Minecraft Wiki:Issues/Beta 1.9pre6

The sixth 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. Please specify if the bug is in singleplayer, multiplayer, or both.

Organization
'There is no need to place bullet points before issue labels. Use bullet points only for comments. Be sure to leave a single totally blank line before each new issue (but not before comments), unless the issue appears directly beneath a header.'

Please ensure that the bug is tested on a 'vanilla', installation of 1.9pre6 with NO MODS installed

Please specify whether the bug was found on SSP, SMP or Creative and if it is repeatable on other modes.

Please mark your issue with one of these issue labels: (listed from highest priority to lowest)
 * !! = Critical bug that can crash a Minecraft client or server.
 * ! = Major bug. Use this tag sparingly; if there is consensus your bug is not major, it will be downgraded.
 * a! = Major annoyance. Think very carefully before flagging an annoyance as major.  Is it really more important than most minor bugs?  Use this tag sparingly; if there is consensus your annoyance is not major, it will be downgraded.
 * x = Minor bug.
 * a = Annoyance.
 * ? = Potential issue that you are unsure of or that the community (on the discussion page) believes requires further vetting. Note: do not use this label to indicate this-is-not-a-bug; instead, replace the issue's current label with [A] or [A!].  Furthermore, it is inappropriate to use this to flag something you disagree with; instead, express your opinion in a comment. When you apply this label to an issue, place it after the issue's existing labels; do not remove those labels.

Labels for indicating that an issue happens only in a particular game mode: (These labels cannot stand alone; you must use them in addition to, not instead of, the ones listed above.)
 * sp = Single-player.
 * mp = Multiplayer.
 * su = Survival mode.
 * cr = Creative mode.

Labels for indicating that an issue is restricted to a particular OS:
 * = Mac OS =  
 * = Windows =  
 * = Linux =  

Labels that Jeb uses:
 * f = Bugs that have been fixed in the next update.
 * s = Bugs that will be skipped/ignored for now.
 * u = Bugs that Jeb tested but was unable to reproduce. Append this tag to the end of existing issue labels, instead of replacing them.

To produce these labels, use the following code:  c where c is the code of the label you wish to use. (e.g., a for annoyances, etc.)

The default issue type is minor bug; you can produce this label with the shorthand  undefined .

''Be sure to sort issues by category, type, and priority: redstone issues go in the Redstone section, etc.; bugs go in the Bugs subsection, with major bugs listed before minor bugs, annoyances in the Annoyances subsection, with major ones before minor ones, and issues that Jeb has marked as fixed or skipped are moved to the Fixed/Skipped section. Issues that Jeb cannot reproduce, however, are to remain in their original place.''

Please sign all issue reports and comments by typing   (three tildes; tilde may be found above  on US keyboards).

'Finally, please do not spontaneously delete an issue report or comment, unless it is patent nonsense submitted by someone who has not logged in. If possible, contact the submitter by user-talk first and tell them about your concerns. They will almost certainly oblige. As always, assume good faith.'

Bugs
! Piston can "burn out" in a state simultaneously powered and un-powered. --Munin295
 * 1.9pre5 1clock piston bug.png To reproduce: The image shows two different 1-clocks (powered by the same torch). If you attach a piston and block to the right 1-clock, it works fine. If you attach a piston to the left 1-clock, it works fine until you add a block—then it "burns out" in a state that appears to be both powered and un-powered. It's then actually possible (in Cr at least) to reset the piston by destroying the extended arm (without destroying the piston). --Munin295
 * To reproduce: create this BUD flip flop, place a block here, the piston will now be in a bugged state.

! Wire-after-Repeater Connectivity Bug #2 When a repeater powers redstone dust, blocks placed to the left or right of the redstone dust (with the repeaters direction being "up") are not powered. http://imgur.com/a/6tzC9 (better pictures) (New in 1.9p6)

! Identical mechanisms produce different results. --Munin295
 * 1.9pre6 same build different rate.png The image shows two identical piston 1-clocks with a piston attached to each one (lower right of each). The attached piston on the left extends and retracts on the expected 1-clock cycle, but the attached piston on the right extends and retracts on a 2-clock cycle. If I change the the way power transmits from the right 1-clock to the attached piston it switches to a 1-clock cycle, but if I then restore the path as shown in the image it returns to a 2-clock cycle. If I downgrade to 1.9pre5, both attached pistons extend and retract on the expected 1-clock cycle, so this may be new. In the image I am looking straight down with F3, so image shows seed and precise location, since this might be difficult to reproduce. (This all would be more easily demonstrated with a video but I'm not set up for that.) --Munin295
 * I tried moving the left mechanism two blocks to the left in case the mechanisms were interfering with each other via the Piston Quasiconnectivity Bug. Now both attached pistons are extending and retracting on a 2-clock cycle. Weird. --Munin295

undefined A trap door is able to remain even after the block it was placed on is separated by retracting the trapdoor with a sticky piston. -InspiredNoob
 * It's certainly a bug, but I know a lot of people who'd really like to be able to have freestanding trap doors. —Immute [talk]

? If a piston interacts with a vine, the vine completely disapears, along with these other blocks: sapling, dead bush, fern, grass, (Please help test more of these blocks) -InspiredNoob

undefined Pistons on the bottom layer of the world are not able to receive power if they are placed horizontally. This is not true for dispensers.

undefined Sometimes, Redstone torches do not update when placed ontop of each other (to transfer the current upwards). (exemple: http://dxhosting.net/dlp/uploads/pictures/2011-11-12_00.13.35.png)

X If sticky pistons retract too fast while it has a block, the block will be left behind.

X In double door setups there is always one door open when it has a redstone object nearby.

Fixed/Skipped
!s Piston Quasiconnectivity Bug A piston can be powered by a block that is not directly adjacent to it, but diagonally above or 2 blocks above. However changes to these blocks will not propagate updates to the piston. However, when the piston is caused to update by other means, it will take into account the state of these nonadjacent blocks. This list seems to have originated from this image:
 * People keep reposting this bug here, unaware that it had been addressed in the 1.9pre5 list. I'm copying it over so that everyone is aware of its status.  Please don't remove. —Immute [talk]
 * This is intentional, Jeb even proves it in his "Pistons in progress" video.
 * Can you tell exactly where it is proven to be intentional? it certainly isn't in that video. This bug has plagued everyone who ever tried to make a construction with two layers of pistons above each other, since they cannot be controlled separately and behave really strange. It is also very counter intuitive to new users, and it makes absolutely no sense at all.
 * He said he won't fix it as people use it in designs. (Look on his twitter, he said it about 3/4 days ago) Cool12309(Talk

Bugs
! Wooden doors can no longer be opened by left-clicking or right-clicking on them, however they can still be opened by using Redstone. Jeb already is aware of this.

! Trapdoors no longer open by right clicking them when there are others nearby - causing a hard time to try opening 6 at once --Anon

! cr Water destroys End Portal blocks, leading to a possible "permanently trapped" condition in the End in Creative.--PlNG 01:56, 12 November 2011 (UTC)

undefined Leaves can be destroyed quicker with a pickaxe (instantly with a diamond one).

undefined The properties of glowstone are now incorrect. (Aggregating a bunch of bug reports here.) Buttons, levers, redstone dust, etc. can no longer be placed on glowstone. Fences won't attach to glowstone anymore. It looks like we have a coupling problem here. You (Jeb) probably had to change glowstone to "transparent" to make it light correctly (now shadow gradient, etc.). But "needs to be rendered in a special way" and "has transparency, so redstone dust, etc. looks stupid on it" are orthogonal concepts. I hope there's an easy way to separate them, since we'd really like to be able to have our cake and eat it too! :) —Immute [talk]
 * Confirmation: glowstone no longer blocks diagonal redstone signals, which is another attribute of transparent blocks. –Ahruman
 * Glowstone should be reverted to how it was before. This is a resurgence of the properties it had in 1.6.0-1.6.5. The original lighting issue that instigated this change for 1.9p6 wasn't a problem with glowstone to begin with, it's a problem with glass. I've created a new annoyance report for this below. --OSX2000 01:24, 12 November 2011 (UTC)

undefined Left- or right-clicking on a closed trapdoor, that is sideways adjacent to any open one, does not open it and closes all surrounding trapdoors.

?Ice is no longer obtainable with the Silk Touch enhancement; water is produced as usual.
 * Jeb said he "fixed this in an unsatisfactory way" by removing it from silk touch. He might improve on it.  I suggest that upon entry to the Nether, water buckets turn to plain buckets, ice and water (8, 9, 79) simply disappears from inventory, and a loud hiss and particle effect similar to lava touching water emanates from the player.  This way players are allowed to keep ice in the Overworld and End, and enhances the atmosphere of the Nether.--PlNG 01:45, 12 November 2011 (UTC)

Annoyances
a Double slabs, silverfish stone, end portal frames, end portal blocks, melon vines and pumpkin vines all have no item name when the mouse is put over them. All these blocks can be obtained with the /give command on unmodded servers, and some can be obtained via silk touch.

a End Portal blocks do not show the portal effect when viewed from underneath

a Several blocks and items are not stackable for no reason and therefore need extremely many space in the inventory and in chests: -signs -doors -boats -minecarts -chest minecarts -furnance minecarts


 * As Notch said, he wants minecraft to be as realistic as possible. I don't think you can stack a vehicle with huge furniture stored inside it in real life :)
 * By that reasoning: I don't think you can easily stack 64 Blocks of 1 cubic meter of stone and carry it around in real life.
 * I don't even think these items were stackable in the first place.
 * I think that was the point. They were not stackable in the first place, but there is no reason for them not to be. So this would be a valid bug. --Gitterrost4
 * Until Mojang states that these items should be stackable, this issue fails to meet the definition of a bug (unintended/malfunctioning behavior). Moving to Annoyances. 24.89.232.132

a Signs and Chests are missing their "cracking" animation.

a Pressure plates on fence posts (as in tables in NPC Villages) are activated even when touching them on the side. This generates annoying clicking sounds when players or villagers are walking around in these houses. (Does not appear in multiplayer currently as pressure plate sounds don't work there). -- JonHa97

a While Clay Balls are craftable into Clay Blocks, Clay Blocks are not craftable back into Clay Balls.

a Fence gates cannot be activated/deactivated using redstone

Bugs
!  Minecraft does not ship with the latest version of LWJGL, which causes stuck keys and other issues on Linux and Mac OS X.
 * I have this issue with stuck keys on Windows, also when updating LWJGL. believe its a myth that it is restricted to Linux/OSX/Specific versions of LWJGL. --zerpa

undefined Double tapping the sneak key while walking causes the player to start sprinting.
 * This is not a new issue - I used it in 1.8 (see also Sprinting). This might, but mustn't, be a feature, intended for people who would like smoother transition between walking and sprinting.
 * I know it's not new. I've also been using it for a while. Still, it's a bug...maybe.

undefined At night, a bed cannot be entered while standing on top of it. However, when trying to do this at daytime, the message "You can only sleep at night" still shows.

undefined You can't hold down the left mouse button to continuously attack anymore; instead, you have to click it repeatedly.
 * Intended behavior -- Mustek
 * I was (quite correctly) regulated earlier when stating this. Do you have a source for that? --Gitterrost4 02:01, 12 November 2011 (UTC)

undefined You can't hold down the left mouse button to break a minecart anymore; instead, you have to click it repeatedly.
 * Intended behavior -- Mustek
 * How can this be intended? Give me one good reason for this behavior. --Gitterrost4 02:01, 12 November 2011 (UTC)

undefined Getting in/getting out of a boat/minecart will make you use whatever item you're holding (If you hold a bow and try to get out of a boat, you will shoot it as you leave the boat)

undefined Experience gained from ender dragon is lost after credits; tested in both SMP and SSP

undefined sp When under a 2-block high ceiling and next to a redstone repeater you can fall through one level of blocks. www youtube com/watch?v=PpES-DSC8PM Video gives a good description of how to reproduce.
 * Also works with closed trapdoors instead of repeaters and also works with mobs (like snow golems) instead of players -- JonHa97
 * In smp player will bounce right back immediately -- 93.106.77.77 22:02, 11 November 2011 (UTC)

x The Eye of Ender, when thrown, clips through blocks and is lost, which uses up way too many eyes when looking for a Stronghold. Private meta

undefined Killed by lava and drowning in water multiple times, but there were no deaths counted on the statistics page.

Bugs
! Very annoying Z-fighting between water and glass when underwater. Also happens between water and lava. The slightest movement causes the interface between the two z-fighting elements to flicker wildly. See images below. This is a longstanding bug.

undefined There is a major bug with the "critical hit" particle's texture. (No, reddit, I will not flag this bug as [!!], even though it would be funny.)

undefined Instead of rotating about its center, a dropped chest now rotates about its left top corner.

undefined The armour meter does not go down according to uses left on the currently equipped armour. This provides the illusion that the player is invincible while taking damage Later, when all armour is depleted, the meter goes down from full to empty in an instant.

undefinedmp Magma Cubes don't show their "accordion" jump animation in multiplayer. KoreRekon

undefined Some texture overlays on entities, such as glowing eyes or hurt colors, and chest lids, are Z-fighting with the underlying texture:

undefined When wolves enter water, their skin turns black and remains that way. Only able to test with aggressive dogs.
 * Edit: Works on all wolves, but only at night, or in areas with no lighting. There is a slight change during the day.

undefined In some phases of the moon, the shadow is square, while in others, it is convex-circular, and in others still, it is concave-circular. Are we supposed to infer that the earth is sometimes round and other times square? (Confirmed via minecraft.jar/terrain/moon_phases.png. What is this doing in "terrain"?)
 * You realize the phases of the moon are made by the angle of the sun relative to the moon, and not by the shadow of the Earth, right? The only "inaccuracy" here is that the moon and sun are always directly opposite, so the moon wouldn't even have phases.

Annoyances
a! The grass/water colour in the biome boundary between swamps and other biomes does not fade out/in, making it a visual annoyance.

a In the menu, when you try to press any button you get an error saying "You haven't bought Minecraft. Please purchase at www.minecraft.net and then try again"
 * Can't reproduce. Which menu are you talking about? Are you logged in legitimately? -- JonHa97

a In the Video Settings menu, the warning message that appears when you select Far render distance on weaker computers is obscured by the Particle options.

a In the ending, there is a typographical error: "...the player started to breath faster and deeper and realised it was alive..." The text uses the noun "breath" instead of the verb "breathe".

a The speech before the credits scrolls too fast to narrate and might be fast for some off the younger players.

a The winning text (win.txt) refers to the player repeatedly as "it"/"its", which is an ungrammatical way to refer to a human being in English. A more acceptable choice would be "they"/"them"/"their"/"theirs" (as determined by context; I don't trust Notch not to nitpick over my nitpicking; that one is a prankster, it is), although some purists would object to that as well, but it is still far better than "it", which is decidedly wrong.
 * Could this not be intentional? Some beings talking over the "lowly human" as "it"?--Gitterrost4 21:55, 11 November 2011 (UTC)

a! If a texture pack uses a tile size other than 16*16, it will cause graphical issues and custom animations will not be shown.

a If a tree spans two biomes, it may cause an overlap of leaf blocks so that there is contrasting-coloured foliage on the same tree.

a On lower-end computers, the debug screen is mostly unusable because the FPS graph obscures most of the information in the upper-left. This information should appear above the graph, not below it.
 * That always has happened. I should know. My laptop runs 3 FPS. Vista, before you ask.
 * But it is still a bug, so should be listed.

a While you're in bed, the experience level number doesn't fade out.

a While in 3rd person mode and the player is in water, the screen turns blue even if the camera is not in the water. The inverse can also happen.

a When an enchanted item is dropped, it does not show the sparkly overlay.

a On Default Texture Pack, in SMP (at least), filling empty bottles with water (from cauldron at least) will make the empty bottle disappear, but not add a "water bottle" to your inventory. Can be fixed by opening anything with a GUI (like a crafting table). However, opening the inventory itself does not fix it. AMOE

Bugs
! Smooth lighting is not applied to both still and flowing fluid blocks. Instead the fluid will have blocky lighting.
 * Been around since smooth lighting was introduced. - IPeer
 * It's a bug, it's in 1.9p6. It belongs here
 * Correct. If this is a bug (as I believe it is), and it is still in 1.9pre6, then it belongs here, regardless of when it first appeared.  Jeb has stated that he looks only at the most recent version's issue list and has instructed us to list *all* issues there that still apply. —Immute [talk]

! Some torches generated in abandoned mine shafts or NPC villages don't light anything up, unless replaced or if another torch is placed by it.

x Light does not pass through the gaps in slabs, and creates this weird light setup

x If there is a block directly behind glass, it appears dark even though light should pass through the glass. 

x Light "leaks" through the corners of stair blocks: example image

x Light "leaks" through the corners of piston blocks: example image

x Swimming 1-block high mobs are very dark. Totally black at night. The lighting flicks between light & dark as they bob in the water.

Bugs
x In the credits, after killing the boss mob, the name "Patrick Geuder" has the wrong color, compared to the other names.

! The Enderdragon does not spawn on maps where the End has been accessed before 1.9 pre6.
 * I think that this should be classified as an annoyance, it's definitely very low priority since these bug fixes should be catering for newer worlds rather than past ones. 58.169.254.156 00:56, 12 November 2011 (UTC)

! The player loses all their experience after going through the exit portal out of the End.

? After returning to the world after defeating the boss there is a glass pillar above the stronghold where the portal to the end is, not sure if this is a bug or not.

? The Enderdragon destroys TNT rather than igniting it.

Annoyances
a!cr End Portal frames are destructible in Creative Mode, but are not in the item selection. End portals themselves are also destructible in Creative Mode, however, that would not matter if the portal frames were available, as they could easily be rebuilt.

a! End Portals are permanently destroyed when water is poured on them. Doing this to the exit portal out of the End will make it impossible to leave the End without dying.

? It is unknown if this is a bug or not, but the player loses all their experience after going through the exit portal out of the End.

Bugs
x In the Nether, when reaching a Nether Fortress, the blocks I place transform into nether bricks. When these bricks are destroyed, the next items placed are normal. See documented in youtube video ai4m4iAx1Zw. Also, in this seed there are almost endless nether brick walkways, not sure if it's intentional or another bug. Private meta
 * I was not able to reproduce this issue, and my area looks slightly different from yours, I don't know how much mining you did prior to the video. Are you testing with vanilla minecraft? Nice find on getting a seed with the most complex nether fort and biggest nether fort i've ever seen in close proximity to the other.

Bugs
undefinedcr Minecarts will drop a minecart when destroyed in creative mode. As a result of this minecarts tend to quickly fill up the player's inventory in creative mode. (ie: blocks are not supposed to drop items in creative)

undefinedcr When in the item selection screen with a block or item that is distinguished by damage value; Wood, Wool, Half Slabs, Dyes, Stone Bricks and Saplings, trying to remove it from the inventory by placing it on one of its damage value counterparts will not delete it, but instead will add more to the stack. Example: taking a red wool block and dropping it on any other wool block will not delete it, but will simply grab more wool, as if the user had clicked on the red wool block. -Akyute 21:02, 11 November 2011 (UTC)

xcr Breaking a TNT block in creative still drops the TNT block.

undefinedCr If you try to destroy a powered piston or sticky piston in Creative by clicking on the extended arm, the piston drops as an entity instead of being destroyed. --Munin295

 * a 44:6 Alternate Stone Slab (ID 44:6)
 * I have posted a screenshot of the alternate stone slab (44:6) and double slab (43:6) on the left, and the normal ones on the right. As the alternate double slab provides an alternate appearance, it would be useful to have for aesthetic purposes. -Gravemind2401

Sound
''The new sound files have not been uploaded to the download server yet. This means that the chests, endermen will have sounds in the final release.''

Bugs
! Major sound mixing problems. Note blocks are way too quiet; I can barely hear my notification chimes over the sound of nearby cows. Doors, cows, way too loud. Portals way too loud; also portal noise should drop off with distance much more sharply (certainly not in a linear fashion). Really breaks the experience.

x Mobs have a tendency to make ordinary (not damage- or death-related) noises right after they are killed.

x MP Ambient cave sounds never play in multiplayer. Also, if possible, it'd be nice if the cave sounds were generated server-side, so that people in similar locations would hear them at roughly the same time.

x Rain does not always generate the rain sound.

x Placing a water source at the feet of 500+ mobs standing in a single square produces a very loud sound equivalent to a small army of creepers detonating simultaneously (there is no limit in the amount of sounds playing at once).

x Walking across a series of trapdoors does not make any sounds. Walking across the edges of blocks adjacent to the trapdoors (i.e., walking across the top of the block containing the trapdoor) makes the walking on wood sound.

undefined Oceans still have pockets of air.

! In singleplayer, some chunks will generate oddly, not in accordance with neighboring chunks. They may be far above or below other chunks, and may be different biomes. Water does not fall off of these chunks. When the player travels over these chunks, the "Saving Chunks" screen appears, and the client crashes.

a! Creeper damage is not changed depending of the difficulty, resulting in almost 5 times the Easy damage currently (24.5 hearts point blank) than from Beta 1.7 and prior (5.5 hearts point blank).

a Snow golems' snow trails do not melt in warm biomes (like grass and forest) so creating a few golems can make a large area look ugly very fast, which can be used for griefing. Additionally, it is very difficult to clean up all the snow without external tools/mods.
 * Perhaps rain could melt snow? JonHa97

a Sometimes if you enter the end and you lose from the ender dragon and go back. there will be 3 ender dragons which you can hurt but can't kill because they have no health bar. and they might destroy your way out and the dragon egg because they can destroy portal and the dragon egg.

a Minecraft_server.jar needs to be multi-threading to offer better performance for multi-core servers. A server.properties configuration setting the amount of threads to create in a thread pool used by the server would be really nice, too; so minecraft_server doesn't eat up resources on all cores when server admin feels there's need for other things to co-exist.
