Minecraft Wiki:Issues/Beta 1.8

This page's purpose is to list all the bugs players have come across in version 1.8. They pertain to the unmodified, unhacked game. Most of the single-player bugs also apply to multi-player.

Version history also contains newer bugs that may not be listed on this page at the moment. Refresh often as well, this page is changing a lot while we get things organized.

Bugs and feature requests can now be logged at Get Satisfaction: Mojang.

General Bugs
The following seem to affect Windows, Mac, Linux and Solaris, and both game modes. Unconfirmed / unproven bugs have a (?) next to them.

Gameplay

 * Holding down right-click will not place blocks continuously. It is uncertain whether this is intentional or a bug.
 * Holding down left click emptyhanded (punching) doesn't continually punch entities. It is uncertain whether this is intentional or a bug.
 * Middle-clicking (clicking the scroll-wheel button) no longer changes the selected item (in the bottom bar) to the block middle-clicked on.
 * Shift-clicking chests from the output of a crafting table does not work (When you have crafted a chest).
 * Items that are ejected from a crafting slot after closing it drop twice the number of icons. When the original items are picked up, the 'ghost' items are left behind. The items also duplicate in the inventory, but only allow one use. The 'ghost' items in the inventory can be removed by merging them with real items. The 'ghost' icons on the ground can be destroyed with fire.
 * Trying to place a vine in the Nether will cause the game to freeze. (The game quits most often in the nether, as well)
 * Exploring new chunks often causes severe lag. (note: quitting/reloading is a workaround.)
 * The "Brightness" setting in the video settings menu always resets to "Moody" once you close the game.

Lighting

 * Placing a torch underwater will leave light in that area even after the torch is destroyed by the water.
 * Bedrock worlds basically have zero light, even with the brightness meter on full. Strange particles also float in the air.
 * Powered Minecarts aren't having lighting applied in torchlight/fire/glowstone. Powered Minecart on the left
 * Paintings with a block directly above them will stay black. They are also dark and unsaturated, in general.
 * Corners of blocks visible next to new types of stair blocks appear darker than they should.
 * Glowstone recessed into a wall appears dark despite being a source of light itself (originally fixed by beta 1.6).
 * Chests placed in a world created before 1.8 can appear to be a black box.
 * Redstone repeaters' tops are not lit correctly at night.
 * Using F6 and F7 in the Nether causes it to get brighter and darker, as if it was in the overworld.
 * Entities appear as though they are in a dark area for some users
 * Sometimes signs will turn black.

Graphical

 * Missing "cracking" animation on chests when breaking them.
 * Storage Carts have the chest part in an odd location.
 * Glass panes do not properly line up with / attach to double slabs like they do other solid blocks.
 * When you place a halfblock on top of a glass pane, it causes odd rendering glitches on the top of the pane - but only when the pane is facing north/south (the flat sides, not the edges).
 * When you are immersed in lava, the bright red visibility is missing when you are deep underground. Instead, the visibility is similar to that of a dark cave.
 * Bobbing up and down in water causes the horizon to alternate between visible and absent. Most noticeable when swimming in large oceans.
 * Ice blocks clip with iron bars.
 * The armor bar obfuscates a bit of the bottom of the map (item).
 * When sprinting on wood, wool, or any block with different metadata textures, particle colors use the default texture (example: sprinting on red wool creates white particles).

Stability

 * The game tends to run out of memory more often than before.
 * Another crash seems related to changing the state of a furnace. Simply putting in smeltable items and fuel can crash the game(crash log: ). The same happens once the furnace reverts back to the state without the fire animation. This bug will also cause the "timer" of the furnace to become stuck at maximum fuel. Once the last item of a stack is transformed it will quickly lower to zero. (There is no visible change for the first 7 items in a stack, in case you use coal as fuel. Once the last item is transformed, the fire symbol will vanish very quickly.) So the timer might cause an overflow.
 * It appears that, once furnace-related crashes start occuring, other crashes unrelated to the state of furnaces will also start happening. Restoring the original minecraft.jar seems to fix the problem.
 * Sometimes, the game can crash when entering the "Video settings" menu.
 * Attempting to change the graphics from "Fast" to "Fancy" or vice versa in the Main menu causes the game to crash. Workaround is to change settings mid-game
 * Similarly, toggling the Advanced OpenGL setting will cause a "dirt screen" crash. The same workaround works too.

Mobs

 * Mobs that die in lava may drop XP orbs (difficult to verify). These build up over time due to them not despawning, and can cause lag, especially when players frequent an area on the surface where this happens underground.
 * Burnt chickens and cows do not drop cooked chicken/ cooked steak like pigs do, but drop their raw versions instead.
 * Cave spiders appear to be incapable of passing through web blocks, or spawning in them, instead ending up spawning in rooms adjacent to the spawner "nest" (maybe intentional).
 * Cave spiders get stuck in a ceilings 1x1 hole, as they can get in but appear to keep jumping in and out of the hole, but instead are actually stuck. They also can get stuck at the ceiling layer if they are outside of a cobweb.
 * Occasionally a spider when suffering damage will glow much more brightly than normal. Textured spiders with transparencies also display a glow, but this is continuous.
 * When an animal is in water, upon attack they simply stare at you, instead of fleeing.
 * When a wolf is in water its texture will become completely black (tested with a tamed wolf at night-time) and will stay black even once it has left the water. This can be fixed by making the wolf sit or reloading the world while the wolf is out of the water (in SMP reconnecting and in SSP clicking 'Save and quit to title' and reloading the world.
 * If an Enderman carries a Grass block, said blocks textures are incorrect(showing the side texture on the top), presumably since their carried blocks show the same as blocks in the inventory.
 * Since passive mobs no longer despawn, they will accumulate in water holes or caves.
 * Passive Mob spawning is bugged, mobs spawn in very specific places in large groups (7-12 mobs per group spawned, all of the same type). Killing those mobs will likely spawn mobs of the same type again.
 * Certain passive mobs will not spawn at all in some places. This can be seen in mountain biomes where only sheep will spawn. May be intentional to show distribution
 * Chickens rarely drop feathers.
 * Endermen will destroy player-placed blocks in the same fashion as every other block; randomly. This includes chests. Endermen can even pick up obsidian, TNT and bedrock. These blocks are lost forever when they are killed.

Weather

 * Rain always has the same intensity and volume, beginnings and ends are sudden. This bug also happens in 1.7 versions and before, but only in multiplayer.
 * Rain appears in places where it shouldn't be until the player moves closer to it (for example, through the ground or in a desert area).

Items/Blocks

 * Cacti may be invisible.
 * Using bonemeal on a mushroom to create a giant mushroom will cause the block under the mushroom to change to dirt, no matter what type of block the mushroom was initially placed on.
 * Bonemeal does not work on melon or pumpkin stems.
 * Giant mushrooms are not flammable (may be intentional).
 * Placing vines in nether causes a crash
 * Mossy and Cracked Stone Bricks drops smooth Stone Bricks when destroyed. When they are placed in the world by the player (with INVedit or similar programs) they appear as smooth Stone Bricks.
 * Brick and Stone Brick Stairs have a weird lighting bug if they placed next to walls.
 * Silverfish-spawning "block 97" stone doesn't drop anything (unknown if intentional).
 * Block 97 is broken much faster with fists than with any tool.
 * If a vine is close to a glass block and you are on the opposite side of the glass, you will not see the vine through the glass.
 * When you grow a giant mushroom in the Nether (maybe in real world too), the top blocks are sometimes invisibles... Can be fixed by add/remove a torch close to the invisible zone.
 * Place or remove a block directly near a mushroom will cause it to "depop" (as if you break it).
 * You can collect Tall Grass with Shears (may be intentional)

World Generation

 * In Ocean biomes there are occasionally cubic underwater pockets of air. These can form inside rock faces, on the ocean floor, or even in the middle of the water.
 * In NPC Villages, houses' doors can be generated buried by other blocks, even the gravel roads. Further, they can be placed significantly off the ground, so they're inaccessible.
 * In NPC Villages, gravel roads can fall into caves, the ocean, and go too quickly up a hill.
 * Villages can be generated in shallow water
 * Torches placed by the terrain generator (in NPC villages as well as in abandoned mineshafts) sometimes fail to light the surrounding area. Forcing a relight, e.g. by placing another torch (which can be removed afterwards), will solve the problem.
 * Ravines seem to generate after abandoned mineshafts, causing mis-placed blocks and inaccesible areas.(i.e. floating support beams, floating tracks, floating chests, etc.)
 * There is no snow in any worlds generated after the update.
 * In biomes, there is almost no middle ground between 'no trees for miles' and 'trees everywhere, for miles', making it difficult to gather wood for crafting when you have an unfortunate spawn point.
 * If a ravine is generated in (or next to) a swamp biome, it sometimes cuts through a body of water. In that case the water will not update and flow into the open space, leaving an area that looks like the border of a chunk error. If a block next to the water is updated it will flood a part of the ravine, thus creating a waterfall. (This bug existed in 1.7)
 * Torches generated in the stronghold rooms are sometimes not correctly aligned to their block. (An example of this can be seen in the Yogscast stronghold video.)


 * Ground is less likely to have an even coat of topsoil in mountainous regions.  (may be intentional)
 * NPC Villages may be suddenly cut-off and have missing walls which may be glitched and block movement. (An example of this can be seen on the Yogscast NPC Villages video).
 * Tall grass is also generated on non-grass blocks (dirt) . (Bug present since 1.7)

Control Bugs

 * The F8 mouse smoothing key does no longer work.

General Survival Bugs
The following seem to affect Survival mode on Windows, Mac, and Linux. Unconfirmed / unproven bugs have a (?) next to them

Gameplay
Above bug also can crash the game in Survival mode.
 * F6 used in Creative mode to fast forward the day/night cycle also works in Survival.
 * This may not be a bug.

Crafting

 * Major Item Duplication Bug: put an item into the crafting table's interface -> double tap E -> when the item ejects from the table and you pick it up automatically, move the item/stack in your inventory, another of that item appears singularly in your inventory. The singular item is infinite, the initial stack is not.


 * Also, items ejected from the crafting table produce extra bouncing icons (sprites?) that seem to adhere to the standard decay timer of dropped items. This may be tied to the duplication issue.


 * Works with crafted items and blocks, even dirt.


 * Workaround: Wait for the extra dropped items to decay and put the duplication item on top of an incomplete stack.

GUI

 * Cube-shaped blocks in the inventory no longer have shading applied to them. This may be intentional as they are the same as cubes in Creative, which in turn roughly emulates the inventory in Classic.

Food

 * When the player is in a boat, the food bar does not drain.
 * Mushroom Stew does not stack. This is not a glitch as mushroom stew is replaced with an empty bowl when eaten. When using a inventory hacker to stack mushroom stew, the stack becomes 1 empty bowl when eaten.

General Creative Bugs
The following seem to affect Creative mode on all operating systems. Unconfirmed / unproven bugs have a (?) next to them

Gameplay

 * A number of items/blocks are missing from the inventory menu (Water, Lava, Monster Spawner, Jack-o-Lantern, Snow, Tall Grass, Fern, Mossy Stone/Damaged Stone Brick and all the dyes expect for the Ink Sac)
 * You can break Bedrock, and falling into the void causes player death
 * There appears to be no limit to the height that can be flown up to.
 * After ascending to a certain y-value (about 107-109) during a rainstorm, you can no longer hear the rain.
 * It is possible to be lit on fire, although it does no damage (probably not a bug)
 * You can kill monsters from far and through walls.
 * You may drop and pick up blocks. This may be intentional, as it is the only way to test certain kinds of redstone creations that require items to activate a pressure plate.
 * If you pick items when your hotbar is full, it will go into your inventory which you can acces with a furnace, workbench, or chest. (maybe intentional)
 * Going with the above you cannot wear armor or 2x2 craft. (maybe intentional)

General Multiplayer Bugs
The following seem to affect CMP/SMP modes on Windows, Mac, and Linux. Unconfirmed / unproven bugs have a (?) next to them

General

 * Parrying doesn't work. (Parrying may not be included in the 1.8 update)
 * Player doesn't make hand movement animations when using entities. (Doors, Chests, etc.)
 * XP orbs dropped by player's death cause massive server lag. Since players die frequently on SMP servers and XP orbs don't seem to despawn, the lag is even worse. Twitter: jeb_ supposedly has fixed this. For release of an updated pre-release or the actual 1.8

Mobs

 * Endermen only attack you if you attack them first, they don't if you look at them and stop looking at them.
 * Mobs haven't a "critical hit" animation

Creative Single Player 1.8 (CSP) Windows
''Unconfirmed / unproven bugs have a (?) next to them. Observed on Windows OS, may exist on Mac OSX and Linux''

General

 * You can punch mobs from a very long distance. (May be intentional)
 * Items are dropped when harmed by explosions or environment (such as a cactus losing its lower trunk).
 * Items that are dropped can be picked up (though not always), and will accumulate if present in the active bar.
 * All maps are the same, a map centering at x=0, z=0,
 * You can fly into the void. (Probably intentional)

Blocks

 * TNT drops itself when hit and when taken will not fill an empty inventory space like other blocks.

Survival Single Player 1.8 (SSP) Windows
''Unconfirmed / unproven bugs have a (?) next to them. Observed on Windows OS, may exist on Mac OSX or Linux''

Lighting

 * The hand's lighting seems to randomly skip between normal and dark in first person.

Beds

 * Using a bed in survival will occasionally cause it to skip to sunset instead of sunrise.

Doors

 * (?) For some players, doors do make a sound when left clicked

Furnace
There is a patch for those chrashes on minecraft forums,http://www.minecraftforum.net/topic/615356-patch-furnace-crash/
 * Using a furnace (placing something in a furnace and when the fuel burns out) will crash the game and display 'Saving Chunks'. (doesn't affect all players and not all players that are effected are effected all the time)
 * when a furnace runs out of fuel, the game will sometimes crash.

Lava

 * (?) Swimming in lava causes the screen to become darker than it would before 1.8..

Mobs

 * Endermen make sounds identical to those of a Zombie. This is an intentional placeholder to prevent them from being silent until the resources folder is 'officially' downloaded upon the release of 1.8.
 * Squid do not drop experience points upon death.

Performance

 * FPS is fluctuating (seems to depend on the direction the player is looking at) and is much lower in average compared to 1.7. This may be caused by a very large number of experience orbs. Switching "Advanced OpenGL" on helps a lot, if supported.
 * Lag increases dramatically after death. This is because the player drops all their collected experience orbs after death, which may be thousands. (This is especially a problem on SMP servers, where people die quite frequently)
 * Very high numbers of entities upon world load. Even higher amounts if the player chooses to explore.

Other

 * Experience orbs never, or take much longer than expected to, disappear with time.

Survival Multiplayer 1.8 (SMP) Windows
''Unconfirmed / unproven bugs have a (?) next to them. Observed on Windows OS. May exist on Mac OSX or Linux''

Building
Frequency of occurrence: Every few blocks.
 * Stone blocks destroyed by a wooden pickaxe turn into Iron ore immediately after being destroyed. Stone blocks drop cobblestone before turning into Iron ore. If you destroy the Iron ore you will receive the drop. If Iron ore is left alone it will disappear after a few seconds.
 * Doors (that are placed by other players?) can be opened and closed, but do not play a sound effect, nor do they cause your arm to swing.

General

 * Servers may experience major lag issues (FPS 0 to 1) upon the death of a player who is carrying experience orbs. When the player dies, all of the player's orbs will be dropped. This can commonly cause the game to slow to such an extent it must be force quit and cause massive amounts of lag on SMP servers, making the map unplayable. It is possible to remove the orbs with MCEdit, making the map playable again.
 * Servers still running pre-1.8 maps may experience major lag.

Graphics

 * When it starts raining there are places where you can see the rain but not the bouncing particles and places where you can see the particles but not the rain. See here.
 * Connecting to a server that is in the middle of rain will cause rain to appear in all empty spaces, including in areas with a roof (I.E. player houses, caves, arches, etc.). If blocks are broken in areas with a roof, the space created by breaking the blocks will not have rain.

Mobs

 * Endermen are unresponsive and do not interact with the player.

Flying

 * If a player is flying and then is moved from Creative to Survival he/she will not be able to stop flying until moved back to Creative.
 * While swimming water may act weirdly

Server Crash Report

 * I've had this happen after a player teleported to me. Note I was getting "not enough RAM" warnings on startup of the software although I have 6GB. No mods, fresh download. Hosting with Hamachi.

[SEVERE] Unexpected exception java.lang.NullPointerException at oj.h_(SourceFile:111) at eh.e(SourceFile:1193) at net.minecraft.server.MinecraftServer.h(SourceFile:370) at net.minecraft.server.MinecraftServer.run(SourceFile:303) at ce.run(SourceFile:418)

Creative Multiplayer 1.8 (CMP) Windows
''Unconfirmed / unproven bugs have a (?) next to them. Observed on Windows OS. May exist on Mac OSX or Linux''


 * You cannot hear your own block breaking sounds
 * Blocks disappear only after the removal was confirmed by the server (annoying when server ping is 200 ms)
 * When players put maps into their inventory and look at them, the maps may have the same id (map_0) and the client will disconnect with an "Internal server error" message
 * Falling to death (with /gamemode playername 0) can disconnect a player with an "Internal server error" message

Creative Singleplayer 1.8 (CSP) Mac OSX
''Unconfirmed / unproven bugs have a (?) next to them. Observed on Mac OSX. May exist on Windows or Linux.''

General

 * If you break a block with redstone on it the redstone will drop and mess up your inventory if picked up.
 * You are not supposed to eat while playing Creative, however Golden Apples can be eaten like normal. (This is a joke, not a bug)

Survival Singleplayer 1.8 (SSP) Mac OSX
''Unconfirmed / unproven bugs have a (?) next to them. Observed on Mac OSX. May exist on Windows or Linux.''

Graphics

 * Trying to change visual settings in the main menu will provide an error message and a black screen.
 * All mobs can have lighting issues.
 * Steps placed perpendicular to blocks create an odd shadow on the block
 * If you walk into or near to a wall that is next to iron bars or glass panes your view slips into the wall and goes black
 * If you mine, the blocks get a brownish tint, and when you place a torch in the brownish tint, the sides mess up
 * Ghasts don't glow like they are supposed to. Possibly due to new lighting engine. (More than likely exists on all OSes.)

Smelting

 * When a furnace starts or stops smelting, the "saving chunks" crash occurs.
 * Sticks act as infinite fuel (?)

Minecart

 * There are some instances of floating minecart tracks in strongholds.

Terrain Generation

 * Grass blocks appear in the sky.
 * Floating pumpkins may spawn.
 * Mobs may become trapped in a tree's leaves when they spawn.

Building

 * Iron Bars, Fences, and some other items can now be placed on top of tall grass.

Beds

 * Punching while in bed before the sun rises will break the bed. As a result of this, the player gets ejected from the bed and has the ability to noclip through the ceiling and walls around them. They are still affected by block ejection, forcing the player out of the blocks it moves into, and still take suffocation damage.
 * The FOV is too close to your head when you're falling asleep, causing you to see inside your own head.

Survival Multiplayer 1.8 (SMP) Mac OSX
''Unconfirmed / unproven bugs have a (?) next to them. Observed on Mac OSX. May exist on Windows or Linux.''

Creative Singleplayer 1.8 (CSP) Linux
''Unconfirmed / unproven bugs have a (?) next to them. Observed on Linux. May exist on Windows or Mac OSX.''

Survival Singleplayer 1.8 (SSP) Linux
''Unconfirmed / unproven bugs have a (?) next to them. Observed on Linux. May exist on Windows or Mac OSX.''


 * On linux, when minecraft freezes, it may keep capturing the mouse, making it difficult to do anything. Depending on the desktop environment, this can be fixed by opening a TTY with ctrl+alt+f2, then logging in, and entering: "export DISPLAY=:0;nohup metacity --replace & 0". And then returning to the X-Server (usually tty7 or 8, ctrl+alt+f7 or f8 respectively)

Survival Multiplayer 1.8 (SMP) Linux
''Unconfirmed / unproven bugs have a (?) next to them. Observed on Linux. May exist on Windows or Mac OSX.''

Other OS Bugs
''Unconfirmed / unproven bug have a (?) next to them. Reserved for bugs related to operating systems other than Windows, Linux and OSX.''
