Minecraft Wiki:Issues/Beta 1.9pre5

The fifth pre-release for Beta 1.9 has been recently released by Jeb.

''' Use the Discussion page first before adding any bugs 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.

Bug Labels:


 * [X] = Minor bugs.
 * [!] = Major bugs.
 * [!!] = Bugs that can crash Minecraft or a server.
 * [?] = Possible bugs/features that you and the community (on the discussion page) are unsure about.
 *  [U]  = Bugs that Jeb tested but was unable to reproduce.
 * [A] = Annoyances.
 *  [F]  = Bugs that have been fixed in the next update.

Blocks

 * [X] Tall grass can be generated on dirt and gravel in NPC villages.
 * [?] When a water block is placed with empty space underneath, a column of source block is created under the water block. (Maybe an intended feature? Might help keep oceans from having random holes where land used to be.)
 * [!] Quitting to title menu while standing on a pressure plate will activate it forever. It must be rebuilt in order to make it usable again, this goes for items on wooden pressure plates too. [Verified]
 * [?] Flowers can spawn upon sand blocks but cannot be placed upon sand blocks by the player.(Only seen with yellow flowers)
 * [?] Patches of swamp water can be seen in the middle of a lake with no swamp land around it.
 * [?] Arrows do not get stuck in lilly-pads.
 * [?] Snow Golems still attack mobs in creative mode in which are neutral.
 * [?] Right clicking on a water block with a glass bottle while having a full inventory will eject a water bottle
 * [X] Lilly pads do not show up in creative Lilly-pads do appear in creative, are you using a texture pack without the lilly-pad texture? They dont appere in the creative selection screen
 * [X] Enchantment Tables break with a single punch and are destroyed permanently, although they can be mined with a pickaxe.
 * [?] It is possible for a lilly-pad to spawn underground and on flowing water. Example:
 * [?] Chests don't make sound when opened or closed. Intentional. Was fixed in an earlier release (bad idea!) - FYI, the sfx were changed to "chest_open" instead of "door_open", and the sound effects aren't uploaded to S3 yet. /jeb
 * [?] Chests connect with each other when placed three in a row, with a graphical overlap. When opened, they show the inventory of 2 like normal.
 * [X] This one is hard to explain with out pictures. Normally you need a water block next to a Sugar Cane for it to be able to place, well in water if there's a water block next to it (just like you would normally place water on the surface) you can place the Sugar Cane.
 * [X] If you place a Sugar Cane next to some water and than put any block around that Sugar Cane to block the water it will still stay up with out any water. If you place another Sugar Cane on top of it, it will break, not sure if it breaks if it grows or if another block is placed on it. It has always been like this. Sugar Cane can stay in place with no water source, but will shrink back down to one cane high and the whole cane will break if it is touched in anyway.
 * [?] If you leave a creative world, then rejoin it, any empty inventory spaces reset to the default blocks. Not a bug, has always happened this way. Simply replace the items with the ones you had before from the infinite inventory.
 * [?] Eyes of ender will sometimes go to areas without an ender portal. Did you create the world pre 1.9pre 3 or 4
 * [?] Shrooms pop out, when something is placed next to them. (If the light level is too high the shrooms will pop out if there is a block update next to them)
 * [X] Dead bushes don't get placed in creative mode.
 * [X] Signs may be placed on one another, connected as if placed on a normal block. Always been like this, likely intended.
 * [?] Signs now have similar properties to doors, meaning they drop when the block they are on top of breaks as well. Always been like this, likely intended.
 * [X] Lily pads can now be placed by right clicking on the side of a block 1 space above water, though when placed on vines using this method, the vines disappear. Same happens with mushrooms, though they are just broken. May also work with other blocks, haven't tested this yet
 * [X] The Bug where trees growing on the edge of a biome can have their leaf colors divided across the line is back.
 * [X] When placing a halfblock of sandstone, and another one under it, then another one over all of them, the blocks combine into 1 sandstone block at the bottom.
 * [?] Pistons can be used to generate an infinite supply of sand and gravel blocks.
 * [X] Cant place a torch under a stair block
 * [X] Glass pane don't connect to stairs:
 * [X] Pistons can be powered by blocks that are not directly connected to them (diagonally above or 2 blocks above) leading to changes in those blocks not updating the piston, but when the piston is updated it will take those blocks into account.
 * [X] Save and Quit while water and/or lava is flowing downwards from a high source block can lead to weird freezes in state upon reloading the world (suspended blocks of fluid).

Crashing

 * [?] Some users report F11 causing a blackscreen crash. I have experienced this before usually fixed with pressing F11 fullscreen glitch possibly happens when in game full screen when to tab out users press F11 this can be avoided by alt + tab to tab out like that - alizter1234
 * [!!] When placing Enchantment Table, game crashes. (SMP tested only) The game does not crash when placing the Enchantment Table (Has been tested in both SMP and on MP)
 * [!!] Creating a world with the name being a "." (period) crashes your Minecraft client. I have tried to recreate this scenario in Hardcore, Survival, and Creative modes, but to date it I have not been able to recreate it.
 * [!!] Maximising the window and moving it to another monitor before pressing 'E' or right clicking an interface after starting the game will result in the game crashing with the "Saving Chunks" screen upon pressing 'E' or right clicking any interface in Mac OS X.
 * [!!] After playing for a few hours an error will occur causing the "Saving Chunks/Out of Memory" error
 * [!!] Game (clients and ?servers?) cannot tell when it is in distress / running out of memory / processing due to an entity (Mobs or blocks on the ground) overload. Propose that when memory/processing usage is approaching critical levels, the game should take much more aggressive management of entity removal.  This can be achieved in vanilla ssp/?smp? through standing next to a mob spawner dropping mobs into a trap outside the check range but mobs remain inside the "mob reborn" range (this may have been a bug of the above memory leak, the game crashed and I was not able to restart it).  This can be achieved artificially with MCEdit with a 2x2 chunk room 10-20 blocks high and replacing the air with torches or similar.  Entity overload on SMP creative through the use of scripts mass-dropping blocks (before the ability compress blocks into a single unit) is/was a well known and often abused griefing tactic.

Files
Installing Java 7 will fix the problem.
 * [!!] The fifth pre-release and any other pre-releases will crash when making a new world in singleplayer, leaving a notepad file on the desktop.
 * [X] On servers if the ops.txt file is missing the message generated states "Failed to load ip ban list" obviously copied from banned-ips.txt message and not modified.

Gameplay

 * [?] There is no apparent way to turn off f10 causing the game to be unplayable without a reinstall. It also seems to be on no matter what save I go into.
 * [X] The terrain generator doesn't smooth biome transitions.
 * [X] Spiders will still attack you in Creative mode.
 * [X] In SMP, the server won't load the End or Nether; therefore making both worlds not generate (the End is just the 5x5 obsidian platform you spawn on).
 * You must dig up from the obsidian you spawn on, you only have to go up 5 blocks
 * [X] When entering The End, it is possible that you will spawn off the generated blocks and be placed on a 5x5 block of obsidian. If played on a mode other than creative, it would be difficult to make a path to the rest of the map. (gravel/sand?)
 * Same as above
 * [X] You can't hold down the left mouse button to continuously attack any more. Has been since 1.8, intentional.
 * [X] You can't hold down the left mouse button to to break a minecart any more. Same as above.
 * [X] Redstone does not detect when redstone powered items are adjacent and direct power to them while it does detect repeaters.
 * [X] Noteblocks do not receive power from adjacent blocks that are powered by redstone, while everything else does (when a noteblock receives power from a stone block and the stone block is the one receiving redstone power).
 * [X] Noteblocks do not receive power when powered directly by a repeater that's powered directly by a stone block that receives power from a redstone line.
 * [X] Noteblocks do not receive power from a redstone torch sitting on the side of a stone block.
 * [X] Sometimes after saving while flying, it becomes as your walking/ground level enabling sneak and disabling fly. Effectively trapping the player at a fixed level.
 * [X] If you exit the game (or or the game crashes) while in a minecart you will start next time buried up to the waist in the ground. If there's lava one block down you'll burn. If you exited the game in a crash often the minecart is duplicated.
 * [X] If you exit the game (or or the game crashes) while in a boat you will start next time on the sea bed with the boat zooming away from you.
 * [?] While using a bed you will always be interrupted by a hostile mob. (even when the bed is well within a mushroom biome where no hostile can spawn) It seems the buffer distance between you and mobs has been increased to 3? - Are you in a house with double doors? Double doors allow mobs to wake you up unless it is redstone locked.
 * [?] Sugar Cane seems to grow at a reduced rate.
 * [?] Seems that the rate which one becomes hungry is increased in Survival Mode, unsure if this is a bug or a feature.
 * [?] Endermen will attack you in Creative mode if they bump into a wall and you are near them.
 * [?] When logging on with a random username and password you can play minecraft singleplayer for free. (offline) -- True, but you must have offline (.minecraft) files, then you can log in with a random username. While an offline server would work with this method, an online server doesn't.
 * [?] Efficiency enchanted picks (tested with Efficiency 4 diamond pick) have little effect on reducing Obsidian mine time. Not sure if intended. Eff. IV should take 40% of mining time - 0.6 x 15s = 9s to mine obsidian.  Not tested.
 * In third person view (f5) pressing the "U" button will cause the camera viewpoint to move through the character and into the ground, instantaneously revealing all subterranean caves and objects. It is possible to navigate this view with the mouse and the "U" and "O" buttons, spotting ores, diamonds, mines, monster spawners, chests, and strongholds easily.  It is also possible to safely dig straight down using this x-ray vision.  Classified as a major glitch because such an easy exploit removes the exploratory aspects of the game, as well as the #1 rule of minecraft, "don't dig down." Jeb has stated on his twitter that the F6 Camera Controls are debug features that he accidentally left in the pre-release.
 * The terrain generator still doesn't generate beaches. It's not made to.
 * Can't switch Gamemodes on a server! No longer a bug, It's proven that switching game modes in servers work.
 * Shooting arrows in creative still depletes the stack (move if needed) This isn't a bug. It might be something that you don't like, but it's not a bug.
 * Brewing any ingredient with a water bottle always creates a Mundane Potion that cannot be brewed with other ingredients. This is not true, you need to use Nether Wart to create an Awkward base! -- I've tested it myself, potions are fine!
 * If your world was a creative world and you change it to survival, You can fly in survival mode with clicking space twice This is not a bug. There is no way built into Minecraft to switch game modes on an existing map. 1.9 prerelease 5 added a new abilities section to the level.dat, you need to use your NBT editor to turn off flight there in that section.
 * In creative, if you move the camera angles in any way (Pressing "N" "M" "Y" "U" "O" or "H"), you can't control your altitude when pressing the space bar or shift. This could be an anti-ghosting issue with your keyboard. It is not because I tried it with both a wired and wireless keyboard. Jeb has stated on his twitter that the F6 Camera Controls are debug features that he accidentally left in the pre-release.
 * Singleplayer, changed difficulty from normal to peaceful. Saw hostile mobs disappear and then I got attacked by one of those magma things, not sure if it spawned or if it was already there. It was already there and they don't despawn when changing difficulty, just like slimes, notch and jeb_ are well aware of this.
 * If you push F6 and move, if you are on your first item slot, you will move the fastest in either direction, however when moving from the first slot to the second slot, this decreases your movement speed a little, gradually decreasing your speed from the 2nd inventory slot to the 4th inventory slot. At the 5th inventory slot, you are incapable of moving. When moving from the 6th inventory slot to the 9th, it is the same as 1-4 except your directional movement is inverted.  This might only work until you crouch in F6 though.  If you move and scroll at the same time, you can see what happens Jeb has stated on his twitter that the F6 Camera Controls are debug features that he accidentally left in the pre-release.
 * The terrain generator still places Lava-lakes under Water. Not a bug.
 * You cannot left-click + hold to destroy blocks when in 3rd person view. This has been proven to be false, you can hold + destroy blocks in 3rd person view, front and back view.
 * [X] Water on top of fence posts can cause entities to hop in place if they move in any direction against a wall 1 block or more higher. This does not happen at all at the .5 minimal height for collision next to water on a fence post.
 * [X] Redstone does not try to connect to pistons
 * [!] Its stupid that ender pearls dont work in creative mode, it would be a quick way to travel around without getting fall damage That's not a bug and it's unhelpful to the page to post this sort of stuff.
 * [?] When you're in a snow Biome in Beta 1.9 pre5, if you make a fountain of Water and wait for it to freeze, you can take it with a Bucket, and the the next flowing water will turn into Ice.
 * [?] Mushroom Soup does not stack.

Graphical
^^''That is probably partly intentional, as "muck" is gross and gets everywhere. It would be kind of funny if the "muck" follows a bit in footsteps as you walk away :D'' ^^That sounds intentional, as when you are in bed or on fire etc it shows in the inventory screen as well.
 * [X] Activate F3 and open Creative Inventory. If you scroll down the background of the CPU-Time-Usage-Table (right bottom) disappears. Seems to happen if you see the "Golden Apple" with its graphical effects in the Inventory. //Update: This happens with every animated item in your inventory.
 * [X] Swamps have a horrible transition from any biome to a swamp biome leaving some nasty looking colors. Example:
 * [X] Glass panels are still flickering in 1.9 pre 5
 * [X] Due to the new camera positioning keys, switching keys (such as I for inventory, instead of E) causes "unintended" camera panning from the player.
 * [X] If you eat zombie meat and get infected then switch to third person and facing the character the infected animation doesn't play. Tested with fancy graphics and the default texture pack.
 * [X] Swimming/sailing in the ocean causes the horizon to flicker obnoxiously (since 1.8)
 * [X] The wheel texture is flipped upside down on one side of Minecarts.
 * [X] When you die, the player model in the inventory screen also appears dead, blocking some parts of the inventory screen/slots.
 * [X] While you're in bed, the experience level number doesn't fade out.
 * [X] When underwater with the camera position changed, it resizes the blue square filter you get when being underwater.
 * [X] After pressing f6, if you hit left shift to crouch, it inverts your movement controls.
 * [X] Water and lava drips under blocks where it probably shouldn't such as glass, signs and ladders
 * [X] If you are with a map in you hands and look directly into a entity, the map will become white. Proof: http://imgur.com/5F0Wq

Lighting

 * [X] Redstone Repeaters placed between two full blocks are dark when placed along Z axis. They are properly lit when placed along X axis.
 * [X] Black and white flickering on all mobs and the player arm when playing Minecraft on Windows XP. Has occurred since 1.8 // cannot reproduce.
 * [X] Black an white flickering on chests and all placeable objects on Minecraft Windows 7. Occurred since 1.8 // cannot reproduce.
 * [X] This lighting bug is better explained by a short, voiceless video here [Skip to 1:20 for the bug; earlier shows how to create].
 * [X] Sometimes overhangs create pitch black shadows, as shown here . However, when one gets closer to the cliff, the lighting is updated and the pitch black shadow disappears (as shown here ).
 * [X] If the block adjacent to a water source has a lighting issue, the bubble particles will become black.
 * [X] Glowstone behind glass is odd, the light shines through but the glowstone itself is almost black. Example:
 * [X] Chests and signs are often black or very dark even when in a well lit location

Maps

 * [!] When you are flying on ice, you will see the sides of the chunks (Confirmed for versions 1.6, 1.7.3, 1.8.1, and 1.9pre5)


 * [!] Created a map prior to 1.9pre5. After getting 1.9pre5, every new map made is an exact duplicate of the first one regardless of where it's made. Check and make sure you're not holding down shift when crafting the Map; this will always create a duplicate of "map_0"

Mobs
''Correction: you can see endermen and spiders far away in fog. This is completely intentional.''
 * [X] Spiders, endermen and silverfish will still try to attack you even if you have not provoked them in creative mode (other hostile mobs do not ).
 * [X] Squids will be facing up, and motionless (not including the squid arms animation) until approached Intentional
 * [?] Also, other mobs do not disturb squids
 * [X] When a chicken looks at the player it moves its head down instead of up.
 * [X] Hostile mobs can hit the player from a further distance (IE a creeper explosion can be considered point-blank when 4 blocks away) been around since 1.9Pre4
 * [X] You can see see mobs far away in fog, though they are white.(Possibly intentional, since similar effect is seen IRL)
 * [X] In a dark area, creepers and skeletons don't attack you.
 * [A] All (non aquatic) passive mobs make a bee-line for the sea. After a short while the land will clear of livestock which can be found floating offshore or trapped in ponds and pits. Includes chickens, cows, pigs, sheep & mooshroom cows.
 * [A] Passive mobs constantly bounce when next to fences even though they cannot get over.
 * [!] Mooshroom spawn too much in some area (see http://tof.canardpc.com/view/993ab614-4193-4b24-9d04-fcadd5c3f517.jpg). More than 29000 was removed with the help of MCEdit. The mooshrooms spawned back after several minutes.
 * [X] Sheering baby Mooshrooms yields a full grown adult cow rather than a baby cow. Possible exploit to gather beef faster from breeding by bi-passing the time spent to age.
 * [?][A] Slimes and Magma Cubes are voiding several spawning algorithm rules. Such things as spawning on top of blocks labeled in the game as non-spawnable (glass, half steps, stairs, etc); spawning inside of translucent blocks next to air blocks, such as spawning inside of a piston block; spawning inside 1x1 block spaces that contain translucent blocks such as redstone, repeaters or torches.
 * [?] Ghast hit box (and collision check when spawning) are set approximately one block too low.
 * [A] Slimes and Magma Cubes do not despawn when setting to peaceful despite being hostile mobs at all sizes. This is indeed a "feature" but it was also not as intended when originally coded.  The original intent was to allow the smallest version of them to spawn but remove the rest since the smallest ones do no damage, just annoy.  This clearly is not how they have been behaving all these months.
 * [X] Chicken clips through gravel block and asphyxiate while following the player with wheat.
 * [?] Enderdragon will spawn in normal world.(A bug or a lie?) Uh there is a mod to make they spawn anywhere with a golden sword, and it is usually used for demonstration purpose.

Multiplayer Related

 * [!] Return Ender Portal
 * [!] No Ender Map other than Spawn platform. (After exstensive testing... Might of just spawned Far off the island.....) -Flamespinner
 * [?] End Portal spawns you 1500 coords away or so from the floating island in the end.
 * [!] Cant switch gamemodes If you scroll up, the same "bug" has been resolved already (under "Gameplay").
 * [X] When exiting a minecart after riding it, the player floats and can clip into blocks. This condition only disappears when restarting the Minecraft client.
 * [X] When an arrow is shot at a block, the shot arrow floats to the top of the block. It does not stay at the position it was shot at.
 * [!] Nether Portals : Same bug as portal to The End (Portal is created above a huge lava lake, land is far away)
 * [A] Servers could use join/quit DDOS/flood protection through queueing, or at least the ability to limit/combine/reduce player announcements.
 * [!] Client-side world holes are still a frequent occurrence in multiplayer games.

Memory/CPU General

 * [X] The Macintosh version uses 32-bit Java, even on 64-bit computers (This is because the launcher specifies 32-bit java, but there is a fix.)
 * Same here, on Windows 7 64bit, unless you use a batch file, or shortcut:
 * "C:\Program Files\Java\jre7\bin\javaw.exe" -jar "full path to minecraft.exe"

Sound
There is not yet any bugs for sound.

Weather

 * [X] Sometimes a thunderstorm can start but it will not rain until near the end of the storm. Mobs spawn normally.
 * [A] Weather sounds/looks the same regardless of weather severity. Would be nice to be able to distinguish audio/visually between an overcast day, a light drizzle and "Get the **** out of this!" weather.  Thundersnows and Desert Lightning.

Lava

 * [?] You cannot take lava with a bucket in creative. When you try, the lava doesn't appear in the bucket. < Not a bug. You can spawn all items, so there is no need to collect the lava. The empty bucket is solely for removing liquids.
 * [X] When you are in lava, you can see through it.
 * I'm pretty sure this is intentional, and not a bug.


 * [X] If you eat golden apples while in lava in the nether, then come out of the lava, you will instantly die, even though the golden apples kept you alive.
 * This is actually another bug entirely. Entities accumulate damage while in lava then receive all of it at once upon exiting the lava.  Same as dropping a minecart a bunch of times from a great height without a passenger then putting an entity into it and sending it onto land with a dead end track.


 * [?] While in the Nether, I fell into the lava. I paused the game (with esc) but after a few seconds, the entire screen went completely red and the game froze. I had to end the process to get rid of it. (If you want to recreate my scenario for testing purposes, I was wearing full Iron armor at the time, if that matters.)

Water

 * [!] Water falling directly onto rails/redstone/regular torches from above will destroy that item completely. Water flowing onto such a square from the side causes the item to become a drop.
 * "'This is an intended feature; redstone circuits are destroyed by water.'"
 * be thankful that it turns into a drop instead of disappearing like older versions.


 * [!] if you have a column of water running down a wall and you block the hole, the water below it keeps flowing, it's like all the water becomes source blocks. //Confirmed, water placed above air will turn all blocks below into source blocks. This makes it impossible to have 1x1 flows of water because the source blocks will leak in all directions.
 * [A] Fluids such as water can alter other fluids to change their angle; however the angle of the water can alter whether or not an entity can jump out of the water. (Further explanation: Prior to 1.6 this feature didn't affect the way the water reacted with entities.  Current tests to exploit the angles of waters in all 4 directions when water was applied to corners or head on to shift the angle caused varied results.  For instance, it is impossible to jump out of a source block onto any other source blocks 1 block higher.  Using flowing water yielded a rather varied slew of results.  With just water straight ahead in the direction being tested, only West was able to hop out into the source block.  With water applied to the corners of a flowing stream to lift it up, 2 directions could hop out onto a dry block just fine while the other two could not.  All tests were done on the player, but I noticed these problems several months ago on a mob machine and did a slew of tests using mobs to gather the same odd results.)

Biomes/Dimensions
This is not a bug, as return portals have not yet been implemented
 * [X] There is no return portal from the End


 * [!] Mushroom Biomes are way to rare to find legitly This is an intended feature, as mushroom biomes are very valuable
