Minecraft Wiki:Issues/1.2.5

Crashing/System
!! My Minecraft was working perfectly fine a few days ago. I can play on my browser but now when I try clicking on the icon on my desktop, it just lights up but no login screen appears. I have everything up to date and have Windows 7. There aren't any crash reports.

! Randomly when I am playing my Single Player Survival Mode the game glitches and locks up. I have re-downloaded MC and I have the latest update to java. The issue is, when I log back into MC (which I have no problem doing) my world is gone. This has happened to me twice now. All of the data that was in use was erased so my world disappeared from my world list and files are missing in my .minecraft/saves folder even though my worlds still are listed. The first occurrence was when I was chopping a tree I got a green screen and my computer locked up. The second occurrence was when I was opening a double chest and I got a grey screen and my computer locked up. Both times after I had to restart my computer my world files were erased. I have updated to 1.2.5 and have no issue logging into minecraft. I have no idea how to recreate the event since a crash log wasn't generated nor was there any specific instance where the error occurred because due to a specific trigger. ld !! After downloading the Minecraft.exe file, and launcing it, the game stops downloading. After a while it says "Fail to launch. Fatal error occured (4): connection reset. I have tried to reinstall Java 7 and disable firewalls. I have also deleted all previous Minecraft files but nothing have worked.

!! If I go on this one sever it will say its loading for a few moments then give an black scren with a split-second error then just stay black I cant close it untill it hits the black screen I played on this sever many times including just before that crash I turned the pc on and off and opened minecraft over and over! this bug happens sometimes and stops but now it crashesh on the sever all the time help! -gregdsi

!! Strangly, I am incapable of deleting any worlds. Because of this, my game crashes often, due to memory being too low.
 * How about you go into the .saves folder and delete the world files?

!! Upon starting Minecraft, the game instantly closes itself without an error log.
 * Specifications of your machine please. (As well as what Java version you have.) Iyeru 15:35, 16 July 2012 (UTC)

!! Sometimes, when joining a server with high traffic, minecraft will crash with no log. Your mouse will not show up for a few seconds, and clicking X will not close minecraft. You will have to FORCE QUIT minecraft in order to close it. --Blackbird626 12:41, 13 July 2012 (UTC)

! Sometimes, when joining a multiplayer server, only a few chunks will load, and ALL MOBS AND PLAYERS are stuck on your screen. You will get a "Read timed out" error. If you quit minecraft, you have to WAIT A MINUTE before minecraft works again --Blackbird626 12:41, 13 July 2012 (UTC)

!! I turned my computer on this morning and went to a SMP server. I tried to chat and when i did minecraft crashed! crash report for a sec that WALA black screen. TESTED MULTIPLE TIMES when i try other servers it just crashes but no black screen.... it is the brown screen that you get when logging in but with no Logging in or Polling.

!! On OS X 10.8 Mountain Lion, Minecraft will not launch unless Allow Applications download from Anywhere is selected in the Security & Privacy System Preferences. If "Mac App Store and Identified developers" is selected, the error message is: Minecraft is damaged and can't be opened. Changing it to Anywhere allows the program to launch without error.
 * Not a Minecraft bug; this is how the OS feature is intended to work. -- Orthotope

!! On Ubuntu 11.04 with GNOME 3 Desktop, trying to open fullscreen crashes the game and leaves the screen unusable and can be only fixed by a hard reset.

!! There is a MAJOR bug with this network card. Its the NETGEAR Wireless PCI Adapter WG311v3 Rev. A1. When logging in to any minecraft server using this network card about 30 seconds in to the game or when the client breaks a block it will crash and windows will instantly quit displaying a Blue Screen Of Death. I think this bug happens only with this network card but i haven't tested it with any my other NETGEAR cards.

!! Whenever I try to enter a Single player Creative server, I get told that Minecraft has no memory left and I get kicked out. This started happening after Minecraft crashed once.

!! Every time I try to play a minecraft version lower than 12w21b minecraft crashes with this report:

undefined When the world names contains COM, it will be saved as _. Ex: COMBAT will be saved as _BAT.

!! Pressing tab crashes my client most of the time.
 * That probably happens when people in multiplayer use colored names in the tab list or change the text style. --Tom3445
 * Occurs in singleplayer as well. While it wouldn't be a problem for most players, I'm still used to games like Skyrim showing me my inventory when I press Tab. Removed the MP tag.

!! When I attempt to mine gravel with an efficiency 5, Fortune 5, unbreaking 5 diamond pickaxe, the game crashes. This is in singleplayer survival. I reopened Minecraft went into another creative world and enchanted a diamond pickaxe, among other diamond tools (all low-level enchantments), and couldn't reproduce the crash there with any of the tools. But I can reproduce it back in my survival world. (Add: I've got the same problem, all enchanted swords will crash the game if you try to kill a mob with it. A blank sword works fine.)

!! Whenever I shoot a bow, Minecraft crashes, on both multiplayer and singleplayer including creative.

!! If you open a world where you have died and maximize the window, you can't press the "Respawn" button or the "Title Screen" button so you have to close your Minecraft. --electronic90009@live.ca

!! When I open Minecraft and play it disconnects me from my internet... I am not sure why... =?

 * You're using Fortune 5 on gravel. When Fortune is used on gravel it increases the chance of dropping flint. Fortune 1: 10-20%. Fortune 2: 60%. Fortune 3: All gravel drops flint. Any higher levels of Fortune will incorrectly calculate the probability and crash your game. By the way, this is an enchantment you cannot get in vanilla. --124.180.239.131 09:41, 23 June 2012 (UTC)

 * ZOMG!! Same thing. Able to recreate. EVEN BY STARTING MINECRAFT I GET THAT!
 * so that's what my friend was talking about

!! When playing a custom map that involves the void (like skyblock or 4 pillar) the game will crash whenever you look at a map. Can be reproduced by downloading skyblock or others like it with an open void and looking at a map. May have something to do with the map not being able to show the actual void. Can also render a world unplayable since having a map in your first hotbar slot will crash the game every time you log in. Played with no mods or modded items.
 * I'm pretty sure that I have duplicated this bug. I'm also in a custom map (The Tourist) and after I finished playing, I switched to creative mode and started exploring with a map, but the game crashed with this error. At the time I didn't know that I was near the void. The error would only appear if I looked at a map that showed my current location. undefined 75.39.130.64 15:43, 6 July 2012 (UTC)NanoExplorer

 * Update your video card drivers, if doesnt work then you HAVE TO get new Video Card.

! Occasionally when traveling though a nether portal, after taking a longer than normal time to try and load the overworld, Minecraft crashes and gives an error message. This is annoying because though the world is intact all the items in your inventory are deleted. Have had this problem on both survival and hardcore but mostly only when the saves folder holds a lot of data.

!!? Sometimes, when saving & quiting from a world, the background will resize to a very small bit in the corner of the screen, causing the player to have to restart Minecraft. I beleive it happens the most when saving, then immediatly minimizing Minecraft and going to the desktop or another window.

!!? Pressing F3+s crashes the game.
 * Reproduced but it freezes the game instead of crashing it. In order to close it you have to kill the javaw process or whatever your minecraft process is. --Tom3445

!! When attempting to log in to a Minecraft server after migrating an account to Mojang, the client will crash. It will then show an error for about half a second before disappearing to black again. This error has occurred for the past three days. (I have tried force updating, doesn't work)

undefined No Squid Sounds.

undefined F3 pie chart is usually dominated by "unspecified".

!! We have a Minecraft server that has been in use since the 1.8 Beta. Shortly after updating the map file to use Anvil, a random chunk refused to render and started spawning thousands of creepers, eventually crashing the server. We blocks away, this time with skeletons. We also deleted that chunk and restored the area to normal, but I'm not confident that it will not happen again. The player who reported issue the first time has noticed that his monster spawner trap becomes many times more efficihad been running the server on peaceful mode for a few months and recently noticed that MCEdit was updated with some compatibility with Anvil. A few days ago, we deleted the offending chunk, forcing it to regenerate, and that area returned to normal. We thought the problem was fixed, but today the same thing started happening in another chunk a few thousand ent when there is no one else logged in, and the issue recurred near another player while he was the only one logged in. Obviously, monster spawners don't spawn creepers, so it's probably not the monster spawner themselves, and I don't think it necessarily has to do with using a 1.8 Beta map since the affected area have been active locations for days before the issues surfaced. 98.113.63.61 04:22, 24 May 2012 (UTC)Omar

!! When playing Minecraft and using VLC to watch movies (dual screens) my computer will sometimes completely freeze. The screens go black and the sound plays in extremely slowed sound bites. The only solution is to give my machine a hard reboot. My assumption is that both programs try to grab the same hardware resources, which cause a hardware level problem. I own a 2010 MacBook Pro, i5 M520 CPU, nVidia GeForce GT 330M. This error has occurred consistently for the past week (I just started playing again.)

!! When a player is killed by a fireball fired from a dispenser, it causes the server to crash.

! Sometimes, chunks reset completely, deleting all user placed blocks, destroying houses and other structures up to the top layer.

! when I start to play the game it runs for a while before stopping, saving chunks than producing a screen saying 'Minecraft has run out of memory' (it claims it may be a bug, but might be a memory problem.

 * Same problem for my son. Playing on a server causes that screen very often ;( (08:00, 18 June 2012)
 * Try to set your render distance a little lower. You may have it set on far while using 32-bit java. If you are on a 64-bit system, install 64-bit java if that was the case. It should fix the problem so you can be on far render distance and also have enhanced performance. --Soup420

!mp Shift+Click behavior occurring when not holding shift while within: Inventory and Chests [Survival] and Item Menu [Creative] Moving them automatically to a free spot [Survival] or giving you a stack of the item you click on / inability to move item from the hotbar. [Creative] KHRoxas 16:56, 10 April 2012 (UTC)
 * watch SethBling's vid on bugs, the shift key sometimes gets stuck, happens to me on survival, try optifine with "SMOOTH INPUT: YES"
 * Incredibly unhelpful response, you need to press the opposite: "SHIFT" key. (R-SHIFT). That will fix the complete problem for you.
 * Make sure you don't hit Alt while holding shift. If you hit Alt while holding a key in Minecraft (for example, moving forward) and hit Alt, the game will freeze and your mouse will be stuck. When you click again, the game will unfreeze, but whatever key you were holding will be stuck. Hitting the key again will fix it. Tested in Beta 1.7.3 (using You Are the Creeper, not updated) but has been happening to me since I got the game, modded or not.

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

! If you have a superflat world from 1.1, dying will delete ALL OF YOUR CHANGES!!! Possibly because of the Anvil conversion.
 * I think the problem is that superflat worlds don't have a set spawn point so when you die, the game picks a random spot to respawn. Your changes aren't deleted, but unless you pressed F3 at some point before you died, it's near impossible to find them again (in which case, use something like MCEdit to find them. This problem has been around since the Superflat world generator was added. NetherrackCreeper (talk) 19:57, 18 April 2012 (UTC)
 * Here's the real issue. It DOES save everything AND your spawn location. Minecraft is weird in a way. If you are spawning below 64 blocks (In superflat it's only 5) there must be a block at 64 blocks. If this is not true, Minecraft creates another spawn location and overwrites the old one. I heard about this from mcedit. And it's true, I've tested it. RyanDolan123 03:34, 1 June 2012 (UTC)

undefined mp Labeled as Fixed on the 1.2.4 bugs page, still exists for me: After executing a command in the chat box, Minecraft will not exit the entry box thus the player is stuck in talking mode. Entering another command or text will, on a few occasions, give the opportunity to exit text mode. In most cases anyway, it will write another line beginning with a slash.

EDIT: EDIT: EDIT: (I know spam, but this is important): THIS IS AN NVIDIA AND MINECRAFT PROBLEM! I ran Minecraft with Intel Integrated Graphics blabla (because on other computers that's what they used and it worked) AND IT WORKED!

Just because it worked on another computer doesn't mean its a hardware problem.

I think it could be the fact that in the code, Java can use variables up to a certain number, then crashes. In this case, the maximum is 3, and after that the number becomes negative. It is the fact that code CANNOT have negative numbers in it that crashes the game. There IS code made in the startup of the world to store data in it, and once it loads the tool with a negative number enchantment, the game crashes.

Minecarts/Boats
Bugs

! When moving in a certain way, minecarts can randomly derail themselves from curved tracks. Yes, minecarts can fly off curved tracks, even though there are no gaps in the track. No entity blocking tracks. PLEASE FIX !!!
 * Happens to me too. I have only tested on SMP and only with a entity blocking the tracks.

19:03, 25 June 2012 (UTC)
 * I've only had this happen when multiple minecarts are stacked and moving far faster than they should be: Apparently they move diagonally by more than a block width and derail. Not so much a bug as an annoyance. Skyboy 03:31, 6 July 2012 (UTC)


 * This can be fixed by placing blocks next to the curves, preventing derailing.

! If a mob hits you while in a boat, sometimes it will do severe damage or kill you. This happened to me in my singleplayer world when a squid was in 1-block-deep water and I traveled over him in a boat. It was also captured on video (multiplayer) here (@ 20:04) with wolves (the wolves were following the player and they teleported when the player got too far away). I think it happens when the mobs come up from below you. Both SSP and SMP affected. --Arcooke 02:02, 5 May 2012 (UTC)
 * Confirmed in SMP with a zombie coming up under the boat. There appears to be two other issues with this bug.  The first is that it always appears to show that the player died from falling too far.  The second, which is more problematic, is that it appears that this causes the users spawn point to be reset to the world spawn point, possibly putting you far away from your current location even if you have bound to a bed near where you are (The bed in question is still intact, has not been moved, and is in a viable spawn location).  Pewmayman 14:57, 7 May 2012 (UTC)

x mp When a boat is placed where water is moving/pushing it from behind and there is a solid block in its path (examples: stone, door, cobble), the boat will 'move' through the solid block and continue forward for about 10–15 seconds then 'rubber-band' back to its original (actual position). It may be that the client is predicting movement that is not actually happening (and is corrected by the server every X # of seconds). This is a major annoyance in trying to build things like docks, which may hold a boat in place until called/let loose 78.147.230.170 14:37, 13 June 2012 (UTC)
 * This seems to happen with other pushed entities as well. This rubber-band effect can be observed when mobs push other mobs.
 * Had this happen to me as well with a simple boat dock I made. 3 pressure plates hold back water from entering the dock.  When the boat enters, and lands on the ground, the boat continues to "drift" slowly, as if it were still on water.  Then when I exit the boat, it makes a duplicate of the boat.  The boats, when bumped, bounce around the dock and move into blocks, then rubber-band out or break.  This does NOT happen in Single player.

undefined A minecart going up a properly powered narrow spiral track will sometimes get stuck on the blocks when it is cornering, depending on where you have the camera pointed. The only solution is to remove the minecart. This does not happen on the way down.

undefined cr Sometimes when a minecart carrying a mob is traveling on a track it may get stuck on buttons or powered track. They do not decelerate as they would normally on an unpowered track but rather just stop. This has happened only rarely and only on creative with lots of redstone wireing around. I have found this with all the mobs I have tested but not with the player. I have not found this problem with spirals or corners more than other places and the stuck minecraft could be pushed again after a few tries as it repels the player but with persistence it can be done.

It may be the caused by a current in the water, as I made a system of flowing water blocked by pressure plates to travel faster. Unfortunately I have not been able to reproduce this. Sorry :/ This was on Windows 7 64-bit, playing survival mode on normal difficulty.

Annoyances a! Landing a boat onto slabs causes fall damage. When trying to recreate it, I only took one heart of damage for several different tries.

a! mp In multiplayer, other players in a boat or minecart often appear in the running animation. This is definitely a bug, the players' feet stick out the bottom of the vehicle.

Redstone/Pistons
Bugs

undefined when fire charges are fired from a dispenser, if the game is exited while they are in flight and then re-opened, they will apeer as ghost images in mid air, not moving but with their flame animation still active and unable to be picked up or to hit objects and burn. blocks can be placed over them and they will not set fire to them or disapeer. when the game was re-started the charges carried on for around 5 blocks, decelerating rapidly to a standstill before becoming such "ghost" images. After using a fast repeater circuit with a dispenser and fire charges, most fire charges hit a forest but some continued beyond the render. when game was re-loaded, a large veritcal and horizontal wall of fire charges had appeered along the x and y or z and y axis a few hundred blocks to the left of the dispenser. these responded just like the charges that had been caught mid-flight. these ghost images are ruining my creative project and I hope that not only can this be prevented but also that I may be able to remove the images form my world.

! Sticky Pistons, when updated quickly enough, will replace the block they're pushing with their arm, effectively deleting it. This seems to occur when the piston is powered just as the piston is finishing retracting, it will extend again before the entity is converted back into the appropriate block. Since pistons are slowed in 1.3pre, this shouldn't occur, but it would be nice if they could keep their speed.

! Pistons not retracting correctly: Say you have 4 pistons, stacked on top of each other like this:

A

B

C

D

Power each one individually. Make sure you are powering only one at a time. Powering D, then C, then unpowering D will result in D extended, but not powered. Powering D, C, B, A, then unpowering D, C, and B in that order will result in all being extended, but only A being powered. PLEASE FIX AS THIS BUG RUINS TELEVISIONS !!!

! When a redstone torch burns out, it might be permanently burned out. Replacing the torch or the block will result in the torch burning out on the first powering. PLEASE FIX !!!
 * Confirmed. This is so annoying! RyanDolan123 16:02, 11 July 2012 (UTC)

! Newly-placed Pistons will automatically extend if there is already an active power source, such as a Lever that has previously been switched on, TWO blocks ABOVE where the Piston gets placed even if there is NO block just ONE space directly above where the Piston was placed. If the power source is deactivated or removed, the Piston will remain extended unless there was a block directly one space above where the Piston was placed.

This problem does not exist if the previously-activated power source is two blocks away in other directions (to the sides, or from underneath) when there is one empty block space between the previously-activated power source and the newly-placed Piston. It only happens if the previously-activated power source is TWO block spaces ABOVE where the Piston is placed with the empty block space directly in-between.

TO REPRODUCE:

(1) Place a Lever on the side of a block three block spaces up so that there are NO blocks in either of the two spaces directly below the lever itself. (2) Switch the Lever ON so that it is an active power source. (3) Place a Piston two block spaces directly down from that previously-activated Lever (there should be one empty    block space directly between the Lever and the Piston). The Piston automatically extends even though it should not. (4) Switch the Lever OFF so that it is no longer an active power source. Or, just remove the lever. The Piston will stay extended.

EXAMPLE (SIDE VIEW):

--- --- |              |               | |               |               | |     Solid     |    Lever      |  (1) |              |               | |     Block     | (Switched ON) |  (2) |              |               | |               |               |  --- --- |               |               | |               |               | |    EMPTY      |    EMPTY      | |              |               | |    SPACE      |    SPACE      | |              |               | |               |               |  --- --- |               |               | |               |    Place      | |   EMPTY      |               |  (3) |              |    Piston     | |   SPACE      |               | |              |    Here       | |              |               |  --- ---

If the block space in-between the Lever and the Piston was not empty, the Piston would have retracted as normal in step four. Regardless, the Piston should NOT have automatically extended in the first place since there was just the one empty block space directly in-between the Piston and the Lever.

Some slight modifications need to be made to the steps above to compare the behavior when the active power source is two blocks to the side in any direction. Instead of using a lever in that situation, you can use previously-powered Redstone Wires instead. You will see that the Piston (again, TWO blocks away with an empty block space directly in-between) will NOT automatically extend when it is placed. However, if you have a solid block in-between (with no spaces), then it will still automatically extend as is normal.

The problem occurs when there is an EMPTY block space directly in-between the already-active power source and the newly-placed Piston when the already-active power source is TWO blocks ABOVE where the Piston gets placed. The Piston should NOT automatically extend unless there is a solid block between the Piston and the Lever.

IMAGES:

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

The block that was from the piston that disappeared was probably block 36.

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

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

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

undefined When standing above water, breaking a block underwater does not show the breaking animation.

undefined Leaf blocks leftover from alpha don't decay when disconnected from wood. This problem existed before and was solved, but exists again in 1.2.5. Problem typically resurfaces when changes are made to leaf blocks, like when decorative leaves were added, or new tree types.

undefined In single player survivor if you do this in order you can duplicate an item as you want.
 * Throw down as many items as you want (Q button) DO NOT PICK UP
 * Hit Esc, then click Save and Exit.
 * Re-Enter the same world
 * Pick up the items
 * Exit the game by hitting the X at the top right corner.
 * Re-Enter the game again and you will notice the items are still where u dropped them but the game also acted like you picked them up.

Essentially you can duplicate anything in the game very easily.


 * Something like this happened to me and a friend on an SMP server. The host "dropped the server" because of bad internet or whatever. The next time I went on the server, a lot of stuff got duplicated. Me and my friend both had the same problem but we figured out what happened: The game loaded us to the last time we saved (or pressed "ESC", since it auto-saves for you). I had an inventory on stuff I just mined at that time. I put it all in a chest, and after the server went down and was fixed, I had everything I mined in my inventory AND the chest (the game saves what's in the chest (since it's part of the game) but not what's in your inventory at the time of the crashed server). My friend had crafted an inventory full of iron pickaxes and stored them in a chest as well. He ended up with a double-chest-full of them. What we think happened was that the terrain was saved (proven since the host had put coal in a furnace and it was still there, even though he didn't save), but not our inventories.Bobbychan193 08:52, 20 July 2012 (UTC)

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

 * Similar problem occurs when transitioning from any type of fence or fence gate block to the above (i.e. a fence placed one block level below also acts a block with halfblock height and will also cause this temporary glitch to occur)

a! The enchanting system has always, and continues to be frustratingly unfair. sometimes producing Efficiency III when a level 50 enchant is used. Considering you need to kill NINE HUNDRED AND TWENTY FIVE zombies/creepers etc., to get to Level 50, users are naturally in consensus that, to quote Yahtzee Croshaw, the ratio of difficulty to find versus actual usefulness is completely arbitrary. While we respect the mystique Mojang have tried to create about enchanting, the numbers need serious review. Kizzycocoa

Bugs ! Here's an example of my bug: Lets say you slept in a bed in your house. Then you go outside with low health and you turn around, greeted by a zombie saying "Hey wassup bro?" The game has a reasonable amount of lag and he kills you. But when you respawn, you don't respawn in your bed! You respawn on the top of a mountain nearby, and no it doesn't say "Your home bed was missing or obstructed." I was able to reproduce this bug plenty of times. It got pretty annoying, and that's how this bug report ended up here.

a! Relating to the Above Topic i have also noticed that placing new nether portals near existing stable portals can cause the existing link to break and reform in the wrong location

a! In single player survival mode, some structures vanish after logging out/quitting, however the any items the player has remains in their inventory. This has happened several times to me, where I have built a house etc. and then logged back in to find it has disappeared. Unusually some structures have survived in some worlds of mine but others have been completely removed in others. I have no mods installed and same effect happens no matter the texture pack (including default).
 * This sounds like the chunks being regenerated from scratch, possibly due to a write error.  --King Starscream 21:29, 7 June 2012 (UTC)

a! If you have any Structure above you below y=64 the sky immediately turns black. Especially annoying and unavoidable on a superflat map. Building a house and looking out of the window - just pitch black darkness out there. Wandering under trees with fast graphics makes the sky flicker between black and normal. (Not sure if it's a bug.There's no scenario in which this would make sense. Even if I'm underground, if I see the sky, it's still blue.) Also happens in creative, so not related to the much more annoying and much less sense making void fog.
 * I have to second this.The Effect is called "Dimming".A server I play on requires a Mod which removes it together with the void fog (big buildings)
 * Void Fog and Dimming should not appear in a superflat world but it happens to me too.Can someone confirm this? 93.128.59.12
 * I can.This is definitely a bug.Maybe we should make an extra point for it.

a 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.

a Once entering a bed, the character will slide off and fall on the floor, but will sleep normally.
 * I think I see this too, and I think it's a bug. Try rotating the bed 90 degrees and see if you slide down it rather than fall out. I have one bed in one game where I fall out of bed (to the side) and another where I slide down the bed but otherwise sleep OK. Also try a room with a 3-high ceiling throughout. Both of my buggy beds are in rooms with mostly 3-high ceiling but only 2-high at the edges, and the beds are next to the edges of the room. Does what I describe match what you see? 82.69.54.207 02:32, 19 April 2012 (UTC)

a! mp When blocks are removed by Creeper explosions, jumping into the crater will result in an infinite fall (You will appear to fall onto the block, but you will teleport up 1 layer in an infinite loop)
 * This is due to the client failing to obtain the world data after the explosion. The glitchy up and down infinite loop is because of this: The client sees a hole, you can fall in. The server knows there's blocks there. You fall in. The client keeps thinking it's just an empty hole. The server repeatedly tells the client you can't move there. That's how! Disconnecting and reconnecting usually if not always fixes this. RyanDolan123 04:31, 1 June 2012 (UTC)

Bugs undefined Villager breeding can be uncontrolled, see rTiE-gZ0BBw on youtube (this thing won't let me put the link here) Because the algorithm for finding doors in Villagecollection.addNewDoorsToVillageOrCreateVillage is:

int j = (int)village1.getCenter.getEuclideanDistanceTo(villagedoorinfo.posX, villagedoorinfo.posY, villagedoorinfo.posZ);

if (j > 32 + village1.getVillageRadius)[...]

And the method for determine population in Village.updateNumVillagers is:

worldObj.getEntitiesWithinAABB(net.minecraft.src.EntityVillager.class, AxisAlignedBB.getBoundingBoxFromPool(center.posX - villageRadius, center.posY - 4, center.posZ - villageRadius, center.posX + villageRadius, center.posY + 4, center.posZ + villageRadius));

there will be a possible mismatch between the apparent door radius and the apparent villager radius. Since the center of the village is mostly door dependent, if people build doors high off the ground, the center of the village will be higher then where all the people are, and numvillagers will always be 0 or 1, leading to out of control breeding. --4.30.62.18 18:42, 21 June 2012 (UTC) A!

! su mp Golem/tamed animal to player behavior in SMP. Major coding omissions here specifically in SMP. There's a few issues to address and some suggested solutions. --Bronzedigger 4:32, 3 May 2012 (EST)
 * Golems created and animals tamed by a specific player will not defend themselves against other players who attack them. Additionally player-created golems and tamed animals will not defend their master when another player attacks said master.
 * I suggest a simple GUI interface added to the page shown when holding the tab key which lists all players online and their pings. There could easily be a check box added for an identify friend/foe system in which golems and tamed animals of the player would adhere by. In this method a player could declare who is a friend and his golems could assume others to be hostile, thus protecting his land and himself.
 * Minions created by player 1 should be also be hostile to minions created by player 2 if player 1 has played 2 marked as an enemy via the IFF system.
 * After the above solution is implemented there is still the matter of telling to who each minion belongs to. This is not so much an issue with tamed pets as they obey commands. Golems, however, are completely identical to one another. Therefore to tell them apart I propose additional skin slots located at http://www.minecraft.net/profile which could be used to upload a player's own golem skins so player 2 who is enemies with player 1 does not approach player 1's golems thinking they are his own and get clobbered.
 * Marking this as major because current minion behavior is perfectly fine in singleplayer, but a major oversight when the multiplayer aspect is added. Needs to be changed. Anyone who has played unmodded SMP knows that invariably not all players are friendly. Player minion mobs should be tweaked to follow suit.

! Nearby (100-200 blocks) dogs/cats teleport to you, even they are seated.
 * Specifically I've noticed that previously sitting cats and dogs teleport to you as soon as you get in range.
 * Cats and dogs teleport to you at unpredictable intervals. Sometimes they don't for a while, then suddenly there they are.   Zorrothefox 15:06, 16 April 2012 (UTC)
 * I tried reproduce the bug in a new world (generated in 1.2.4). No problem with this. Maybe a bug with converted worlds (pre 1.2.3).
 * Another case: (various users)
 * Confirmed that this happens in both single and multiplayer survival.
 * Untamed wolves and ocelots follow me and teleport. This is very annoying as trying to do anything on the ground you will probably hit a wolf and make them hostile.
 * Confirmed. It seems that when I enter a wolf's line of sight others teleport to it, as normally more than 3-4 wolves don't spawn. Unpleasant.
 * This has been annoying me for a while. I'm pretty sure it started happening around 1.2.4 or 1.2.5. I keep about 25 dogs/wolves and 5 cats seated in a big room under my base in SMP. Usually while returning to the base (maybe when the unloaded chunks are loading?), they ALL suddenly warp to me. Extremely annoying if I'm in a 1-block-wide tunnel because the dogs push me around and it takes a very long time to get back to the surface. StalePhish 14:52, 17 April 2012 (UTC)
 * Not to go on and on about this, my experience is much like that of StalePhish. I too keep a lot of dogs and cats, and they were formerly in different locations (this is SMP).  Now I have to keep them all in one room (because they all end up there anyway) and having all of them suddenly warp to me at unpredictable intervals is annoying and dangerous.  It's making the game nearly un-playable.  Zorrothefox 12:38, 19 April 2012 (UTC)
 * Definitely happening. And since recently I've been exploring farther and farther distances because I've gotten in the mood to explore new areas, when I return home, all my dogs and cats spawn on me. This is a huge huge problem, because I happen to like netherrack and setting it on fire for light and there happens to be no code for dogs or cats to stay out of the fire. Even mobs will not jump on a block that is on fire, but dogs and cats will. I've been losing pets left and right.
 * The problem seems to occur when you go out of range of your cat/dog so that the chunk holding them saves. When you reload these chunks, the pets are reloaded but the teleporting code probably runs before the sitting code, so a sitting cat or dog will suddenly appear beside you when you reload the chunk they're in. 124.180.239.131 12:16, 6 July 2012 (UTC)

! mp Mob movements are glitchy in SMP, leading to the following issues:
 * In a pen farm animals will appear to jump over their fences, and wander out; if the server does not shut down, they will be pulled back into their pen like a laggy teleporting player. However, they can also "jump" onto the top of the fence. While up there, they will spin around, and eventually come back down on the proper side. If the server is stopped while a farm animal is on the top of a fence post, then on server restart they ARE on top, not "tied" to the inside side of the pen, and after spinning around can walk off to the outside of the pen. I tried making fences at height 2 instead of height 1 .. Keybounce 08:24, 5 April 2012 (UTC)
 * Captured animals (also mobs) seemingly appear outside 1 block thick 2-3 block high room (like they were getting out), mainly the roof. If there is no roof they appear top of 2-3 block high wall. You can collide these glitching animals. (pics from 12w04a)  -88.194.211.57

(Maybe he didn't read the wiki....) Other possible factors: the other two mooshrooms seem to have been lost by a save game glitch.

Bugs

!Sometimes, when exiting minecraft while in the end (with a live enderdragon), when you load the world, there are multiple enderdragons (tested in SSP creative)


 * I tried this, something else happened. The enderdragon froze, the health bar was at 0, and then nothing happened until I loaded the chunk that it was in and it continued to fight me. Anyway, why is this a critical bug? It doesn't crash the game. Partonetrain


 * Confirmed. What is SSP creative (Survival Single Player creative? Is it survival or creative? I tested it on creative)? Changed to major bug, not critical since the game doesn't crash. --Bobbychan193 12:14, 20 July 2012 (UTC)


 * Another bug, along with the one above, is that whenever you kill one, one "dragon egg monument" and portal appears (example: there are 4 enderdragons. You kill them all and there are 4 said "monuments") --Bobbychan193 12:14, 20 July 2012 (UTC)

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

! mp If mobs are confined in a small area without any chance to leave, they often break out if the chunks get unloaded and then loaded again (relog,entering portals). This can be very annoying when collecting Mobs for XP farms or iron farms.
 * I don't think this bug is confined to keeping mobs just in small areas. In SMP, I have several large fenced in areas for cows, pigs, and chickens (each is about a 20x20 area). Additionally, I have an 8 floor building, each floor containing two pens of sheep (all the dye colors). When I quit (and stop the server), all of the mobs were in their proper places. When I start the server, and join, at least one cow, one pig, and several chickens somehow make it out of their fenced in pens. Additionally, when I go through the sheep building to take a roll call, many are flat out missing. I'm guessing the sheep somehow glitched through the walls. This is VERY annoying to have to upkeep the numbers on my farm animals just because I can't keep them in their areas. Supposedly this was fixed in 12w04a, but it doesn't seem that way. I consider this to be the single worst glitch in Minecraft. Someone please fix this. --EcH0 MaTRiX 15:21, 20 July 2012 (UTC)

! mp Mobs do not spawn at a certain height is smp. Even with all chunks loaded mobs will not spawn. I'm unable to find the exact spawning height, however I do know that mobs will not spawn at 230+
 * Actually, it's 240. Or more accurately, mobs won't spawn within the highest 16 meter section that has at least one block in it. This is because the game tries to not spawn mobs above the highest section, but it uses the bottom of that section as the limit instead of the top. I'm not sure why that check is needed at all since mobs won't spawn in the air anyway. Last username 11:18, 11 April 2012 (UTC)
 * Mobs will still spawn as the result of sieges however. I have an iron farm set up above 240 in SMP and zombies still spawn periodically with standard siege behavior.--Veedrock 11:36, 7 May 2012 (UTC)

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

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

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

undefined Mobs sometimes "spin". I'm speculating here that this is the result of the AI Pathfinding attempting to move the mob and not finding a suitable path. Easily reproducible by pushing/dropping/having mobs (namely villagers) move on top of fences, but there may be more complex cases such as when a path node is no longer navigable due to a dynamic terrain change, or unexpected terrain behavior such as falling through cobwebs (which does a complete spin, as opposed to a short circle). As another example, I have also witnessed pigs run in circles trying to get away. Whether it was attempting to get into a 1x1x1 hole and failing because it hit perfect orbit or could not run away in the jungle, I'll never know.--PlNG 00:17, 29 May 2012 (UTC)

mp Attempting to feed wheat to a large herd of cows in a pen: Cows will typically eat two wheat per cow.

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

a If you attack an aggressive mob with something that launches them far away. They keep on walking until they get to you and attack you. They will still be going even if it is more than 16 blocks away.Punch trees, get wood 21:31, 9 April 2012 (UTC)

a Please fix "shadow mobs": Mobs that spawn inside the player's protective radius and then are immediately removed. This frequently occurs while quickly removing material such as dirt or quickly removing dynamic material like gravel and sand. Occurs on all difficulties, all light levels (even surface, sun, midday), even on Hardcore. Called shadow mobs because they do not have any lighting applied to them and are removed before the game lights them. Happens often enough to cause a nasty flinch.--PlNG 05:12, 12 May 2012 (UTC)

a There shouldn't be a limit to how fast experience orbs can be picked up. For example, if you kill 100+ mobs at once (ex: using a splash healing potion on a zombie dungeon spawn trap), you have to deal with almost 2 minutes of yellow/green flashing light as you absorb the XP one orb at a time.

a Performance issues affecting peaceful and hostile mobs. Basically, having large numbers of mobs slows machines down, and clients in multiplayer. The worst affect seems to be when mobs are right at the edge of "client range". However, a test with 21b where the "server side" died, and the "client side" kept going, showed that that same machine had great performance with no mob updates.

In other words: The behavior seems to be "Send all mob information to the client every tick; have the client update a lot of information all the time", regardless of whether or not it is needed.

Idea: First, a peaceful mob not in line of sight is of very low priority to the client. A hostile mob in line of sight is of high priority. In general, the server won't know where the client is looking, and cannot tell line of sight of the player easily, but can tell line of sight of the hostile mob, and if the hostile mob has aggro on the player. Based on this, you can have the server update mobs based on things like:
 * A) In the same 16x16x16 mini chunk
 * B) In an adjacent one "close by"
 * C) Has line of sight for long range
 * D) Has line of sight for mob's range
 * E) Has Aggro
 * F) Is hostile / neutral / peaceful (neutral == things that are peaceful now but might become hostile: pigmen, wolves.)

Note that an entity at very different heights, with no LOS is not of interest, but it might fall to your level and in front of you; changing the condition of a mob may result in it being forced to be updated, in much the same way that Optifine forces the chunk you are in to be updated "now" while other chunks are updated smoothly.

Bugs a!When I was playing my survival map (4 pillar survival), I killed myself to replenish my food bar. When I respawn, I start falling out of the sky into a world I've never seen before, having the world end abruptly and having flat sides. Is it possible to get back to my 4 pillar map?

undefined Super flat maps from 1.2.5 if you convert them to 1.1 (technich pack) the hole world restarts. Help it was my main world with lots of vreations and my calculator!!!!! Please help me!!!!


 * Downgraded. It doesn't crash the game. Below is an exception because it's worse than a crash . Partonetrain

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

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

! sp If for some reason, the game deems the location of the End Portal in a stronghold to be unsuitable due to excessive generation / conflicts, it ?moves the location of the end portal?, however it does not update the Eye of Ender's coordinates.

 * My portal was cut away by new terrain generation. Tried to delete chunks using MCEdit, now the ender eyes lead me to a point where's no stronghold and no portal.

undefined When converting a world from 1.1 to 1.2.5 (to Anvil), some chunks appear to be old, some buildings are missing. Maybe related with mods (in 1.1 OptiFine and TMI, in 1.2.5 only OptiFine A9), but i don't think so. --Galaxy_2Alex (Talk)
 * DO NOT post bugs that were possibly from mods. ALWAYS try to reproduce in vainilla minecraft.
 * Okay, sorry. I tried it now with Vanilla 1.2.5, and again, the building was old. Pictures: Before converting and After converting. Is it a problem when there are mods in the 1.1 jar? Is maybe the world too big? It has 137 MB... --Galaxy_2Alex (Talk)

undefined It is not uncommon for a village which spawns next to or on top of a ravine to have numerous buildings with doors too high to use. You could also consider them to have ground too low for the houses.... (example, seed 5291744673974258690, village at 64,-224)(also, this is an awesome seed with a great spawn.)

undefined Sometimes, tall grass can spawn floating above ground.

undefined If you make wolves become aggressive, and then pause the game, they continue to attack you while in the pause menu, and can kill you while you are in this state.

undefined Caves will generate by carving air blocks out of the ground. However, there are two different "place block" calls -- one that notifies neighboring blocks, and one that does not. Caves appear to generate with the non-notify one. This can be observed in MC Gamer's UHC S6E5 from 8:53 to 9:39. Air blocks are carved out with the non-notify variant of place block, so gravel can be suspended over air with nothing supporting it just like a Vechs trap.

That gravel should have collapsed when the cave was carved.

Someone who did not know that vanilla MC can generate collapsing gravel -- like me -- would have dug and died there. Unfun.

a When upgrading a map, changes to the world generator will create strange occurrences in the world, such as walls of large cliffs next to oceans.

Example: http://img215.imageshack.us/img215/1117/glowstonebug.png Walking into the dark area generally causes the light to update (but not always), but logging out and back in reverts it. The same chunks seem to be effected. Putting torches in the area works as a band-aid however. DarkWolff 01:46, 5 April 2012 (UTC)

 * Yes, it is chunk aligned and yes the map was converted, though I extended the glowstone just pass the dark area in 1.2.1. I don't recall if I tried replacing blocks, but will try when I get home. I've mostly been putting down torches and removing them whenever there is a patch (been around since 1.2.1) to check if it was fixed. I've also seen similar bugs in other areas with lava, but never as bad as this. DarkWolff 15:23, 5 April 2012 (UTC)
 * Ok I tried replacing he glowstone and when I relog the area becomes dark again. Basically the glowstone will not light up the area in those chunks. DarkWolff 00:40, 6 April 2012 (UTC)

! New lighting system severely drains FPS since 1.2. This problem persists in 1.2.5. Lighting changes in-game caused by lava, redstone lamps, redstone repeaters, and/or pistons cause heavy FPS drops and/or stuttering on low- to mid-range computers. This problem didn't exist in any version prior to 1.2. It looks as though there is now a lot of excess load on clients to calculate lighting changes, whereas pre 1.2 Minecraft forced the server to deal with lighting calculations. This essentially makes the nether and busy piston/redstone contraptions unplayable as the FPS lag is extreme. d3fin3d

 * Unfortunately, even with 4GB of RAM allocated to java, and thus minecraft, this lighting memory decay issue causes me to place blocks twice. It is not a mouse problem, but an FPS issue.

I'm running 65 bit Windows 7 with 4GB of RAM, i3 with 2.27GHz, Intel HD Graphics, 64 bit Java, and the default value allocated to Java. Changing to 1024MB and 2048MB didn't affect it. Playing in vanilla doesn't fix it. I have found that barely tapping the mouse button will fix it about 75% of the time, but it is extremely inconvenient.--frogjg2003 02:05, 2 July 2012 (UTC)


 * Same here. Also offline mode. I have tested it with different mice. If redstone is near by, it always generates long right clicks, so that i place blocks twice, can't open/close doors and can't use switches.

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

! New lighting system allows phantom sky-lighting in large covered areas. Bug is easily reproducible. There is a community fix titled "LightOff" which addresses the issue.

! Sometimes when you remove/place a block the graphics will not update. This causes blocks you place to be invisible, blocks you remove to look like they are still there and doors/trapdoors you open to look like they are closed. This only happens in certain chunks.

aThis video quite clearly shows the problem, a graphical, pixel-thick transparent grid around blocks, grass blocks being most prevalent, and the torches have been affected as well. A high resolution texture pack makes this unbearable, but with a completely vanilla windows client and the default texture pack it is still painfully obvious that shouldn't be there. I noticed it after I installed java (64 bit) 7 update 5 after having minor problems with my client, but I tried java 6 update 33 (using in video), same results, I suspect the new versions may be the cause. --Greatwroth 09:58, 13 June 2012 (UTC)

I don't understand, the client hasn't updated recently (not to my knowledge at least) neither has my graphics drivers (which are working just fine in EVERYTHING else), I just can't seem to pinpoint the problem. --Greatwroth 23:12, 13 June 2012 (UTC)

Sound
Bugs !!Not sure if this qualifies as a bug, but I believe it does. OpenAL32.dll and OpenAL64.dll both had problems. If I tried to enable sound, the game would crash, and with certain mods (such as IndustrialCraft) the game would crash. None of these times it gave an error report. Currently the workaround I've found seems to be deleting the .dll files in %appdata%, forcing Minecraft to use the Windows default ones.


 * deleted both .dll files, can enable sound but still no sound plays. possibly no default .dll's for minecraft to refer to? -Kilo223


 * I also have the same problem. My sound and music are set at 0, and when I try to turn them on or up, my client crashes. I, however, do get an error report. It has been this way since I bought the game back in Beta 1.3, but only on my desktop. I can hear the sound fine with my laptop, though. I am running 32-bit windows vista. -Dlizard1397


 * I had this same problem on windows 7 64bit. To fix the problem I simply went into control panel, selected sound devices and disabled every driver that did not play a sound when tested. After that was done I had sound. The more precise directions are as follows: open control panel, select "Hardware and Sound," select "Sound." This will open up a new smaller window with your sound drivers. The first tab is playback and it will give you a list of drivers. Test all of them and disable the ones that do not play any sound. Restore any files you might have deleted trying to fix the program that was not broken then you should be good.

undefined Sound files aren't being downloaded to the resources folder resulting in a loss of sound. I find this a little weird since 1.2.4 was out I had perfect sound and after a few months of playing in 1.2.5 i completely lost sound.

Annoyances a! For some reason, even with my computer on full blast and sounds at 100%, I cannot hear a thing. This is lethal with Creepers around. I haven't done anything, but my Minecraft crashed lately, leaving me with absolutely nothing in my inventory, but everything in my chests were saved.
