Minecraft Wiki:Issues/Beta 1.9pre1

A pre-release for Beta 1.9 has been recently released by Jeb. This page is for reporting bugs on the pre-release of the game.

''' Use the Discussion page first before editing any onto this page. ''' Bugs can be confirmed by checking into the discussion page and make sure other people reply to your report and have the same problem. If you and other people are experiencing a supposed bug, it may be listed here but with a "(?)" label in front of it to state if the occurrence may not be a bug if you and the community are unsure or at unease.

= Bugs = This page is for new bugs found in Beta 1.9pre, any bugs found in 1.9 that exist in older versions will be deleted. Note: An increase in experience when jumping and the lack of repeated jumps while holding the jump button ARE NOT BUGS ''. Please stop reporting these.''

Biomes

 * A border into a Swamp Biome displays a harsh change in color with grass, tree, vine, and water unlike normal Biome borders. [[Image:2011-09-22_11.27.46.png|Image:2011-09-22 18.44.10.png|right|thumb|200px|A change into a Swamp Biome is not smooth.]]
 * Water color underground (even at level 5 Bedrock) is still affected if the cavern is beneath a Swamp Biome.

Blocks

 * Lava touching water may sometimes create a Sandstone block.

Crashing

 * For some players, creating a new map will stop the process and the game will say "Switching Level", and shortly after closes Minecraft.
 * For some players, generating new chunks in a pre-1.9 world will crash the game, leaving no saved data.

Creative mode

 * The Gold Nugget is unlabeled in the creative mode inventory, which is located to the right of the Ghast Tear.
 * Mycelium, Lily Pads and Nether Brick Stairs are not shown in the creative mode inventory.
 * (?) Lily Pads appear to show a light gray texture when viewed in your inventory.

Files

 * For new maps, the MB size in the world file under the Singleplayer menu will not change, it will stay at 0 MB. For existing worlds, the size in MB will not change when exploring new areas.

Gameplay

 * Pressing Shift twice quickly while walking forward will cause you to sprint which was said to be disabled.
 * Torches cannot be placed on top of Netherrack Fences.
 * Lily pads may be destroyed by the player and picked up, but cannot be placed. In the player's inventory they also appear to be gray instead of green.

Lighting

 * Occasionally, naturally spawned torches will not illuminate properly.
 * Glowstone does not self-illuminate properly; i.e. a block of Glowstone encased in glass appears nearly black.

Mobs

 * Snow Golems will not leave a trail of snow on Mycelium blocks. Snow Golems will leave snow trails only on trees in a Swamp Biome, no other tree.
 * (?) Snow Golems take no falling damage.
 * Snow Golems can be created underwater.
 * (?) Snow Golems will not melt/die when arriving/created in a warmer Biome (such as a Desert). Snow Golems were said to melt when in the presence of a warm Biome.  Snow Golems can be created and will not melt when made in the Nether, which should not be possible as water will evaporate when used in the Nether.
 * Snow Golems cannot be created mechanically (For example: A piston moves a Pumpkin block onto two blocks of snow yet the mob will not spawn).
 * Mobs seem far less able to jump, and are prone to getting stuck in one block deep holes in the ground.

Multiplayer Related

 * Shearing a Mooshroom results in a duplicate client-side Cow visible only to the shearer.
 * Blaze monster spawners will display a pig inside the block.

Memory/CPU General

 * Excessive lag on new or existing worlds, even if new chunks are not being created and all graphical settings are set to Fast/Off. The lag is much worse on single-core CPUs, possibly due to the threading of chunk saving/loading.
 * For some Windows users a possible fix for this lag (or a reduce in lag) is to set "javaw.exe" to High Priority in the Task Manager under the processes tab. Seeing how this method affects the smoothness of the game, this is confirmed to be a memory leak.
 * Another fix is to wait for the 1.9 release, as Jeb is fixing this.

Sound

 * Chests will not produce any sound when opening or closing.
 * Endermen, Snow Golems, Blazes, Magma Cubes and Silverfish do not produce any sounds.
 * (?) Villagers do not produce any sounds.
