Crashing/system

Bugs

[!!] Crashed when I was jumping in water and exploring new area on a newly created map. Not sure which triggered the crash. When I loaded that map again I got this error report. --MFINN23

[!!] The crash bug when you try to join a world still remains.--HawkBird 04:42, 29 September 2012 (UTC)

[!!] Created a portal to the end and jumped in crashed game

Speedyrv 9:59am(CST) September 28, 2012

  • I have recreated this on SMP. If I use 12w39a, I can log in or travel to The End without an issue. But in 12w39b, it crashes with the same messages as this crash report. --Inertia 03:31, 29 September 2012 (UTC)
  • I also have recreated this on singleplayer. Every time I try to go to the end, it crashes. 24.131.165.39 17:24, 29 September 2012 (UTC)

[!!] In 12w39a the game crashed when a minecart was placed and the world wasn't playable after this anymore.

  • The 12w39b snapshot fixes have not resolved this issue, All worlds affected are corrupt.
  • This seems to happen sometimes and not others at random. --Mattymatny 21:03, 30 September 2012 (UTC)

--☺ Sven ? ! 15:26, 28 September 2012 (UTC)

[!!] Crashes in the Adventure map Eronev 2 which was built and stable in 12w38b download it here: http://www.minecraftforum.net/topic/1479332-adv Have figured out it has something to do with the mob spawners. When all of them are removed, it loads ok...

(Jigarbov 16:56, 28 September 2012 (UTC))

[!!] I can't create a world. User:ILeon/Sig

  • Me neither, gets stuck on "Generating terrain". After restarting minecraft, world appears in selection screen, but when opening MC crashes again. Log:
--GALAKTOSTalk – Win8RPx64, Java7u7x64, NVIDIA GeForce GTX 560 14:55, 28 September 2012 (UTC)
  • Confirmed for Default and Large Biomes world types. Superflat seems to be working normally. --X- 24:30, 28 september 2012 (UTC)
  • When I fly on an already generated world into new terrain, I get disconnected with an "Internal Server Error"; I'm pretty sure it's the same bug.
(I think the names in square brackets in the stack trace are MCPatcher's deobfuscations, but don't worry, the jar was vanilla) --GALAKTOSTalk – Win8RPx64, Java7u7x64, NVIDIA GeForce GTX 560 15:10, 28 September 2012 (UTC)
-- ~reptile311 (Win 7 64 Java 7u7 i7 2GHz 8GB): I've created a new world in a fresh installed minecraft 1.3.2 with minecraft.jar (12w39b) and minecraft stopped in the world generation screen with the following error (It's the first snapshot, that do not at all works for me.)
---Haxer, Same problem

[!!] Minecraft Server running on CentOS crashed while loading new chunks. Both crashes happened within minutes of restarting the server. Included both crash reports for reference. When trying to downgrade back to 12w39a world remains unstable, server doesn't recognize it crashed but becomes locked up.

going back to 12w38b appears to stabilize things

[!] Memory Leak while running Server on CentOS(linux), Server left up for 24 hours used 1600MB of memory when idle. This has been since at least 12w38b when we first started to use the snapshots. Requires reboot to release memory.


I use the following script to start the server:

#!/bin/sh
 BINDIR=$(dirname "$(readlink -fn "$0")")
 cd "$BINDIR"
 java -Xmx2048M -Xms2048M -jar /home/kheisler
/Desktop/Minecraft/minecraft_server.jar

--MusicPhreak9937 9/29/2012 12:12AM UTC

[!!] macOS Loading Minecraft using the MinecraftLauncher.jar crashes Minecraft on a black screen.

--Dlminecr 10:52, 29 September 2012 (UTC)

[!!] Random crash bug when exploring a ravine. --Keithicus420 18:27, 29 September 2012 (UTC)

[!!] [SSP] Disconnected from server: Internal server error while playing SSP. Sun was just going down, probably had just hit the horizon is the only significant thing happening. Map was generated with 12w39a Used a map generated in 12w39a and same problem in map from 1.3 that was converted. Unable to generate a new map at all, gave up after waiting 10 minutes.

-Porrohman

[!!] [SSP] Same circumstances as above, but in 12w39b. The server kicked me for "Internal Server Error" and then clicking to return to the main menu crashed it.

LB(T|C) 03:16, 30 September 2012 (UTC)

[!!] In 12w39b, When I attempt to "zoom out" a map multiple times without closing the crafting GUI, minecraft crashes with the following error report --Crazyape95 00:24, 1 October 2012 (UTC)


Annoyances


Fixed/skipped

Gameplay

Bugs

[!] [SP] While playing skyblock. Water that flows into the void causes major lag --BUcKeT777 04:58, 29 September 2012 (UTC)

[X] There is no flag that makes it so that mobs can't breathe in lava. Particularly noticeable with Fire Resistance or Zombie Pigmen. A bug as old as lava itself. TorchicBlaziken 22:12, 28 September 2012 (UTC)

[X] If you use the command "spawnpoint X #over128 Z then activate it then kill yourself it does not spawn you there. It says that your home bed was missing or obstructed. I tried having a platform where my cords where but it still didn't work.

Intended feature

[X] Ever since 1.3, player Score is bugged and doesn't work at all. It's supposed to go up when you gain experience, and did so in 1.0, 1.1, and 1.2, but it does not work anymore, always staying at 0. TorchicBlaziken 18:11, 29 September 2012 (UTC)

Then if it is a 1.3 bug post it in 1.3 bugs, dont you think?

  • No. All bugs that occur on the current snapshot are to be posted on this page, regardless of in which version they were introduced. --GALAKTOSTalk – Win8RPx64, Java7u7x64, NVIDIA GeForce GTX 560 09:46, 30 September 2012 (UTC)

[!] I reported this a few snapshots back to the regular forums. I just did this a few minutes ago in 12w39b so it's still happening. There is a major bug with maps and copying them. Copying one map is fine. Copying a pile of maps works fine but the two piles do not stack if you do it that way. There is also a DUPLICATION bug when ENLARGING maps. If you take a stack of maps that you copied and put blank papers around it to enlarge one, it actually enlarges ALL of the maps in the pile but only takes ONE. So, if you have a stack of 4 maps [1] and try to enlarge with papers,[2] you will get a stack of 3 of the original maps left in the center of the crafting table but 4 (or whatever number of maps you put in the crafting table originally) newly enlarged maps in the creation spot instead of one.[3] They are real maps, it's not a ghost image.[4] I have done this many times, logged in and out, etc. Pashta 04:31, 29 September 2012 (UTC)


[!] Linux+Windows Minecraft does not always register keys being released. That causes player to keep moving in the direction the key was pressed. Also Minecraft window sometimes loses focus after placing and saving a sign. It occurs the more often the slower the computer running minecraft is. This bug has been around at least since 1.3.x 89.75.162.72 09:31, 30 September 2012 (UTC)

[X] Linux When clicking, system cursor appears for a split second. 89.75.162.72 09:33, 30 September 2012 (UTC)

[X] Linux Boats float in midair above the water and/or sink below the water after placing a boat in the water, saving the map, opening the map, and then touching the boat. To reproduce: 1) Place boat in water; 2) Save the map; 3) Open up the same map; 4) You will see the boat floating in midair just above the water; 5) Nudge the boat slightly by going adjacent to it and it will drop into the water; 6) After dropping into the water, it will actually start to fill with water and sink slowly; 7) Go next to it and the boat will float to the top once again; 8) After that, it may start to sink again; 9) This occurs when placed in water in an enclosed dock, and sometimes in open water.

--Eugeniusz 10:02, 01 October 2012 (CEST)

[X] It's still extremely laggy, sounds/damage/etc. take about 3 seconds to catch up at some points. This is on single player. --MFINN23

Annoyances

[A] "Snapshop 12W39A" While on pig (Riding), travel through portal does not work --Psyscicyclic 18:27, 28 September 2012 (UTC)

Is it still an issue in 12w39b? If not, wrong page.

[A!] I don't know about anyone else but, The Nether seems more laggy than ever! Tyzoe98 2:00 PM EST September 29, 2012.

  • Annoyances go in the annoyance section. :p --Keithicus420 18:30, 29 September 2012 (UTC)



Fixed/skipped

Blocks

Bugs

[!] When a player looks at an item frame, mobs start to glitch into and through wooden plank blocks and suffocate. The mobs don't need to be nearby and the item frame doesn't have to be visible but can be hidden behind opaque blocks as long as it is within the field of view of the player. This bug exists since 12w34a. --Obi-Wahn 10:44, 29 September 2012 (UTC). Edit: This does not occur on my Mac. May be limited to Windows. User:ken_garmany 3:45, September 2012

Annoyances

[A] [MP] Sign text cannot be seen if the sign was placed before connecting. Edit: It appears this only happens sometimes. –nyuszika7h (talk) 19:58, 28 September 2012 (UTC)

Fixed/skipped

Items

Bugs

[!] I consider this a major bug because I spent a lot of time finding and obtaining these items. As of 12w39b, all of my carrot and potato items completely disappeared. This affected Potato, Carrot, Poison Potato, Golden Carrot, and Carrot on a Stick... In addition a storage minecart that included these items also completely disappeared. Night vision and Invisibility potions also disappeared. Can anyone else confirm this happened to them, or expand on explaining the issue.

  • This affects inventory items and crops that were planted before 12w39b.

Annoyances

[A] [SP] Consuming Enchanted Golden Apples sometimes consumes two Enchanted golden apples, unless another item is selected. (DXUltimate 09:26, 29 September 2012 (UTC))

Actually this happens to me with any kind of food. -Obi-Wahn 10:52, 29 September 2012 (UTC)
I think it might have to do with the the fact the game is now its own server because when they did that the food issue started. Pashta 02:19, 30 September 2012 (UTC)

Fixed/skipped

World generator

Bugs

[X] In the snapshot 12w39b the nether won't generate for new worlds and the screen will just say generating land and old worlds(with nether already generated) won't load new chunks or update chunks.

[!!] New worlds can't be generated. Waited 20 minutes, which is beyond excessive. Tried random and known good seeds. Monitoring the process shows no activity, then 2%-3% CPU usage spikes every 30 seconds or so. Have to end process, crash file has a time stamp of when the generation started-Porrohman

  • Doesn't happen to me in suprflat, but I believe you with your crash. Pokechu22 23:17, 30 September 2012 (UTC)
  • Superflat doesn't really generate anything other than bedrock/rock/dirt so that's not a surprise. Tried again on a completely different comupter, with a fresh windows install,brand new up to date java and find the same problem. -Porrohman
* Also observed on existing SMP world after more than a day of uptime, no obvious method to recreate. My SMP world has existed since 1.2, upgrading through most snapshots, so this is not isolated to new worlds. --Inertia 01:26, 1 October 2012 (UTC)

Annoyances

[A] [SSP] [CUS] Spider Mine Generation (Abandoned Mine Shafts) on older maps appear to be generated though each other. Only happens on maps generated though versions 1.2.5 beforehand, on newly explored areas. (DXUltimate 09:34, 29 September 2012 (UTC))

  • What does this have to deal with custom maps?Pokechu22 23:19, 30 September 2012 (UTC)

Fixed/skipped

Mobs/NPCs/animals

Bugs

[X] Bats can spawn in the mushroom island biome (tested in superflat world with mushroom island as biome)

Every passive mob can spawn on mushroom island biome, if the condtions are right

[X] Cave spiders can move through solid blocks. I have a cave spider water elevator that I sealed off completely and left one airspace at the top. When I am standing on top of it and facing it, the spiders all pile up in the airspace, and all is ok. The moment I turn around, all the spiders are outside and attacking me. In previous versions this was just a visual glitch, but the spiders were still in the airspace, now they have moved through solid blocks. --BeansAndPixels 16:24, 28 September 2012 (UTC)

Were those solid blocks wooden planks? If so, I bet you were looking in the direction of an item frame when you turned around. --Obi-Wahn 16:52, 29 September 2012 (UTC)
They were wooden planks, and changing the system into stone fixed the problem. It's still a bug I guess, they are not meant to glitch trough wood. Thanks for the tip. --BeansAndPixels 15:01, 30 September 2012 (UTC)

[!] Tamed wolves and ocelots would randomly teleport to you even after told to sit. Has been a bug since the 1.2 update, even more buggy now as they teleport even when you're in the same chunk as them, when before it only happen if they were in an unloaded chunk. --Dorkster 19:18, 28 September 2012 (UTC)

Wrong page, post it in the 1.3.2 issues page, not here
The point is the bug gets even more buggy in the snapshot. --Dorkster 06:14, 30 September 2012 (UTC)

[X] Sometimes tamed wolves (or possibly other mobs as well) would sink into the ground and get suffocated until they die. --Dorkster 19:18, 28 September 2012 (UTC)

Turns out it's the Item Frame and Wooden Plank blocks bug. --Dorkster 06:14, 30 September 2012 (UTC)

[X] The AI defaults to considering Cobblestone Walls as normal blocks. As such, when mobs attempt to path beyond them, they may path through them. This is significantly noticeable with Villagers. If a Villager attempts to path to a house or elsewhere when a cobblestone wall blocks this path, they will run into the wall, attempting to jump over it, and not repath around it. This is incredibly troublesome in cases where cobblestone walls attach to sides of houses - a Villager can become trapped against the Cobblestone Wall throughout the night and likely killed by a Zombie, since the AI believes it is still taking a valid path to the door. I've also just noticed Iron Golems having the same problem, not to say this isn't universal. --MegaScience 15:57, 20 September 2012 (UTC)

This bug is still prevalent in 12w39b. This will be troublesome if it makes it to full release - I'm sure mapmakers will incorporate cobblestone walls in villages, and discover all the villagers die because they get stuck against the walls all night. --MegaScience 23:39, 28 September 2012 (UTC)

[X] the witch mob in 12w39a is not fully jointed and looks like the steve texture was copyed over the old one 60.241.149.235 03:46, 29 September 2012 (UTC)

[X] There is still a GL Error with the Witch texture, causing it to show white. This problem still exists for some (including me) since 12w39b. --SN777_Divinus 23:01, 29 September 2012 (UTC)

I found the problem of the bug. Originally, the Witch texture image is 64x126. At some point, it was fixed to 64x128. While updating my texture pack, I did not observe this change until recently. Sorry for the misleading. SN777_Divinus 07:06, 01 October 2012 (UTC)

[X] Not sure if this is intended but pigs no longer can be herded with wheat. --MFINN23

  • Intended. You need carrots since 12w36a. --☺ Sven ? ! 08:02, 30 September 2012 (UTC)

Annoyances

[A] The Night Vision potion effect currently has no effect on mobs. TorchicBlaziken 15:28, 30 September 2012 (UTC)

  • Of course, what effect should night vision have on mobs? They can already see everything regardless of the light level. --☺ Sven ? ! 16:16, 30 September 2012 (UTC)

Fixed/skipped

Graphical/lighting

Bugs

[!] Ever since the 1.8 lighting update, my lighting has been seriously messed up, especially at night. During the day, lighting is normal. However, at night, the lighting changes drastically. To describe it, it seems that the light limits have been reversed. At the surface, it's still tied to a sun light level, that is, the surface is lit up like sunlight, even though the sky is black and starry. And for caves, the lighting is restricted to moonlight, but still has gradation, as in, there are 16 notable values. This seriously breaks gameplay at night, as you can't see anything in caves without a good bit of lighting. It also breaks light beacons on the surface. I have no idea how this got by, as it seems like a glaring mistake; maybe you can figure it out! Note: This only seems to apply to actual blocks; entities are darkening as they are supposed to. --Wormy14 12:42, 30 September 2012 (UTC)

Doesn't happen to me, what kind of computer do you have?Pokechu22 23:23, 30 September 2012 (UTC)

[X] Farmland exhibits very dark lighting in the sunlight, version 12w39a. Not sure if this was fixed in 12w39b, didn't see it mentioned as a bug yet.[5] Win7SP1x64 Java 7u7x64, NVIDIA GeForce 610M --CapSAR273 14:37, 29 September 2012 (UTC)

It was fixed in 12w39b, but you have to wait for or force a lighting update. --Obi-Wahn 17:05, 29 September 2012 (UTC)

[X] Pistons will not let any light through while closed, they will let some light through when open (as shown in Dinnerbone's twitter screenshot), and they will let full light through while closing, which looks really bad. --GALAKTOSTalk – Win8RPx64, Java7u7x64, NVIDIA GeForce GTX 560 14:57, 28 September 2012 (UTC)

  • The full light thing has been in the game for a while, but it is annoying. Also, pistons don't let light through the base, only through the head. Pokechu22 23:25, 30 September 2012 (UTC)

[X] The combination upside-down slab next to normal slab lets light pass.

File:2012-09-27 18.32.24.png

A slab floating in the air half a block above the ground, beside a slab on the ground lets through light.

  • No, sir, I am 100% sure I had smooth lighting on when taking these screenshots. --GALAKTOSTalk – Win8RPx64, Java7u7x64, NVIDIA GeForce GTX 560 13:54, 29 September 2012 (UTC)
  • But it only happened without smooth lightning before. Must be a new bug. --☺ Sven ? ! 14:11, 29 September 2012 (UTC)
  • that bug has been there since ice was implemented, with or without smooth lighning.
  • It happens to me too, when I don't have fancy graphics on -- 03:09, 30 September 2012 (UTC)

And the music sounds like a nightmare when it plays, no missing it with music on there!

Skeleton Continuous noise 12w38+

Skeletons make a continuous aggravating and very loud sound when stuck in water flow, most notably when in caves at the bottom of a pit where a water fall is occurring. Began happening when the new sounds were introduced.

Not the right format for a bug report, but close. Also sign your name with ~~~~. Pokechu22 23:06, 30 September 2012 (UTC)
