and then altering Z? If Y is based on the terrain at X/Z, then Y needs to be set LAST, not in the middle.

--Keybounce 20:04, 4 August 2012 (UTC)
 * p.s. Please have a code review. If that got through, who knows what else needs a check.


 * Yup, this is right out of the source code currently running MC 1.3.1. I see the other bug you are alluding to here.  I guess we are the code review team on this one.  BTW, as a "fix" here, I would suggest that the following ought to be the code change instead:


 * The point of the "spawn fuzz" would be to have something settable in the server parameters so server operators can define the spawn radius for their players, making it at large or as small as they need. By default this could remain 10 meters from the formal origin point when using the vanilla server, and for the "single player" users could be simply set to 0.  It is always nice to have custom settings that are user defined, isn't it?  --Robert Horning 20:28, 4 August 2012 (UTC)


 * Added note: While this particular bug is manifested mostly on custom maps, this is a general bug that really does need to be fixed for almost everybody, because of the effects of setting the y-coordinate after adjusting the z coordinate.  If the spawn area along the z-axis of a server (or even single player) is sloped, you don't start playing after respawn on the ground but instead either inside of the ground or above.  Furthermore, if your spawn area (server or single player) has "dangerous areas" that you can spawn in for any reason (a lava lake within +/- 10 meters in the x or z directions) there is a possibility you may end up in that location instead.  No subsequent check is being made to identify those "dangerous" locations.  While rare, it can be a problem even for ordinary maps generated by the game.  --Robert Horning 16:15, 8 August 2012 (UTC)

! When pillaring with sand/gravel, as you break blocks below, the player will occasionally be moved to one side and fall from the pillar. This occurs even if one block is broken at a time, with a pause between breaking blocks. Avatar6969 3 August 2012
 * I might have had this happen in 1.3, at the time I thought it was a bad key press, but I was confused because I had left Shift down at the time, fell off the pillar to my death. (I was processing gravel into flint) After this, I Void-fell twice before respawning properly, my bed only two, maybe three chunks away, and reported that as being possibly related to Nether portal void-falling. -- Featherwinglove 05:47, 5 August 2012 (UTC)
 * As a note, this happens a little bit when pillaring out in the open, but it REALLY does it when you are pillaring next to a wall. This is when I have noticed being moved to the side, and off of the pillar.  Perhaps this has something to do with the new boat/minecart mechanic where it moves you to the side instead of dropping you on top. Avatar6969 6 August 2012

undefined Boats are not properly synchronized between client and server. This is most noticeable when leaving a boat (you appear at the location the server thinks the boat is, not the client), but can happen when you re-enter a boat too (you try to enter it at the client position, appear to succeed, and start drowning a little while later because the server thinks you're in water and stopped swimming).

To replicate this bug, enter a boat, travel a few hundred metres (bonus points if you change direction once or twice to make an L or S or C curve). Then leave the boat (you'll be a dozen or so metres away). Then re-enter the boat at the location the client sees it, start your trip, and wait for drowning damage to occur.

Relogging re-synchronizes things, so as soon as you start drowning, relog, and you'll notice that you're at the bottom of the lake/ocean. Likewise, you can relog after leaving a boat to have it moved to its correct location. It's wise to relog before _entering_ any boat, just to make sure you avoid a drowning scenario if they drifted out of synch.

This definitely occurs in multiplayer. I haven't tested it on singleplayer; if it's sensitive to latency, it'll still occur but might be much less severe. --99.231.102.238 21:50, 14 August 2012 (UTC)

! sp When playing in singleplayer, I am in creative with cheats on, and I did a lot of building, then since my Windows computer crashes a lot, I saved and quit to title. When I rejoined my world, nothing was saved. I angrily tried building again, thinking it was just a one time thing, later I found out, it was not saving anything I did. I don't know if this is because of the new trial version you have, but I have a full account. I do not run any mods. I am not sure which category this is in, but I know that it is a major bug. I don't know if other people are getting it, but it happens to me every time that I play.
 * This also happens to me, although I play in singleplayer survival.
 * I seem to be having the same problem in singleplayer survival, just like the person above me. My inventory was the same as it was when I saved, meaning every block I had placed after the update (technically everything seeing as how this was a new map) was lost forever, including the contents of two chests. I did not use cheats, but I did turn on the bonus chest if that helps any.
 * Merged Duplicate sp When playing in single player, I am in survival with cheats off, and the game world consistently refuses to save. The first time, I dug underground to wait out the night, saved & quit in the middle of the night, and when I logged back in, the blocks were back, and I suffocated. The second time, I had just finished smelting some gold ore and put it in my inventory before I logged out, and when I came back, I had the ingots in my inventory but the gold ore was being smelted in the furnace. Third time, I'd returned to my base and put a full stack of iron and a quarter stack of gold in a chest. The next time I logged in, the iron and gold were both missing.
 * This happens to me as well, I really would like to see it fixed. Playing the game is pointless if you cannot save!
 * That's not "refusing to save", it's a buggy save. On the other hand, I've also had items go missing between chests, without saving in between.  Nothing more important than a stack of wood, but it's worrying. --Mental Mouse 02:12, 4 August 2012 (UTC)
 * One of the updates is this ~Decreased world saving intervals~ This is what I imagine causes one to spawn under lava when logging in underground (when last previous location on logging out was a 1+ block(s) above lava) and causes the saving bugs above.
 * I've also seen this in SMP, I had ~8 chests smelting half stacks of iron/gold etc. I went to the nether, and when I returned (chunk unload, then reload) the contents of the furnaces was partially missing. Some had a "stuck" fire icon about 1/2 done and were missing ore, some were still smelting with the right number of ingots and ore, and some were just ore.
 * This is confirmed by me, I had a rollback in which I lost many iron picks, blocks and a couple of diamond swords. Also a diamond pick was dis-enchanted by this.  I am playing in vanilla and I work very hard to get diamonds, I really would like to place diamond in chests without fear of deletion.  Mojang, please fix this!

! sp (Apologies to substitute541 for merging his original report as a bullet). I have tested rather extensively the death chunk loading bug. Apparently, the method of death is irrelevant, as this test started with a lava death, while I have previous experience with it via falling deaths and even Void-walking deaths resulting from this bug (I have not tested "/kill featherwinglove" in the 1.3 branch.) This one appears to be a merge phenomena where the server had the chunk loaded and operating properly, while the client did not, resulting in X-ray vision, out-of-bounds placing, and even a Cheshire sheep! The video is currently being uploaded, and I will post a link as soon as I have it available. -- Featherwinglove 15:24, 5 August 2012 (UTC)
 * Sometimes, when using the /kill command in 1.3.1, you spawn in a place where there are at-least 3 chunks which are not loaded (chunk error/world hole). Note, this is on SINGLEPLAYER, and the chunks will never load. I haven't tested this bug several times, but it could lead to a crash. I do have a screen capture though, and I'll post it on my deviantART(substitute541)
 * I believe this _may_ be related to the Nether portal chunk loading bug reported very extensively below (as most players probably travel through Nether portals more often than they die. ... Not saying I'm a n00b or anything, lol.) -- Featherwinglove 15:24, 5 August 2012 (UTC)

!Far away chunks don't update, and chunks aren't always loaded properly. You can see this glitch by using tnt. In a superflat world, create a long path of TNT. Ignite the tnt at the end of the path. wait in the same spot until all of the tnt has exploded. follor the craters from the tnt, and you will notice that it looks like some of the tnt hasn't exploded, even though it did. if you exit the world then enter it again, the world will properly update, and you will see the craters where the tnt that didn't look like it exploded was.

! lmp If the host for a LAN world changes (e. g., they were siblings), the new host will get the original host's items, and if the player who connects to the server is the host, they will get the items, exp, armor, etc. that the host has at the state it was published. I believe that if another player then joins the server, then they will get the same items and worn stuff as who last hosted the world. If the original host were to host again, they would have the last host's stuff. It is like they they have never player before, for they haven't, as a connected player. If a third player were to connect both times, it may keep his/her items, but I have not tested it. This issue reoccurs every time the host changes. I believe that this bug has something to do with a feature retaining to the items a player has on hand when leaving a world, and that ANY player can log into that world and have the items present at hand. And since the world must be opened to LAN, it is initially logged in as singleplayer, and so that event takes place. If a player who had connected to the world then hosted the world, their data would be lost. A protection or two must be placed, possibly toggleable, in order to resolve this. If offline, they must not be able to play on a LAN network, but should still have a separate profile than the rest. --Wormy14 13:02, 2 August 2012 (UTC) It has been deliberetly made this way, so other player getting your level gets your level as is.

 * For now, you can use a work-around by disconnecting and reconnecting BEFORE going through any portal. If it still happens, quickly dis/reconnect again and you should be on solid ground. 02:49 2 August 2012 (UTC)
 * Happens for me every single time I teleport back to the Overworld with my old world. After it happened in this direction I won't be able to teleport to the Nether either. Will do more testing with different/old/manipulated world files. -- Zuckel 08:25, 2 August 2012 (CET)
 * Happens for us with a portal sitting on 0,0 - every time going to the nether and most times coming from the nether. Another portal nearby has similar issues, but other portals in the world seem fine. Breaking and recreating the 0,0 portal does not resolve the issue. Could it be a divide by 0 error somewhere? 0,0 is not our spawn location if that makes any difference. Darkinnit 09:47, 2 August 2012 (UTC)
 * If this happens to you, you can also try to quickly switch to Creative mode and fly up and out of the danger zone of the void before you die. Then quit the world and re-enter, and it should then load okay.  You can then revert Creative mode.

 * I've tried around now and I can confirm Zair99's finds. My testing also showed that it doesn't happen when another player watches me come out of the portal, i.e. the chunk I port to is already loaded. Further, the "first time works" counter seems to be player specific. Trying with 2 players simultaneously, one could go through without problems and the other not, depending on which one had already ported before. Even further, the problem won't occur in case the world you port to is just now generated by that port. Experiencing the issue on any portal in my old world that I started with MC 1.0. Less often on fresh worlds. -- Zuckel 3.8.2012 20:47 CET
 * Was playing 2-players on a server, our first constructed Nether Portal is very glitchy for both of us, about half the time porting into rock or void similar to reports above. Something important - a ghast extinguished Nether side of portal, original side was fine, the other player walked in from overworld side and ended up maybe a portal height above the existing extinguished Nether side of the portal - and a NEW portal spawned up there where he came through, so now Nether has two portals stacked vertically atop each other. -- 21:28 (UTC+8) 5.8.2012

 * I experienced this on a multiplayer server after using a portal many times. It took a while before it happened to me, but when it did, I appeared in a chunk error where the portal should be (there was only one errored chunk). Rather than simply bobbing up and down, as you normally do in a chunk error, I began to fall, still occasionally bobbing. Passing below ground, as expected, I took suffocation damage. When I logged back in, I was back at the portal, but I retained the damage from suffocation. Perhaps making chunk errors have their original behavior (not letting the player fall through) would at least lessen the damage caused by this bug? --WolfieMario 20:01, 7 August 2012 (UTC)

 * I can confirm this error as it happened to me multiple times,only upon entry from the Overworld to the Nether, and i lost everything. I tried the Disconnect/Reconnect thing but had no luck and lost everything.  So i tested it further, i noticed if i went into a portal and turned any direction for any reason while it was doing the swirly votex, it caused the chunks to not load and me to eventually die, no matter how much i disconnected and reconnected.  Tried this many times and yes i agree this is a game breaker.  Hours spent mining a brand new diamond armor set and having it fully enchanted, amongst other valuable things, lost for good.  --Pyratic 23:00, 13 August 2012 (UTC)

 * I am also experiencing this. It doesn't matter what block it is at your side, if the water is pushing you into a corner you'll take damage regardless.

undefined Also, even on normal mode, zombies can in fact break down village doors (observed). On consideration, I'm pretty sure this is why I've had two villages depopulated on me, in 1.2.5 and 1.3 (villager spawning presumably isn't fast enough to replace the losses). (An alternative explanation would be buggy pathfinding... that is, accumulating damage from excessive drops.) No sign of iron golems, perhaps the villages aren't big enough. --Mental Mouse 03:41, 3 August 2012 (UTC)

 * That's "normal difficulty", survival mode. One thought is that the doors may be wrong-way-round:  The originally generated doors appear inset into their wall (that is, the inner side of their block).  When I place a new door from outside, it appears flush with the wall. --Mental Mouse 12:03, 3 August 2012 (UTC)

undefined On the Mac, it is possible to map sneak to caps lock. However, as soon as any menu comes up, any chest opened, etc, the sneak turns off, while caps lock stays on. On return to the game, caps lock is still on, but sneak is off.

In other words, when the key for sneak is pressed, sneak activates; when a menu/inventory/chest opens, sneak deactivates regardless of key state, and won't be reactivated until a new key_down event occurs, which in turn requires a key_up. The game gets out of sync with the physical state of the keyboard. --Keybounce 05:07, 3 August 2012 (UTC)

I also experience this on windows 7, but always assumed it was intended. the caps lock button acts like any other, and the caps lock light does not change sneak in any form(nor should it). menu's cancelling sneak on the other hand is a separate issue, and one I think shouldn't be fixed, it introduces risk for players sneaking around someones base, and prevents them from crafting and sneaking at the same time which is good from a gameplay point of view. --101.166.17.204 06:12, 3 August 2012 (UTC)

undefined Fishing: Compared to 1.2.5 single player:
 * It is harder to fish, in general:
 * Situations where I could fish in one deep water in 1.2.5 now fail; the bobber consistently gets stuck on the bottom.
 * The bobber seems to want to go farther out now
 * Fishing in a small area (3 land spaces, then 4 water spaces, with the water 1 deep) was easy in 1.2.5 single player, reasonable in 1.2.5 multiplayer, and painful/not doable now.
 * Fishing in 1 deep, 2x2 pond, by standing directly over the water and dropping the bobber down would result in the bobber floating in 1.2.5, and ground-stuck in 1.3.1 (Yes, I have that 1.2.5 on video -- link in a few days)
 * 1.3.1 multiplayer is giving me lots of false sounds and bobber movement, compared to 1.2.5 single player. In fairness, 1.2.5 multiplayer took me a while to learn how to fish, so it may be a similar issue of retraining.

1. Build this setup vertically, without the piston. B=Block R=Repeater D=Redstone dust -=Air

2. Place a lever where the L is, touching the block

3. Power the setup.

4. Place the piston on the P so that is facing the lever. If you are facing the lever, you should face the piston head. What happens: The piston will extend, but another arm extends downwards, destroying the repeater. If you destroy EITHER arm, the piston will drop.

! Client/server inconsistencies. I have had a couple of experiences with phantom damage, which I attribute to the client and server (SMP) disagreeing on my location. First, I was swimming across a small area of water towards a boat. When I reached it, I was in 1-deep water, but I couldn't interact with the boat. Suddenly, I started taking damage. I re-logged and found myself at the bottom of the lake, drowning, several blocks short of where the boat was. The second experience: I threw an enderpearl towards the top of a desert temple, and it hit the roof. I dropped down but immediately started taking damage. Again I could not interact with the world. Upon relogging, I reappeared briefly suffocating inside a block at roof level, and then dropped down a second time. Itsmartin 20:09, 3 August 2012 (UTC)

Annoyances

a! When opening or closing a door, if you end up inside the collision box of the new position, you can walk out and move around per normal, but you will be unable to interact with things like chests (clicking does nothing). You can relog to fix this; that leaves you next to the door (where the server presumably thinks you stayed). Happens in SP and MP, for myself and for friends. There isn't any time limit that I've noticed, though I haven't tested anything longer than tens of seconds. This is easy to do by accident if you aren't careful opening doors, or if you use automated door-close plates. There are a few related effects that I suspect are similar but don't have replication conditions for yet (involving the server and client disagreeing about where the player is, after things like teleporting into a railcart by clicking on it, or spawning from a Nether portal). The door glitch seems to be a case like this that's explicity triggerable (by collision box shennanigans). --99.231.102.238 06:47, 13 August 2012 (UTC)

a! Villager trading is still very much imbalanced. Non-farmables are undervalued, e.g. 4-5 diamond must be sold for a single emerald. Meanwhile, farmable items are overvalued, e.g. 19-29 paper for an emerald. With a sufficiently large sugarcane farm, I have been able to earn around 7.44 stacks of emerald in an hour, and while this is not in and of itself bad, these emeralds can be spent of many diamond items. The net result is a far bigger earning from farming than the most efficient mining practices, even with Fortune III. In fact, just one harvesting of the farm nets a player several doublechests of diamond items, which is very overpowered. In addition, many prices are nonsensical, e.g. iron and gold are considered equal in value, and mundane items such as compasses are considered more valuable than diamond tools. Server administrators are considering disabling trading and villagers on their servers because of the current imbalance, so this is a major annoyance. --WolfieMario 21:27, 30 July 2012 (UTC)

 * As a note to Mojang employees (Sorry, I'm just worried this'll get glossed over): the discussion contains various suggestions to help fix this issue.

a! If you are in a minecart next to a glass pane wall, exiting the cart can leave you on the other side of the wall. This can be fatal in, for example, overhead tunnels in the nether. This happens when facing any direction, only when the cart is up against a wall on 2 of the 4 sides. An example of this can be found at http://img.127001.org/img/2012-08-10_15.16.05.png - this does not happen with glass blocks, only with thin glass panes, iron bars, or wooden fences.--Frymaster 14:58, 10 August 2012 (UTC)

a Falling in to the void kills you. Why? The player (in Survival) should never be able to reach there by normal means, so most, if not all times they end up in the void is due to a bug. Players should never be intentionally killed by bugs. Falling in to the void should simply teleport the player to their spawn, with their inventory intact. Moleculor 01:06, 2 August 2012 (UTC)

a Lava several blocks below ground level sets things afire on the surface. Seen this in several places. --Mental Mouse 02:12, 4 August 2012 (UTC)
 * Lava and fire can ignite in a 3x8x3 area starting 1 below them. while this makes sense since things start to burn because they reach a certain temperature rather than having flames next to them (flame are of course a heat source but if they weren't they wouldn't ignite anything). the only "flaw" in the minecraft system is that non flamable blocks can't act as "heatshield" but then even the best uncooled heatshield will let the heat through once it has been heated enough. Since realistic temperature probably won't make it into the game the solutions would be either leave it as it is and adapt the building style (blocks won't start to burn if there isn't an air block next to them in the "ignition area") or make blocks with a full hitbox from below block the ignition area for the above part of that air column it is in (which probably will cause more server load) 9.33.122.76 15:18, 4 August 2012 (UTC)
 * Eight high through dirt and stone? that's insane, and not what I was experiencing in 1.2.5, or even most places in this world (a few squares away, I've been mining obsidian with no problems, even when I uncovered remaining lava).  I think this may be the same bug as Nabetsu122's "random fires".  I hadn't considered the idea that they might simply be random, and the lava's presence coincidental.  Incidentally, even after putting the fire out, I did get the "I'm on fire" animation briefly when walking over the spot, but I didn't stay on fire.  --Mental Mouse 14:19, 5 August 2012 (UTC)

a sp Random fires sprout from nowhere in one particular chunk, but does not seem to deal any damage. After checking the surrounding area (This is in the swamplands), I have not found any source of ignition, such as lava or other fires. Destroying the block it is on makes it invisible, and walking through it still causes the fire animation until the block it is occupying is replaced or logging out/in. Although it is a HD texture in this video, a fresh minecraft.jar still causes this problem. http://www.youtube.com/watch?v=RxLzDXEMnwY --Nabetsu122 05:26, 5 August 2012 (UTC)
 * I noticed the same bug, but its prevalence increased during thunderstorms. Although lightning does not strike the particular blocks (trees, mostly) they catch on fire.  The fire does not go out in the rain or from punching, but dumping a bucket of water or replacing the block the fire texture is occupying (not the block the fire is attached to) causes it to disappear.  Stepping in the fire causes no damage, but still causes the 'on fire' animation. --Salisian

Bugs

! In the Overworld, if blocks, fence, etc. are broken over soul sand, the broken blocks glitch out, and become "stuck." Removing the soul sand, and filling the area from floor to ceiling seems to cause the items to "snap back." Avatar6969 7 August, 2012

! Major bug with pistons that breaks many designs. In certain configurations, the pistons will "stick" into a form where they are both extended and retracted at the same time. The only way to reset them is to break the piston and replace it. This is easily reproduced in a design such as this: i50.tinypic.com/mm4i7q.png. As you can see, the top row of pistons are both extended and retracted at the same time. If you build this design and power the pistons while the reeds are grown, they will stick every time. Still experimenting but it has something to do with pistons pushing two blocks/items across from each other, or something related.
 * The same bug has seemed to exist since at least beta 1.7.3 on our multiplayer server. In a smiliar setup to the one in the link above, small clusters of pistons have failed to update and retract (but not entire rows). --Huddersfudlien 13:58, 8 August 2012 (UTC)

undefined Redstone timing errors in 131, 27a and 125 multiplayer that works just fine in 125 single player.
 * Do you mean Minecraft 1.2.5, 12w27a, and 1.3.1?

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, and 131 release, it will lose its timing. Approximately 15 16 tests; 14 go to lockup (the button side of the rs-nor being on all the time), and one two to inaccurate stable timing (on pulse is less than 9 redstone ticks; off pulse is longer than 5.)

Then I grab another diamond pick from my inventory and, lo, my old 'broken' pickaxe is back! It happens precisely when I take my other pickaxe from the inventory and place it in my first quick slot, and when it's placed there, there is the old almost broken pickaxe stuck at my mouse cursor (so I can drop it in my inventory).

undefined The map item becomes increasingly unusable as more exist in a world. There are no issues for a map with a low number, such as map_0. However, around map_50 issues start occurring, and these issues seem guaranteed at around map_100. Maps higher than 150 tend to be entirely useless. The issue in question? The client fails to display the correct map, instead displaying an arbitrary number and blank map. This number will increment when the player drops and picks it back up, or attempts to use a crafting table or other form of GUI except the inventory. Once the map has hit the correct number, it may be used, but the client fails to properly display any regions which have already been mapped. At low map numbers, this manifests as vertical streaks across mapped areas. At around 150 or so, these areas are simply blank, and will only display content which has appeared since the last time the map was viewed. When new areas are mapped, or existing areas are updated, only the changed pixels will display to the client; all else will remain blank. On large servers, this makes the map item essentially unusable: once a map is 100% complete, it will only display as a blank map to players. This issue has been present on servers for a long time, although I personally have usually only experienced maps where half of the vertical columns of pixels failed to load; as a server I play on has 150+ maps now, they have become utterly unusable blank rectangles. The issue is now present in singleplayer as well. --WolfieMario 01:47, 4 August 2012 (UTC)

! sp I have a house built into the side of a mountain. I was working in the Nether one time and when I needed some resources from my house, I went through my Nether Portal and came out with the portal surrounded in stone. I had to mine myself out of there to realise that part of my house had just reset. The chunk had replaced everything with what it used to be. Screenshot1 Screenshot2 It has destroyed half of my storage room and I can't get any of this stuff back.

! sp Large Biome worlds have a very high chance of generating incorrect chunks, mainly ocean in landmasses such as grassland. This leads the surrounding land to generate beaches or be a sheer wall around the incorrect chunk.

undefined There might be some problem with the generation of structures. In the seed 6143255795800914827 at X: 174 Y: 74 Z: 534 it is possible to see that a Desert Pyramid spawned in a Jungle/River biome, as seen in the F3 menu.
 * I've also seen a Jungle Temple that was generated almost completely over air, though the entrance was reachable via high ground, brush, and vines. --Mental Mouse 12:07, 3 August 2012 (UTC)
 * The problem is that the same piece of code is responsible for generating both desert and jungle temples. Temples are allowed to generate in desert, desert hills, and jungle biomes. If the block in the center of the chunk where it starts generating is part of a jungle biome, it will be a jungle temple; otherwise it will be a desert temple. However, this single block is often in a jungle hills, river, or other neighboring biome, resulting in desert temples appearing in jungles. A solution would be to sample several other blocks (e.g., corners of the chunk) until either desert (hills) or jungle (hills) is found. -- Orthotope 06:18, 15 August 2012 (UTC)

undefined sp A pair of bugs that have been around for quite a while, but still exist in 1.3.1: First, 'Save and quit to title' does not close all the loaded region files properly. If a world is deleted after playing it, some of the region files may not be removed as they are considered 'in-use' by the operating system. This wouldn't be too bad, were it not compounded by the second bug: if a new world is created with the same name, Minecraft will happily re-use the leftover chunks. This happens reliably on Windows, haven't tested other OSs. Easiest solution would be to check for and delete any existing files when creating a new world. -- Orthotope 06:18, 15 August 2012 (UTC)

Mobs/NPCs/Animals
Bugs

! Mob programming in general seem somewhat broken :
 * Mob movements are laggy and unpredictable mmaking them hard to hit or avoid (particulary noticable with Attaking Spiders)
 * Mobs sometimes stop moving and just turn on the block they are standing
 * Villagers other than farmers tend to despawn
 * It's impossible to hit a Creeper in a melee attack without making it hissing
 * After being hit, Zombies walk very slowly for a few seconds
 * Zombies, Skeletons, Creepers and certainly more will never notice you (even if provoked) if you stand >= 2 blocks upper or below them but they still randomly look at you like a passive mob would would do. --Missingno 26 06:23, 15 August 2012 (UTC)

!! In mp a villager ATTACKED me! Someone tell me why.

! If an Iron Golem takes 3-4 hits from any damage source, Minecarft will freeze. I have not tested to see if they retain the damage dealt before the freeze when i re-log. The only way to get rid of them because of this is perhaps to continually attack and restart Minecraft, or for them to fall into the void.

! Zombies don't even try to kill snow golems, even after being shot. Zombies either don't get provoked at all or can be stunned into submission by a snow golem at close range. I have a zombie that spawned inside the same tiny fenced off area as a snow golem, and the golem was firing more than one snowball a second at the zombie. But rather than ripping the golem's dumb pumpkin head off, the zombie was just standing there and taking it. I have also seen creepers tolerating being shot multiple times by skeletons. --Simons Mith[82.69.54.207] 21:55, 3 August 2012 (UTC)
 * This is because monster infighting has been removed, apparently unintentionally. I've elevated this to Major Bug because of this. Mobs, except for the Iron Golem, Snow Golem, and Wolves, will target the nearest Player exclusively. Zombies will target Villagers over Players. While all hostiles will hold some length of aggression toward hostiles that attack them, this length of time is very short, sometimes less than a second; at this point, both parties lose interest and resume assaulting the Player if he is nearby. Spiders, peculiarly, hold their aggro the longest, making them the only hostile mob capable of killing a Skeleton currently. --GreyMario 23:48, 7 August 2012 (UTC)

!mpTamed Wolves/Dogs: If a player attacks you, and you have tamed wolves, they become aggroed towards that player. They won't stop attacking said player until that player is slain. If the player logs off or is killed, the dogs still growl but otherwise behave like they are not aggroed. However, if they are left sitting down and the player walks away, they despawn as if they were a hostile mob. This is likely because the game thinks they are hostile untamed wolves. Below are a few different solutions I thought of.
 * Add an exception to the despawning rule for dogs
 * Make dogs not attack other players
 * Add a timeout so dogs stop targeting something if they don't get a hit within x number of seconds
 * Make a loop that runs every 5 minutes or so to check if a dog is aggroed, clear target it if is

a World generation and switching worlds When generating a new map, or switching from one world save to another, a lot of invisible underground structures and terrain are incorrectly rendered visible, instead of the surface terrain which should be rendered visible, in chunks near the player, this is really annoying and there exists that the possibility that inexperienced players could die due to fall damage from invisible surface terrain they fall onto due to the surface terrain in chunks next to the player not rendering at all in extreme instances. A temporary workaround is to exit and restart Minecraft every time you generate a new map or switch from one to another to limit this error, however, it is still possible that in some instances surface terrain will still not render properly resulting in chunks incorrectly rendering underground structures.

 * I was short on time and I NEVER post to Wikis. I do not know how it got to lighting either. If you could fix that, i would appreciate it. Also it happened 100% Randomly and nothing can explain WHY i had died. I was redirected from Mojang, so i was hoping they would have experience with this, or at least to know it. And i figured it would be a Major Annoyance due to the fact of DYING in the middle of the water. imagine if that was an Ocean no where near your Spawn. I'll rephrase.

I was moving in a boat near a shore line, -doing nothing out of the ordinary- when i hear the *Crunch* of falling from heights (While still in the boat) and having died. I did not hit anything and most likely there was no Lily Pad to potentially cause this.

Sounds
Bugs

! When Minecraft is started, somehow the sound doesn't play at all for quite a time or the one or another restart, then somwhen just works again and stays this way (Vanilla 1.3.1, Ivy Bridge, Win7 Ultimate SP1 x64, current drivers, Realtek ALC887 HD, JRE 7.0.5 x86 & x64, LWJGL 2.8.4, Sound 100%, Music %). Looked like the system is causing it, but now it's verified on two other machines also. First thought of mute but everything else is playing; this is unique to Minecraft. Maybe a problem with the LWJGL update? This, however, just happens the very first time when Minecraft ist started after a System start (?) and stays away once it fixed itself until the next time it occurs.
 * If you're referring to the calm music that plays every so often, that doesn't start as soon as the game does; it's supposed to take time to play, I believe. --Keithicus420 07:51, 9 August 2012 (UTC)
 * I am also having this issue, and so is my friend. This is three different sound cards so far. A restart sometimes works, other times it makes no difference. And to Keithicus420, it is all sounds across the board.
 * Are you by chance closing the game by using the red X instead of hitting the Quit Game button on the main menu? In 1.3(.1), clicking the red X does not properly shut down the game and just brings it all to a sudden halt, whereas it used to be the equivalent of hitting Quit Game. One of the things that I've noticed is affected is that something goes hairy with OpenAL (what Minecraft uses for audio) and there is a chance the next few times I start up MC again that sound will not work for me as OpenAL will fail to start up. --MWisBest 05:19, 10 August 2012 (UTC)

! There is still an issue with missing pickup sounds, missing sounds for breaking certain blocks and missing footstep sounds on certain surfaces using OSX Mountain Lion. It is possible to fix the sounds by updating LWJGL (2.8.4) but doing so causes visual problems (rapid spinning when entering full-screen and just perceptible flickering). This means either having to play the game without sound or not play at all because the flickering effects causes headaches. --Tseotet 19:37, 1 August 2012 (UTC)
 * Confirmed. I was wondering why it was so quiet. I didn't realize it started after I installed Mountain Lion. I did not try updating LWJGL so I can't confirm the visual problems. 132.203.168.221 04:51, 2 August 2012 (UTC)

 * I can confirm this too. We are getting the same on our server and sometimes sounds are delayed by over 1 second with the "backlog" of sounds (eg. from a line of placed blocks) suddenly arriving in a bunch.  The actual block placement is happening in real time and no issues there, it's just the sound delay.  Our server location is in the next city and we experienced no such issues in 1.2.5 so it's clearly a bug with 1.3 and nothing to do with "servers with a slightly less than great connection". --Rik1301 23:07, 2 August 2012 (UTC)
 * This seems to only happen on SMP servers with a slightly less than great connection. I can't find it on Single player, nor does it happen on the rented server hosted withing the same state as me. It's almost as if the server is controlling the few sounds, block placing, footsteps and eating. Breaking, punching animals all have the timely sound response.

undefined Not so sure if this is an issue with my computer or minecraft but when I enter or exit the nether or the end the sound that is supposed to play on entering the loading screen before you arrive in the other dimension does not play.

a The behavior of the new reordering feature (shift-arrow) in the MP Serverlist is illogical: A changed position of a server in the list is saved only on editing and saving ("Done") any server entry.

The change is discarded when you cancel the editing of any server entry instead, it is discarded also on refreshing and cancelling the list (may be intentional here) but it is also discarded on a server join which will the the most likely action after reordering.

undefined The F3 display of lighting info -- bl / sl / rl -- does not give useful data. At night, outside, it will show bl 0, sl 15, rl 15. Near as I can tell, bl is "burn light" -- how much light you are getting from torches, sl is sky light -- how much light you are getting from the sky, and rl is the higher of those two.

EXCEPT: It's not the game's light level: it's the graphic engine's light index. The moon has light level 4, but still has 15 levels of display lighting (and I can detect about 10 on my computer display).

Result: When the actual game light level is 4, I see numbers of 0 (no torch), 15 (maximum sky), 15 (meaningless result number), and this corresponds to the graphic engine using a 0,15 index into a moonlight table.

Note that this makes RL useless. Torch + sky, for example, will show the same RL as sky alone, yet torch+sky has a much brighter display (And the same game brightness).

In fact, this may point to a flaw in the game's lighting assumption/mob spawning system. The same display brightness given off by a torch (only) at light level 8 might match the display brightness given off by torch+sky at torch 6, sky 6, yet with the same visual lighting you now get mobs. --Keybounce 06:26, 3 August 2012 (UTC)

undefined IME support is (still) missing -- as noted by others previously, too. I think the developers should start to examine this problem, because 1.3 release is a major milestone in terms of software engineering.

I found that the latest version of LWJGL (2.8.4) can handle IME to some extent. I could type Korean characters on Windows, with the following limitations:
 * The completion of a character must be committed explicitly by pressing the space bar twice or using an arrow key, whenever I try to insert a space between words or to press enter to finish typing. This is very annoying for Korean users. (Not sure for Japanese/Chinese users...)
 * I'm not sure this should be fixed by Minecraft or LWJGL, though.
 * Even this flawed typing is only supported at chatting & item search box in the creative mode. Not at all possible with signs & book and quills. The latters do not seem to use any generic text input UI elements.
 * The IME state is not changed after finishing typing, and thus the in-game keys such as A, W, S, D, I do not work. They are delievered as Korean characters to the game even when the user is not using a text box. I had to change the IME state manually to the English typing mode.

On Mac, the character is not properly composed and only the first-typed consonant is actually given to the text box. I have not tested on Linux since I always play Minecraft on Windows or Mac.

I know this issue is hard to inspect for Western developers since most of them may have no experience on character composition systems used by many East-Asian languages. I think http://en.wikipedia.org/wiki/Hangul and http://en.wikipedia.org/wiki/Korean_language_and_computers would help you to understand. Major operating systems such as Windows/Mac have their own IME(input method editor) API and contains a default IME implementation for all supported languages. Linux has a wide variety of 3rd party IME applications for GNOME/KDE GUI environments.

Technically, all text inputs must be implemented to use operating system-provided IME APIs, instead of manually appending individual characters to the value of the text field on key-press events.

So I suggest the followings:
 * Update the LWJGL library distributed with Minecraft to its latest version.
 * This should enable the limited possibility to type East Asian languages at least.
 * Since Minecraft is one of the most popular games implemented on top of LWJGL, I or you guys could request the IME issue as a major consideration for their next releases.
 * Use a generic text GUI element for every text inputs, including signs & book and quills.
 * Disable IME when no textbox has focus, to prevent unintended translation of keys for the gameplay (e.g., A/W/S/D/...) by IME.
 * This is a common operation in Korean GUI applications: the IME is disabled for the password input fields, which may confuse the users by allowing Hangul passwords and denial of service due to differences of IME settings in PC to PC, for example. All Korean PC games automatically turn on/off the IME depending on the context.
 * Expose a modding API that enables customization of text inputs.
 * It should feature a live display update callback like Windows IME API to show intermediate composition process to the user, aka "on-the-spot" IME.
