Bugs
Bug Labels: Major bugs will be labeled with [!] before it. Bugs that can crash Minecraft or a server will be labeled with [!!] before it. Minor bugs reports will be labeled with [X] before it. Possible bugs/features that you and the community (on the discussion page) are unsure about will be labeled with [?] before on this page.
Biomes
- [X] Sky worlds generating under y:60
- [!] Nether portals spawn in air(?)
- This occurs over large bodies of water/lava and is NOT considered a bug, it is intentional due to the addition of vast oceans, if this is not what you are talking about please include a screenshot.
- Old worlds existing from Beta 1.8.1 and below might have their biomes changed if updated to ANY of the 1.9 pre-releases. For example: A Forest Biome with a lot of trees and a surrounding body of water may might be converted to a Swamp Biome. This leads to ugly rendering and shading of the ground, and the tree's leaves.
Blocks
- [X] Placing a cake on a pressure plate table causes the cake to float a block above the pressure plate.
- [X] Ferns don't spawn.
Crashing
- [!!] In either creative or survival mode, while working on an Enchantment Table, by Shift-Clicking on an object in your inventory, the "Saving-Chunks" bug occurs.
- [!] Some clients (potentially those running on 64-bit JVMs) crash when attempting to generate a world or switch to that world, leaving only an empty folder with the world name in .minecraft/worlds
- [!] Sometimes, when switching from and to fullscreen (F11) the game freezes.
- [!] Shortly after returning to the Overworld from the Nether, whether by Portal or by death and respawn, if you attempt to approach the portal the game will crash. Seems to happen once you are close enough to hear the portal sound effects.
Creative mode
- [?]When ever moving the mouse over the enchanting table in the gui it says "Unnamed".
It might also do this in survival and hardcore mode.
Files
Gameplay
- [?] It is possible to consume multiple water (potions (?)) by rapidly switching active items. [1]
- [!] If you swim in lava while under the effects of a fire resistance potion, it appears that the vertical downward distance you swim/fall during this is applied as fall damage when you get out of the lava (or perhaps when you stand on a block IN the lava) - this typically kills you. [2]
- [!] In SMP, switching a player, including yourself, from creative mode to survival mode while flying will apply momentum built up from flying as falling damage.
- [?] When eating a single porkchop, more than one porkchop is used from the inventory.
Graphical
Screenshot of experience bar bug.
- [X] When you select a glowing item, it can turn the hot bar white on certain video cards.
- The hot bar turning white is a bug on many things, including pointing your cross-hairs onto a mob in the nether in the PR2.
- Can you specify the video card in your computer and supply a screenshot?
- [X] Sometimes the wood block texture will remain even though block has been destroyed
- [X] The experience bar in the gui shows up on the side of the screen as well, in SSP only. Persists after quitting and reloading.
Lighting
- [X] The cut into Stone Brick Stairs, Nether Brick Stairs, and Brick Stairs is not lightning properly. [3]
- [X] Wooden stairs let inside light out through them.
- [X] Lighting in the Nether isn't working properly
Mobs
- [X] Adult Chickens will spawn from thrown eggs instead of chicks.
- [X] Baby Mooshrooms do not have visible mushrooms on their back but are able to be sheared.
- [X] in SMP breeding animals doesn't make babies.
- [X] Baby sheep are always white, no matter the color of the parents.
- [!] Animals sometimes don't follow the player holding wheat
- [X] Baby Mooshrooms will turn into adult cows when sheared.
- [!] Snow Golems are invisible.
- [?] The Endermen do not spawn in an area where even 1 piece is altered.
Multiplayer Related
- [!] When you shut down a server, it always loses data. save-all does nothing. Additionally some chunks will not save the changes. When you leave and then return the area will be back to it's original state. (?)
- When a server is closed certain chunks do not save changes, restarting achieves nothing, appears to be the same chunks everytime that have problems, modifiying the chunks sing MCedit also achieves nothing - keeps reverting to a much earlier save.
- [!] Sommetimes when playing on server and the client disconnects, the server thinks that the player is still connected and does not allow the client to connect.
- [X] The server doesn't tell clients that some animals are children or parents:
- Parents and child animals can visually be put in love mode but they won't breed.
- Players get confused why animals don't follow them because they can't see that it are parent or child animals.
- [X] Critical hits no longer work on SMP. Additionally, The Critical Hit graphic only occurs when inside a minecart and punching it.
- [!] Enchanting seems to be only client side:
- Visuals indicate that the enchanting worked until the client notices that the item is not enchanted.
- The experience loss happens also only at the client side.
- Reconnecting to the server resets experience and item to the state before the enchantment.
Memory/CPU General
- [?] Increased CPU usage in general, and a possible memory leak when memory usage exceeds 1.5GB
Sound
- [X] Rain does not maintain sound. Under only a few circumstances will rain be heard, and once out of range of the sound, it will not come back.
Weather
- [!] Torches, rails, saplings, wheat and other nonsolid blocks are 'overridden' when snowfall tries to place snow on the same tile. This deletes the blocks completely.
