Minecraft Wiki:Issues/1.2 Preview

Organization of This Page & Instructions
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.

If you're unsure of an issue, it's good practice to post about it on the |talk page to see whether others can reproduce it. Make sure you're testing the bug in the correct version (for this page, that's 1.2 Preview) with no mods installed. Also, make sure to proofread your issue report before submitting it; unintelligible issue reports come off as inconsiderate and disrespectful. Finally, please determine which game mode(s) your issue appears in, and flag it with the appropriate label(s). (Also, note that if, for example, a minor annoyance appears in both single-player and multiplayer, and in both creative and survival modes, you should label it as a, not aspmpsucr.)

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 USA keyboards, and to the right of  on British keyboards).

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.

Issue Labels
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! =  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.
 * undefined =  undefined  = Minor bug.
 * a =  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 =  sp  = Single-player.
 * mp =  mp </tt> = Multiplayer.
 * su =  su </tt> = Survival mode.
 * cr =  cr </tt> = Creative mode.

Labels for indicating that an issue is restricted to a particular OS:
 * =  </tt> = Mac OS X
 * =  </tt> = Windows
 * =  </tt> = GNU/Linux

Labels that Mojang (not you!) uses: (Please place these tags in front of existing issue labels; do not remove the existing labels.)
 * f = Issue for which a fix will appear in the next update.
 * n = Not a bug; intended behavior. By definition, this label is inapplicable to annoyances; annoyances are not bugs.
 * s = Issue that will not be fixed in the next update.
 * u = Issue that Mojang has tested but was unable to reproduce.

To produce these labels, use the following code:  </tt>c </tt> 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 </tt>.

Crashing/System
Bugs f spcr Created a single column of Glowstone up to 256, and got a "saving chunks" crash, logged back in and it kept crashing, shortened the render distance and still crashed.--Sxerks 17:51, 29 February 2012 (UTC)
 * Confirmed. Error message: http://i1098.photobucket.com/albums/g368/j1k3bucket/mcerror.jpg --J1k3

!! ? When you go to options and click on controls the game crash.
 * Could not reproduce, mod related?
 * Only mcpatcher for hd textures that most of the players use... ill try whitout the mcpatcher...
 * Tested whitout the mcpatcher... still crash...
 * Try removing .minecraft/options.txt, see if that fixes it. -- Orthotope

f spcr Created a single column of stone up to 256 in nether and was able to place lava on to of it and got the "saving chunks" crash, logged back in and it kept crashing.
 * Error Message: http://pastebin.com/yx5C3CZg --VeraLapsa
 * Same error as the lighting one above, fixed. Dinnerbone 21:42, 29 February 2012 (UTC)

Annoyances a In the video settings menu when cycling/clicking through the gui scale option, clouds will be toggled on/off.

a In the F3 menu the system usage spikes that scroll across the screen cover over the text of the game, including the buttons from the escape menu. This isn't problematic on fast systems or large screen systems but smaller screened and slower laptops it is unreadable at times. Should be behind text and menus.

Fixed/Skipped

Redstone/Pistons
Bugs undefined spsu Piston heads frequently fail to push the player. The same occurs with items.

undefined When you stand on upside down slab and push it up by piston, you will fall through the slab. Annoyances

a! Redstone torches burn out promptly upon receiving power, and will continually burn out immediately after being powered. Fixed/Skipped

Blocks
Bugs undefinedcrsp When breaking the top half of a wooden door in Singleplayer Creative, the door drops as an item, when you break the bottom half though, it doesn't drop as an item. 90.231.9.197 18:30, 29 February 2012 (UTC)

undefinedcr When you break TNT in Creative it drops as an item.

undefined When placing blocks on vines, it replaces the vines.

undefined Upper slabs cannot be placed above redstone for a flush covering. -PurpleTarget
 * Not a bug; you can't put two blocks in the same cubic-meter space. -- Orthotope

Annoyances a Upside down stairs and slabs are generally difficult to work with since the only way to get one is to place the stair/slab on the underside of a block. If you place a slab on the side of an upside down slab, another upside down slab should be created instead of a normal slab. This will allow for faster upside down slab roof creation.
 * For placement of upper slabs, being able to place upper/lower slabs based on targeting the upper/lower half of a block side would make things much easier.
 * Alternatively a keyboard shortcut command (like holding a key down) to place the block in the upside down position in the normal block space would be likely easier, more extensable, and be able to allow for more up-side-down blocks going forward. Having to divide each block in half to determine targeting would be more difficult to implement without breaking or making difficult other block placement.

a In 1.2, you added the ability to place torches on top of upside down stairs. However, one cannot place a torch on a upside down half slab, though this makes no real sense. Note that one can place a torch on a double-slab block, and the upside down half slab is at the same level as it is. -otto4242

a Many other blocks/items (redstone and doors for example) cannot be placed on the topside of upside down slabs.

Fixed/Skipped

Crafting/Enchanting/Brewing/Interface
Bugs undefined Instant Damage Splash Potion II does not hurt skeletons and zombies, only creepers. It does heal the skeletons and zombies to max health. Been like this the last few snapshots. Not tested in single-player. Video of bug: /watch?v=r-eSgN0-R8E
 * This is intentional. Undead Creatures like Zombies and Skeletons are healed by Damage potions. They are damaged by Healing potions. --91.0.55.126

cr When you throw a item/block directly from the item interface in creative mode on the ground and u pick up the item without closing the item interface, items/blocks in the item interface are temporary replaced by the item u just dropped. (I think it's on the same spot as the item would appear in your normal inventory)

Annoyances

a! The enchanting system has always, and continues to be frustratingly unfair. sometimes producing Efficiency III when a level 50 enchant is used. Considering you need to kill NINE HUNDRED AND TWENTY FIVE zombies/creepers etc, to get to Level 50, users are naturally in consensus that, to quote Yahtzee Croshaw, the ratio of difficulty to find versus actual usefulness is completely arbitrary. While we respect the mystique Mojang have tried to create about enchanting, the numbers need serious review. Kizzycocoa

Gameplay
Bugs !cr When flying in liquids, horizontal movement is slowed to a crawl, while vertical movement is very fast. This is an old bug that has been around since Creative was implemented.

undefined cr When dyeing sheep, taming wolves and cats, and healing wolves with meat, the items are used up.

Annoyances a Mushroom Stew doesn't stack, despite being effectively the same as stack-able cooked meats. Fixed/Skipped
 * This is a feature. But i agree it is slightly annoying, (you could drop the empty bowl if your inventory is full like you do when filling bottles with water). ZuppaHD
 * It would have been a feature when it had separate healing powers and deserved to be treated differently from other food. Not any longer.-PT

NPC/Animals
Bugs Annoyances a Since pigs' meat is equal to cows', and they drop less meat than cows (and even have a chance of dropping no meat at all) there is no good reason to keep pigs rather than cows.
 * Not a major, bug-level annoyance. -- Orthotope

a Mobs utilizing the new AI system will wander directly into the Void if it is 1-2 blocks below. This appears to be due to only checking the amount of air blocks they would fall. The old AI system would prevent mobs from wandering into the Void.

World generator
Bugs ! Mushrooms spawn on top of the Nether.

! Big mushrooms don't spawn on mushroom islands.

! No snow biomes(Forests with snow) --Kain837
 * sp Could not reproduce Minecraft5025 23:36, 29 February 2012 (UTC)
 * Minecraft5025, you should not be using the u label. Please read the instructions at the top of the page, as some labels are reserved for Mojang use only. I have removed your use of the label. CaMoreno3 02:44, 1 March 2012 (UTC)
 * The Taiga Biomes are there but no trees in them or just the occasional, probably has to do with the tree bug below --Kain837
 * Confirmed on seed 98769856965959 x-299 z207 Taiga labeled biome with no pines. Single player survival generation with structures. --- Kittani1977

! Again, Birches and pines spawn rate is very low. --Galaxy_2Alex (Talk)

! spoffline. There is definitely something broken in the biome code since the map height is extended at 256. In the normal forest there are no birch trees (I can't find one in about 10 maps in creative) and the trees are all the same height (no big trees). The swamps are broken too, the trees mostly stand in the water, so no mushrooms can spawn. I also couldn't find a pine tree forest. In some snow taigas there were isolated pine trees. The biome generation is not as it was before the extension of height.

Some examples for normal tree forest with same trees and no birches. 6203567990940513874 x:-239  z:256

--reptile311

! No Trees growing in Tiaga Biome, or on land in Swamps (Which also impact mushroom populations in the latter) - PurpleTarget
 * It's the same as the 4 posts above... --Galaxy_2Alex (Talk)

Annoyances

a There should be a second superflat world type but populated with resources (so a normal world, but flat, with all biomes and grass at level 64), because, at the moment, it's making the Survival mode pretty useless.
 * This is not the place to suggest new features. -- Orthotope
 * Could be considered an Annoyance in that "Superflat World Survival", an available selected game mode, is unplayable. Kittani1977

Graphical/Lightning
Bugs

undefined Mining clay from directly above does not show mining damage texture (cracks) as you're mining it. As seen here: http://imageshack.us/photo/my-images/109/cracks.png/ EsOne

undefined Redstone lamp switching repeatedly (e.g. by clock) on sunlight makes lag, but switching in dark area not.

undefined There is some light glitches with upside-down slabs, if there is a block over, and upside-down slabs around, like in this picture: http://www.pixenli.com/images/1330553927012625800.png R-One

undefined Stairs have displaced textures on their sides when placed in north-south direction, like in this screenshot: http://i.imgur.com/u6leo.jpg They have proper textures when placed in east-west direction. This is true for all stairs, but mostly noticeable on stone brick stairs.

undefined Weird dark lines on water surface: http://i.imgur.com/jdSTQ.jpg (there is nothing above the water casting a shadow). This is a world converted to anvil by 1.2 preview. --TheMan 00:15, 1 March 2012 (UTC)

undefined Light pass through grass block as if there was no block at all. Drakray 19:41, March 29 2012 (UTC-05:00 Eastern Time)

Annoyances

a An old glitch, hoping jeb or dinnerbone will read and fix that : when sneaking, if the player skin has a hat or head accesory, it will be offset one pixel up. Also, when looking down, the player head will pass through it, removing the front face.

a Using the new top-half slabs to create a ceiling causes the undersides of the ones on the inside to become completely black. Minecrafterambesten

a In-game maps don't show snow anymore. spiderboy4

Bugs
! Several sound instances do not play:
 * Chicken egg laying sounds.
 * Pressure plate, lever, button sounds.
 * Mob/Other Player stepping sounds.
 * Other Player mining sounds (the sounds playing before the mining is finished - see Obsidian or Bedrock for examples).
 * Fishing rod sounds (reeling should not make a sound).
 * sCave sounds (or at least, they are not synchronized between players).
 * Slime and Magma Cube sounds.
 * Hoe breaking sounds.
 * Armor breaking sounds.

! A few graphical elements are missing:
 * Fishing rod "line".
 * Fishing rod "line" in held item. It shouldn't appear when the line is casted.
 * Other Player breaking animations.
 * Magma Cube animations.
 * Other player's enchanted items don't shimmer.

! Mining takes longer in multiplayer than in singleplayer. This is caused by a click-mining 'fix' that was added in Beta 1.3 and is not needed.

! Slimes and Magma Cubes randomly warp up and down when they have a ceiling above them.

! Knockback and damage screen calculation is often wrong in multiplayer, actually dealing knockback when it shouldn't (like drowning or being on fire).

! mp Huge Mushrooms planted with Bone Meal are invisible until reconnecting to the server (affects all players on the server)

undefined Player movement is not smoothed enough (the client does this) in fairly or very laggy conditions.

undefined Arrows "warp up" when shot on walls. They also disappear and become impossible to collect when shot on ceilings.

undefined The anti-spam does not really prevent spam.
 * I can type 4-5 messages a second as non-op and I do not get kicked. <font color="Blue">C <font color="Orange">ali <font color="Purple">nou - talk × contribs » 23:43, 24 February 2012 (UTC)

undefined Arrow shooting is buggy and sometimes "resets" the charging progress.

undefined The 3 second invincibility on reconnection can be exploited to be invulnerable to falls/lava/PvP/...
 * Could be intentional to be prevented being killed by griefers or by accident. ZuppaHD

undefined Having trouble making tamed wolves change from sitting position.

! Fire Aspect bows and swords light other players on fire, when PVP is toggled off.

Annoyances
a Instead of saying "Outdated Server!" when going on a 1.1 server, it says:" Internal Exception: java.net.SocketException:Connection reset"
 * Maybe that is completely comething else. Minecraft5025 23:37, 29 February 2012 (UTC)

a When connecting to an outdated server/client, protocol version/game version should be shown.

a Hitting mobs is harder in multiplayer because of lag. It is also much easier for monsters to hit players. Probably a delay before attacking (based on lag) should be added...
 * This is an annoyance, not a major bug. Orthotope
 * This is especially true with large slimes, but the issue seems to have to do with the hitbox being shifted. Some slimes can be hit (melee) from fairly far away, while others are literally impossible to hit even when the slime is jumping on the player. Shadowx4ffc 04:09, 1 March 2012 (UTC)
