Crashing/System

Bugs

[!!] After closing and re-opening a world, Minecraft went to the dirt background and subsequently crashed. I've tried to reproduce but it doesn't seem to occur again

[X] I was doing a stress-test with 3000 XP orb entities (1 frame/5 seconds), and after they got insta-del by a cactus the framerate instantly topped back to 40 (the limit) but the game took 5 seconds to speed back up from a slow-motion sort of speed. During this time (at smooth framerate) the player moved very slowly, with low gravity, and the rest of the game world seemed to fast-forward (mobs, item decay, time of day).

  • How to reproduce: Build a glass cabin. Get Instant Health II splash potions, Zombie egg and Cactus. Remember to build it on sand. Next, get a macro-clicker because you'll need about 400 zombies, don't go any further risking a crash. Then, close the cabin up and kill them with the potion: this will prevent the orbs from coming to you as they spawn. Quickly collect the drops from inside the box, leaving the xp confined. Next, spawn a zombie beside you on the outside. Notice that the lag from the thousands of orbs is extreme with FPS nearing zero. Watch this zombie for two or three minutes, then break the glass and replace it with cactus. The XP orbs will be deleted by the cactus, then the zombie you just placed will speed up crazily and you will have moon jump for ~5 seconds.
  • Reproduced in 30e. --Steve G. Wood 14:41, 25 July 2012 (UTC)

[!] Minecraft will not save world progress when reloading a world in some computers (such system include: 1.75 GB of RAM, 32-bit, 2.71 GHz, Windows XP SP3, Java 1.6). Example on a newly generated world: http://imgur.com/a/IodIc#0 --Manuelschi 14:52, 25 July 2012 (UTC)

Annoyances

[A!] [SP] When loading or creating a new world, the loading screen with the dirt background says Loading chunks, adds Building terrain, then the main menu then flashes up, then goes back to the dirt background which briefly says Downloading terrain, then flashes the main menu up again, before showing the world. --SpokeHD 14:43, 25 July 2012 (UTC)

Gameplay

Bugs

[!] Traveling to the Nether still frequently drops the player out of the world, resulting in death and loss of items/xp. A first trip to the Nether usually functions normally, but repeat trips often result in said bug. 70.179.147.135 09:51, 25 July 2012 (UTC) [sorry, forgot to sign]

  • I have two portal in overworld that go to same portal in the nether. When I enter the nether through second portal and return, I fall out of the world. Maybe the chunk with primary portal is not loaded properly. If I save the game in nether, it works ok. 212.226.57.220 14:51, 25 July 2012 (UTC)
  • When this happens, you can quickly save&exit and reload. This often saves you from dying.

[!] After his death his spawn point changes, precluding the gameplay of some custom maps, and compass does not point to their spawn point. NOTE: also the definition Without the bed, the bed works, the problem is with the natural spawning

[X] [MP] When teleporting to the nether the server lags. A noticeable spike on the server client appears also. Screenshot: [[1]] --derksthename

Annoyances

[A!] Sometimes, eating food once will result in it being eaten again, consuming another item, restoring health but showing no animations or particles. Elite6809 (talk) (forum) 10:01, 25 July 2012 (UTC)


[A!] Linux Numbers for changing quick-bar selection are not functional with Czech keyboard. Working on Windows without any problems. --Sejsel 10:09, 25 July 2012 (UTC)

[A!] Leaving the end with any potion effect removes the effect after spawning in the normal world. --Fluffyman24 10:18, 25 July 2012 (UTC)

[A!] Mobs spawn on non-natural occurring blocks Djerun 12:47, 23 July 2012 (UTC)

  • See discussion talk:Known_bugs/Version_12w27a#Mobs spawning on 'non-natural' blocks --80.134.11.177 12:52, 23 July 2012 (UTC)

[A!] Sometimes leaving or entering the end will show that you have no xp however once 1 xp is gained the xp will be back. --Fluffyman24 10:18, 25 July 2012 (UTC)

[A] The builtin "speedhack" detection breaks elevators and other legitimate piston contraptions that transport a player "too fast". It manifests itself as getting stuck in the device due to the movement, caused by the piston pushing the player, being denied by the server. This used to be an issue on MP only, but now that the client is effectively a server as well, it affects SP too. --Ntt 13:13, 25 July 2012 (UTC)

  • (Merged duplicate) pistons are allmost fixed but these piston elevator's still don't work properly. they push you up 5 block before you get stuck inside an extended piston arm.--League

[A] macOS [Cr] When flying at high altitude, or with a large drop below you, the double tap sometimes no longer lets the player fall, forcing you to either switch to survival mode to get to ground level or very slowly descend with shift. I know this is due to lag but is there some way to get around it? --SpokeHD 15:15, 25 July 2012 (UTC)

[A] [MP] We started a server and decided we didn't want any user to be OP'd because we want pure survival, but because of spawn protection no one can edit the spawn area. I'd just like if you could add a toggle to turn off spawn protection in server.properties. --Pizza2004 17:14, 25 July 2012 (UTC)

Blocks

Bugs

[A!] Can't place halfslabs between small gaps (12w30e)

[X] Tripwire hooks makes randomly block updates. It can be seen when tripwire hooks are connected to blocks that BUD or TBUD check. I connected about nine tripwire hooks to TBUD and it triggered quite often. Screenshots of that "one bit random generator":

Tripwire hooks are not connected to anything and there is no other tripwire hooks.


[X] When breaking the new rotated wood they are placed in your inventory rotated and always saying Oak Wood, though they have the correct texture. This appears to be purely aesthetics. see screenshot --Mag0ca 11:05, 25 July 2012 (UTC)

  • I could only reproduce this rotation in the inventory using silk touch enchant. Punching the block or using a normal tool, they stack on the appropriate texture stack. http://i.imgur.com/gABlD.png

[X] Redstone circuits still freeze after returning to the scene after wandering away. The circuit needs a kick to start again, like you do with a BUD Video --ABrightmoore 11:50, 25 July 2012 (UTC)

[X] Horizontal log has some transparent lines between the blocks. Screenshot. Vertical ones work properly. --YSelf D de.MCWiki-Admin 13:01, 25 July 2012 (UTC)

Annoyances

[A] When Mob Spawners spawn FallingSand entities, they will often fail to place and instead drop as items. It might be beneficial to have an additional parameter dictating if a FallingSand entity should drop an item if it fails to place. --MegaScience 11:48, 25 July 2012 (UTC)

World Generator

Bugs

[X] Sometimes there are cave entrances that are created in the the desert wich are made out of sand which is floating in the air... --201.229.35.75 13:35, 25 July 2012 (UTC)

[X] The world generator seems to generate "world cuts" more frequently than in previous snapshots. I created ca. 10 worlds and two of them contained abrupt transitions between biomes. (sorry for my English) --Pureprogger 15:14, 25 July 2012 (UTC)

Mobs/NPCs/Animals

Bugs

[X] Slimes are taking over again in Flat worlds. The previous improvement to reduce their number in Flat worlds since 12w25a seems to have disappeared (at 12w30a or earlier).--Jovet 10:52, 25 July 2012 (UTC)

[X] mobs still fall trough the ground a lot. mostly npc's who sink halfway through the ground.--League 09:56, 25 July 2012 (UTC)

[X] mobs like cat's and wolf's get stuck inside blocks. my cat walked straight into a glass block.--League 09:56, 25 July 2012 (UTC)

[X] zombies are much less persistent. one was following me. I ran into my house and closed the door. he started to destroy it. when it was allmost destroyed he just stopped and walked off. I was playing in survival mode on hard mode--League 11:39, 25 July 2012 (UTC)


[X] squid movement is very lagy. the way they randomly change directions and the way their legs flickre between open and closed position.--League 09:41, 25 July 2012 (UTC)

[X] There are different hights in the water. Only saving and reloading the world fixes that. Note that I have world from version 1.2.5! Maybe that's the reason.

[X] Endermen when hit at night start vibrating weirdly, and their head pops up which shows a strange glitchy neck... it was hard to get a good screenshot but this was the best I got: Screenshot --SpokeHD 15:38, 25 July 2012 (UTC)

  • Not a bug, intentional. That's what an angry Enderman is supposed to look like, shaking with rage and all. --82.69.54.207 16:14, 25 July 2012 (UTC)
  • I guess I can understand the shaking, but the see-through glitchy neck looks really weird. Check the screenshot I linked or try it in game, its hard to describe. --SpokeHD 17:04, 25 July 2012 (UTC)
  • Yes, I've seen it in-game lots of times. I agree it's weird, but it really is intentional. Scout's honour! --82.69.54.207 17:20, 25 July 2012 (UTC)
  • No bug here. Endermen have always been like this. 69.113.144.41 17:27, 25 July 2012 (UTC)

Graphical/Lighting

Bugs

[X] Lighting bug occurs on some blocks if Smooth Lighting is disabled. Screenshot of the issue: i imgur com/6MP5P.png - Intel HD Graphics 3000, Windows 8 RC 64-bit. (note: link intentionally broken because the wiki fails to detect when I submitted the captcha properly.) --98.71.68.52 14:04, 25 July 2012 (UTC)

  • This is not restricted to normal lighting. --Steve G. Wood 14:45, 25 July 2012 (UTC)

[X] the warmer red torch-light and fire-light which was added in 1.8 doesn't work anymore on most laptop's . on my friend's computer it still works. But on my laptop the light aminating from my torch is just the normal sun-like light.--League 09:48, 25 July 2012 (UTC)

[X] fast spinning spawners are still broken--League 10:02, 25 July 2012 (UTC)

[X] when you shoot an arrow at a mob or another player it doesn't stay stucked in the player.--League 09:51, 25 July 2012 (UTC)

  • This was removed a long time ago. -- Mustek 11:07, 25 July 2012 (UTC)
  • it's a shame but you're right, I hope they will re-add it one day.--League 12:29, 25 July 2012 (UTC)

[X] arrows wich have been set on fire by shooting them trough lava don't set the mob they hit on fire anymore.--League 12:29, 25 July 2012 (UTC)

[X] Inverted slabs with blocks above them STILL have incorrect lightning... (Screenshot) -- Mustek 14:30, 24 July 2012 (UTC)

[X] macOS Large areas of black shadow under overhangs, particularly in Extreme Hills biome. It goes away after a few seconds if you go near it. Screenshot --SpokeHD 14:23, 25 July 2012 (UTC)

Annoyances

[A!] XP Orbs will crowd around the camera while they are being collected. This is extremely annoying, especially with ghost orbs. media:Annoying_orbs.png --Steve G. Wood 14:43, 25 July 2012 (UTC)

Sounds

Bugs

[X] there is still one nether portal sound missing. it's the sound you hear while transfering to another demension. this is what I mean. you hear the sound when it sais : entering the nether in the video.--League 09:53, 25 July 2012 (UTC)


Annoyances

[A!] [MP] Footstep sounds and possibly some other sounds like splashing into water - eating are delayed depending on the player's ping(server-sided) which is really annoying(This was in the older snapshots too) --Crashty

[A] [Cr] in the potions part of the creative inventory, the healing and instant damage potions are missing. there are only their splash potions variants (this bug exists since the new creative inventory) --YellowMiner 14:57, 25 July 2012 (UTC)

In-Game Interfaces/HUD

Bugs

[X] In creative mode in the survival inventory, the chest armor slot is moved and you can't put anything in it. Redstonehelper 11:19, 25 July 2012 (UTC)

  • In creativemode i can't interact with the chest armor slot.
  • Merged duplicates. It 's because there is a "ghost slot" over the chest armor slot. it only cover up to the 4/5 of the chest armor slot, so if you put your armor on the top of the slot, it works. --YellowMiner 14:54, 25 July 2012 (UTC)

[X] A fuel-charged furnace with no fuel in its fuel slot will have the fire icon reset to 100% at chunk reload.The fuel indicator will be stuck at 100% until the last heat unit from the spent fuel piece, at which it will descend to zero percent. An invalid item in the fuel slot, like an empty bucket or other junk, will not make it display properly either. How to reproduce: Place a single piece of fuel & some input in furnace, log out or move away until chunk unloads,return and open up furnace interface.Cytokine 17:41, 25 July 2012 (UTC)

Annoyances

[A] when you are writing a book and you notice you made an error a fiew sentences back. you have to delete all the sentences to fix your error. books should have a cursor which you can controll with the arrows.--League 09:34, 25 July 2012 (UTC)
