Minecraft Wiki talk:Issues/Beta 1.9pre5

Compass
Compass doesn't show right spawn position after I sleep in bed. It shows default spawn point not my bed (home) position.
 * it is supposed to work like that--Gil2455526 18:39, 28 October 2011 (UTC)

The compass points only to the initial spawn point, it doesn't point to the last sleeped bed. It always was like that.

Coal drop
When I mine coal ore it only drops one coal instead of 4-5 that it used to Strange, because I've never installed any mods. I play on two different computers and on both of them I've had 4-5 of them. O.K. leave it. My bad probably.
 * Dropping 4-5 coals from one block is feature of the mod you have installed (which is compatible only with specific Minecraft version). Minecraft always drops 1 coal from 1 coal block.--Metalim 12:34, 28 October 2011 (UTC)

Pig Booster?
There is a very old booster bug that still works. Get a pig in a minecart, put a saddle on the pig, nudge the cart so it's moving in the direction you want to go and then hop on the pig to travel forever. There is an example here: --AISim 20:41, 27 October 2011 (UTC)
 * If you place about 3/4 minecarts in the exact same place, you can repeat this. (Confirmed 1.8.1) Cool12309(Talk 00:32, 28 October 2011 (UTC)

Non-pre-release bugs?
There's a feature freeze, and the implication is they're now attempting to squash as many bugs before the 'official' release of Minecraft as they can. Jeb HAS FIXED bugs that exist outside of the pre-release cycle (e.g. break a block with the last hit on a tool and you don't get the block is now fixed). However, most of the fixes seem to come from the pre-release pages. I can't help but get the impression that the assumption is that the preX bugs are the only few ones that exist, even though many of the bugs on the bugs page exist in the pre-releases as well. Should we be listing other bugs on these pre-release pages? Or instead of listing ALL bugs individually, maybe we can put a link at the top that simply says something like "All bugs in 1.8" with a link to the bugs page? Moleculor 17:40, 27 October 2011 (UTC)


 * I think that if you can reproduce the bug in this pre-release, it should be added to the list. My .02
 * I've had reproducible bugs removed from the 1.9pre lists "because it was in 1.8". I'm thinking that was a decision that was made before we knew Jeb/Notch would be focusing on these pre lists. Moleculor 03:24, 28 October 2011 (UTC)
 * Moleculor, this had been the case, and I supported the decision at the time. Now, however, I would agree that all bugs should be listed, regardless of whether they were in a previous full version. — minrice2099 (talk•contribs) 05:15, 28 October 2011 (UTC)

Falling through blocks when walking on/near redstone repeaters
When walking parallel to a repeater, close to the edge, you will sometimes fall through the block you are on. Repeatable.

Also existed in Pre-4. Not sure about earlier than that. Jov_West 24.22.9.124 17:40, 27 October 2011 (UTC)

Confirmed 1.7.3+ Cool12309(Talk 00:33, 28 October 2011 (UTC)

Camera Bug
Jeb just tweeted that he forgot to remove a debug tool. Pressing the F6 key causes the movement to be stuck with the camera, making it possible to walk into blocks. If you walk into a block with the camera, the game will switch to ego-perspective (if you're going in from third-person perspective) an the bedrock-texture appears on the whole screen till you walk out of the blocks. 91.21.83.198 16:02, 27 October 2011 (UTC)Centrophobia

Ahh but that's such a cool debug tool. I love it just like the dupe bug in 1.8 pre-1. Of course this is debug and for developers but hey, we are testing pre-releases why not? About time we have cheat codes >:) Good thing its being removed though. ~DaleK

Hand noclipping
You can hit though blocks and hit an animal in creative mode. I was trying to breed 2 wolves when I had them stuck in a pit. When I dug away some dirt the animal got hit even though it was protected.

I have not tried this in survival/hardcore and this was in SSP


 * thist i a bug that has existed since creative mode was added Quarg 16:15, 27 October 2011 (UTC)

Server Bug
The Client Can Place And Break Blocks 1 Block Further Than The Server Can, So The Blocks Re Appear. This May Of Been In 1.8

Ocean Horizon Glitch
This bug makes the horizon flash when jumping in the ocean or in a boat. You can only see it when there is water on the horizon, not land. I believe it has to do with the lowered sea level and the background texture was never changed. Example
 * it's been like this since 1.8, from what I can tell I think it's because of the boat bobbing so you go from it being at the 'render ocean edge' threshold to the 'don't bother rendereing ocean edge' threshhold Quarg 17:15, 27 October 2011 (UTC)


 * It occurred in the 1.8 update because the water level was lowered one block. Previously, water level was at 65, now its at 64. This is evident when you are in pre 1.8 terrain, and new 1.8+ terrain generates, leaving a seam between bodies of water which are now one block lower than before. When you used to dive into water at level 65, the horizon would turn blue to create that underwater effect. But now when you dive at the new water level, the horizon still behaves as if the water level is still 65, causing that horizon glitch.

Doesn't the view distance in caves get shorter when below ocean height also? Drazong

Water block glitch
When a water block is placed with empty space underneath, a column of source block is created under the water block.
 * I'll confirm this, got the same thing. Could be a feature. Musketeer925 20:37, 27 October 2011 (UTC)

The End

 * When you enter the end all enchanted items have their enchantments removed
 * Maybe an intended feature?


 * On SMP, our portal to The End took us to an empty, single-layer obsidian platform in the middle of nowhere. Instead of (0,y,0), we ended up at (1440-ish, y, 0-ish).
 * Can be (semi-)confirmed by me: http://i.imgur.com/cD6Ku.jpg Drazong (I'm not sure if what shown in the picture is normal or not, I have always spawned on a larger land mass.
 * Image is 403'd. Cannot see it.


 * I see this imgur problem all the time. People claim its a 403 when clicking it.. If you would take the time to remove the "i." at the first part of the link. It would load fine.. :D Try it.. -- Throex  '''TALK 20:00, 27 October 2011 (UTC)

When you enter the End it does not generate terrain. The only thing in the End is the obsidian blocks you spawn on.

Food
I am hungy and can't eat anything, (playing on normal without mods) 82.113.99.49 17:37, 27 October 2011 (UTC)

I am immortal to, I switched from Creative to Survival. Thats the reason for all this

Performance
I observed extremely large fps drop - from more than 90fps to 15-20fps. On pre-4 version even with hd (64x64) texturepack i had better fps than now with default.--Neonidas1 17:50, 27 October 2011 (UTC)
 * edit - it looks that the new world is being generated for much longer. After a few minutes fps rate goes up to 40-45, but it's still much lower than in earlier version --Neonidas1 18:11, 27 October 2011 (UTC)

Pressure plates perma-activated (SP)
This bug was marked unreproducible by Jeb in the pre4 bugs: [U] If a pressure plate is activated when logging in, it will stay activated until you destroy it or quit. Just tested it. It's a SP-only bug. When you quit the world while a pressure plate is active, when you load the world again, the pressure plate will stay activated even when you go off it. It only turns off if you destroy it. Happens with both wooden (items, mobs, Steve) and stone (mobs, Steve) pressure plates.

Memory Deallocation Problems
Since 1.8, at the very least for Windows XP x86, Minecraft thinks it is deallocating memory when it is not: Compare the javaw.exe process (minecraft's instance of java) to minecraft's F3 memory usage. Minecraft almost continuously uses more RAM, never deallocating more than a few hundred KB. This causes javaw.exe to use more and more RAM until the game inevitably crashes. The issue is substantially more noticeable when using high resolution texture packs. //Minecraft just shows up its own memory usage. But external libraries, like LWJGL, Minecraft's Graphics Library, can take more RAM, that won't show up in F3-Stats. Also, java programs cannot deallocate memory. They cannot decide anything about memory-management in JVM. And since there is no support for hires-texture packs, this isn't Mojang's Problem. Give Minecraft more RAM if you use hires-packs. Just google about it - you'll find about that. //Minecraft is running out of ram and crashing on machines that it never used to as of 1.7.3. When Minecraft updated, it broke. Many people are experiencing this issue but don't know how to diagnose it, and it makes the game very difficult to play. Just because you don't experience it doesn't mean it doesn't exist. It worked before and now it doesn't - It can, and should, be fixed.

Fence Gate block are not thin as Fence block
Since "some" update Fence blocks became "thin" as Glass Pane and Iron Bars (why wasn't that mentioned in Versions?), Fence Gate seems was forgotten. {0xE1 20:24, 27 October 2011 (UTC)}

Creative inventory missing and unneeded items list
There are missings and unneeded items in the creative inventory (don't modify that list) :

Missings

18:1 Spruce Tree's Leaves 18:2 Birch Tree's Leaves 18:3 Spruce Tree's Colored Leaves 31:0 Dead Bush placeable on dirt and grass 31:1 Tall grass 31:2 Fern 44:6 Alternate Stone Slab 52:* (Working) Mobs Spawners 60  Farmland 78  Snow Plate 90  Portal 97:0 Silverfish Stone 97:1 Silverfish Cobblestone 97:2 Silverfish Stone Brick 99  Huge Red Mushroom 100  Huge Brown Mushroom 119  End Portal 120  End Portal Frame 263:1 Charcoal 2267  Music Disc C418 - where are we now

Unneeded

83  Sugar Cane Block - There's the "Sugar Canes" item (338) for that 92  Cake Block - There's the "Cake" item (354) for that

In which category of "Known_bugs/Version_1.9pre5" should we add that ? "Gameplay" ?

Hit box in SMP
This bug has been around forever. But the hit box of mobs in SMP only works when you're at the right distance from them. So, if you're right next to a mob, but down a block from it, hitting its legs with a sword will do nothing to the mob at all.

Mobs in water glitch vertically in SMP
This bug has been around for a long time. Mobs moving in water that reach a dead end will glitch vertically up through many blocks, "jumping" and become unhittable by the player. Slimes are the biggest culprit of this vertical glitching bug, but any mob will do it in water.

Animals
Sheeps only spawn without wool on them, I only see naked sheeps and when I kill them I won't get wool, too.

Sometimes cows will run around after being hit and never slow down.

Maybe something is wrong with your minecraft installation or mods cause some trouble, because my sheeps arent naked xD. [2011-10-29]

Chest Sounds?
Chests still don't make noise for me anymore :( --Nebetsu 22:57, 27 October 2011 (UTC)

This occurs in all prereleases because the resources (such as sounds) are not in the .jar-file. Will automatically be fixed with the update, when the resources are downloaded.

Terrain Generator bugs
Holes in the ocean, on surface 1, 2 and in the deep 3

Mushrooms spawn on leaves: 4

Trees can spawn in the air (or maybe the cave beneath it was generated last): 5

(None of them is fake! They are reproducable with the shown seed and coords.) --Modran 00:39, 28 October 2011 (UTC)

I took a world from 1.9pr4 (no mods) and just replaced the minecraft.jar with 1.9pr5. I have found 4 chunks that have ceased to save. I have screen shots from both MCedit and in-game. If I try to edit the chuck to be back to what I had it as (part of a reed farm), it tries to save, fails and respawns a new (different) chunk. (need to upload pics, will link in a minute)

Thirdperson?
Thirdperson won't work in The End. Haven't tested in overworld or hell yet.

Can't edit blocks in (+/-16, *, +/-16)
I can't place or destroy blocks within 16 of (0, *, 0). Update: If I op myself I can create/destroy no problem.
 * It's not only spawn protection, it's been around for many many releases, and is an intended feature. Moleculor 03:27, 28 October 2011 (UTC)
 * Guess I just hadn't tried to edit blocks in the spawn area in previous world generations. Thanks. CeeeKay 07:20, 28 October 2011 (UTC)


 * i cant edit even in singleplayer w/o crash 96.228.144.156 03:15, 29 October 2011 (UTC)

Mobs
I got blown up by a creeper then I started to float and could float into blocks in survival mode.

The Creepers do not blow up when you are next to them. You have to hit them, then they will explode.

Zombies do not attack you when you are next to them.

Skeletons do not attack you when you are next to them.

Blazes do not attack you when you are next to them.
 * uh they changed that mobs ne neutral when in creative mode...--Gil2455526 20:25, 28 October 2011 (UTC)

Breaking ladder block while on ladder
While on a ladder, holding shift to stay still, place a ladder on a nearby wall. Now try to destroy it. The break animations plays, then resets, in a loop as you keep trying to break it. If you aim the cursor higher, the animation completes and the ladder pops off. This is on Ubuntu 11.10 Shjohnson.pi 06:37, 28 October 2011 (UTC)

minecraft_server.exe Not compatible With Windows
So I download from the link Provided by Jeb_ and save it as Minecraft_Server.Exe and whenever I try to Launch minecraft_server.exe a warning message just pops up and says "Version of Program is not compatible with your version of Windows" I'm running Windows 7 Home Premium 64 Bit.

 You seriously renamed the .jar extension to .exe ? =p

Windows built in anti-virus will change it to .zip, so maybe he changed it to .exe not knowing it was supposed to be .jar.

 Well I don't know how to use the .jar, and changing previous versions to .exe has worked.

Blocks
Blocks of iron have a new texture. Might have been intentional?

Lava
Infinite lava/replicating lava sources are now possible: Make a pool one block deep, in the shape of a plus sign (i.e. dig out 5 blocks) and put lava source blocks in all of them. When you now scoop out the middle one, it gets recreated and the 4 outer ones (which will flow for a moment) will turn back to sources, too. Bug or Feature? - 92.227.75.63


 * Good find! It looks like a new feature to me, and I am glad for it. - Jecowa 12:16, 28 October 2011 (UTC)
 * Just a small edit, the pool doesn't have to be one block deep for the bug/feature to work!- gusti123 18:23, 28 October 2011 (GMT+1)

"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." Unlike water, lava won't prevent fall damage. The only way to avoid the fall damage is to find water or ladders. 71.46.222.254 13:20, 28 October 2011 (UTC)

If you place a bucket of lava in a furnace it will disappear when you place iron ore inside. It will continue to smelt the ore until it is finished but will not cook or smelt anything else afterwards. Not confirmed to occur with other furnace contents.


 * From what I remember, a bucket of lava simply smelts everything you put in the furnace (e.g., 64 iron ore, or a pork chop), disappearing when smelting begins.

Clouds change colour depending on character facing
This is especially noticeable at sunrise/sunset, when there is a reddish/orange tint in the sky. Pick a cloud which is roughly at 90 degrees to the sun and moon. Keeping the cloud in your field of view, turn towards the sunrise/sunset. You will see the cloud become more orange/red in tint. Now turn back the other way towards the moon. The same cloud will grow paler and more bluish. Obviously clouds should show different colours depending on their position in the sky. But should they actually change colour as you turn? I don't think so.

Crash entering inventory if Minecraft is started on second monitor
Entering inventory or opening in-game menu crashes 1.9pre5 in OS/X Lion, if Minecraft window was moved to second monitor BEFORE logging in. If you login on main monitor and then move window to second monitor, then it works fine. Monitor configuration is following: https://skitch.com/metalim/greyx/thunderbolt-display --Metalim 12:34, 28 October 2011 (UTC)

Bug when entering blacksmith's house?
Seems to happen when walking between the fencepillars. W7 64 bit, SMP.

Redstone block lighting
Maybe this is an older bug but I noticed that the light emitted from the redstone blocks while mining them is not adding up to the surrounding light. For example, if I have a torch next to the block and start mining it, the block will appear darker than it was before. If I remove the torch, you can see that the block lightens up. So, in numbers, the block emits a light of value 2 (in a scale of 0 to 10), the torch gives off a value of 7, but the result of the light on the block is still 2 instead of 2+7=9.

Skin Drawing Bug
There now seems to be a bug with the skin drawing that causes the bottom of the dead to be drawn 180° out from how it was previously.

Acheivements not working
I just started playing the prerelease 5, and have made a good start, but everytime i log in my acheivements reset. Anyone else tried this?


 * It happens if you just updated the jar, if you're playing offline, or if you're playing on more than one computer. Any of these the case?

Lilypads in Creative Mode
According to the article, lilypads do exist on the Creative mode menu, but... I've got it open right now on the default texture pack (and it is on 1.9pre5, to make sure), and they're not there. 50.98.131.131 18:02, 28 October 2011 (UTC)

Switching from Creative to Survival mode Glitch.
I don't know what this would go under but, if you switching from creative mode to survival using    NBT-edit and save, The game thinks your still in creative when the world is labeled as survival on the save file menu. meaning it is impossible to switch from creative to survival in pre-release 5 this doesn't happen with pre-release 4.
 * There are 4 "abilities" in the level.dat. Maybe setting them all to 0 is the fix? I know setting flying & mayfly to 1 on a survival world will enable flying but still keep the world in survival mode. --KaizenNeko 18:38, 28 October 2011 (UTC)

Citation needed on falling water destroying transparent blocks.
I've brought the question up numerous times in various social media and related discussion places, resulting in the thread being closed, downvoted, answered "This is as intended" and accepted without a source, and when asking for a source, nobody provides. It seems like this is common knowledge/hearsay, but not written down anywhere and nobody knows or is willing to answer where. I refuse to believe that this is not a bug based on someone's word without proof. I'm worried that this is an aberrantly subtle bug that has worked it's way in without notice because I really remember the behavior being different, and heartened the fact that someone ELSE posted about this means I'm not the only one. I seek resolution on this issue.--PlNG 18:34, 28 October 2011 (UTC)

Flying above snow???
I was playing the 1.9pre5 and I wanted to make a Snow Golem. So I put one snow block down, jumped on it, then jumped and put the second down. Then as I was trying to jump to put the pumpkin down, I couldn't jump. I could move left, right, forward, and backwards, but not up and down. So I got out and deleted the world. I made a new world and played it, and I still couldn't come down or up. Help?

Filling water bottles in cauldron bug
When filling water bottles from a cauldron, from a stack, or single, in your 'hotbar', they will dissapear (from sight) from your inventory. If you click e to look, they won't show up, but if you go to a crafting table or a chest, they will suddenly be there, in your inventory. - I tried this with single bottles or a stack, tried shutting down server and client and restarting to make sure I could reproduce it. Tried it from different inventory slots.

Also made a quick video of it at youtube watch?v=YebpDi7Kjrg

Sorry but your bug doesnt work, i tried it in my survival singleplayer map 100% legit no mods no cheats as vanilla as possible and i succesfully filled my bottles with water at the cauldron and they were in my inventory, no bug. [2011-10-29]

Glass Panes do not connect to adjacent doors

 * This has been there since Glass Panes were implemented, and it's really annoying, in that it is possible for mobs to see the player around the side of the door, and creepers to explode through it, and just makes it look bad.

TNT drops item in creative mode.
When destroying TNT in creative mode(not detonating) the TNT item still drops, unlike any other block in creative. Tinaun 03:14, 29 October 2011 (UTC)

I played around with TNT in creative-mode quite a while but i never mind that. I can absolutely confirm that and i also tried a few other things out, but nothing dropped an object. [2011-10-29]


 * That's happened in Beta 1.8 and 1.8.1, too. I don't know whether it's intended or not, but hopefully that doesn't happen (at least I hope) alexkill51 29 October 2011 (UTC)

CPU
Pretty much constant CPU usage for 1.9pre5 client on OpenJDK 6 under Debian Sid, on a Pentium 4 2.8GHz with hyperthreading on, and 1.5 GB RAM with up to 1 GB allocated to Minecraft. Would conclude OpenJDK was at fault except 1.8.1 does not have this problem. For comparison, 1.8.1 has both virtual cores busy (between 50% and 100%) but never constantly maxed. Most of this usage (~95%) is in the "tick" process according to the pie chart when F3 is pressed. FPS around 3-5, making the game unplayable. Have noticed that CPU usage becomes more tenable (~85%) when Escape is pressed and game menu comes up. Let me know if gdb output or stack traces of any kind would be useful. --121.79.226.73 04:36, 29 October 2011 (UTC)

Grass block sides don't have biome shades
Grass blocks all have the 'standard' light green side texture, no matter what color the top of the grass is. Eg: http://imgur.com/cBs2K and very noticeable in a swamp biome.

Redstone-Torches attachable to jukebox
Dont know if someone already tried but you can attach redstone torches to jukeboxes. you can put them to the sides and above of it, maybe intentional? I dont think so but try for yourself, thanks. [2011-10-29]

Cacti AND many other things dont REALLY burn and survive even lava
I know that this information is already in the minecraft wiki but i consider it a bug, although some might argue that its a feature xD. Please add your opinion, thanks. [2011-10-29]

I have to edit this because after some creative-mode experiments i sadly experienced that many things just dont want to burn and as the heading says survive even lava, LONG-TIME xD. Some of the few things that burn are bookshelves, wool, wooden stairs (havent checked the other ones), but also leaves (who could have known!). Things that DONT burn : workbenches, pumpkins, chests, jukeboxes, noteblocks, SNOW-BLOCKS (just put them in lava and see for yourself or use flint and steel, it doesnt work), hatches (aka trap doors) and i bet many other (even wooden) things. If in lava then they sometimes catch fire but arent destroyed. Please respond and post your opinion on this topic, thanks. And i know that somethings in minecraft arent as real as they could be but those little things like objects made of a burning material that catch fire but dont get destroyed are also some kind of bugs, maybe just minor but i put an eye on such things, sorry (from the creator of this topic).

Zombie Pigmen, anthropomorph pigs which are actually half zombie, are invulnerable to fire and can even take a bath in lava without taking damage, i know its already in the mincraft wiki but i just wanted to mention it, sorry again (the creator of this topic). P.S.: I just love minecraft xD.

Tall grass wont catch fire near lava
I already started a topic concerning fire and things that dont burn but this one here is slightly different. Its possible to set tall grass or bushes/shrubs on fire and it will spread if near other shrubs/bushes/tall grass BUT near lava it somehow wont ignite/inflame/catch fire, tested in creative mode. Could need confirmation just to know that im not insane according to my opinion about fire and its property to set things on fire AND destroy things, thanks. [2011-10-29]

Flying low above rails and tall grass in creative-mode
When flying low above rails or tall grass in creative-mode you can hear fast stepping sounds. To recreate that bug fly as low as possible above railtracks or tall grass, really flying not walking or running (its quite obvious that walking or running creates stepping sounds). It doesnt work with dirt or sand, so im not sure if the sand/dirt thing is the bug or the rail/tall grass thing. Please respond, thanks. [2011-10-29]
 * i can confirm this, tho theres another report (Simultaneously jumping and running over rails and tall grass) what is also caused by this.

Im not sure if they are really related to each other, maybe its the same cause maybe not. I also know about the other topic, because i created both, thanks for reply (topic creator).

Creepers spawning in my house
I don't know if it's a bug or something else, but creepers keep spawning in my house, often behind me, blowing everything up, even if it's full of torches and completely closed...

Falcomatto94 12:22, 29 October 2011 (UTC)

Do you have a open or closed roof, because sometimes they also spawned in my house but after i made roof i didnt happened again. Not sure if its related but who knows.

Activation of flying when minecarting in creative-mode
I created a 1km long railtrack for the "On a Rail"-Achievement and while minecarting i pressed space 2-times and the view changed a little bit. That was a bit suspecious so i repeatedly pressed space double times to find out what it is and i believe its the flying-mode. So again for short, its possible to activate flying-mode while minecarting in creative-mode, please try and confirm. Thanks. [2011-10-29]
 * i can confirm change in field of view, but i couldnt get minecart to fly.

Maybe i described it not clear enough but the minecart wasnt supposed to fly, i just meant the change of view, thanks for reply (topic creator).

Simultaneously jumping and running over rails and tall grass
If you run and jump simultaneously over rails or tall grass, you can still hear your stepping sounds (although you are fast jumping, its more obvious when you dring a potion of "Swiftness II" like i did). [2011-10-29]
 * i can confirm step sounds playing while in air, jumping over tall grass. [edit:] theres another report that can tell cause to this (Flying low above rails and tall grass in creative-mode).

Sometimes leaves generate light
After completely enclosing a tree (actually several) I noticed they were still lit. Upon investigating further I discovered that some of the leaf blocks were generating light. This isn't the light update bug where if you place a torch it'll force an update (ie, placed a torch and removed the torch and light remained). I turned off smooth lighting to isolate which blocks were generating the light and when I removed them the light vanished. I noticed also that the light level adjusts depending on the time of day so it's still linked to sunlight.

Here's a pair of images that shows what I'm talking about. This is in creative mode and I haven't tested to see if it does it in normal mode. It makes for a cool aesthetic, but it's a bug and I'd rather not have to go around eliminating all the light producing leaf blocks. --StarkRG 13:32, 29 October 2011 (UTC)

Weird cauldron-bucket-behaviour in creative mode
If you want to fill a cauldron you need a bucket of water, but you cant fill an empty bucket with water. If you try then the water source block disappers but you dont have a waterfilled bucket, its still empty. So you have to take a waterfilled bucket from your creative-mode-inventory, that works. So you right-click to fill the cauldron and your bucket gets empty and your cauldron is filled, WHAT THE HECK?! You end up with an empty bucket in your hotbar XD!!! PLEASE comment, THanks. P.S.: I found out about that bug as i tried to recreate the waterbottle bug. [2011-10-29]
 * keeping bucket from filling in creative is bug fix, so you can easily remove lot of water / lava. but bucket getting empty after filling cauldron, thats bug. i can confirm this.--88.194.187.14 19:11, 29 October 2011 (UTC)

Yeah i know that its normal that an empty bucket stays empty in creative, but its more the overall behaviour. If the bucket is empty it should stay empty, if its filled it should stay filled. The other way would be the normal behaviour, but its something in between. Thanks for reply (topic creator).

Failure to delete world in hardcore mode on player death
Creating a world with the same name as the previous one where the player just died spawns you on the "deleted" world.

Player inventory is empty but the constructions are standing, the chests are full... biomes seem to have changed

.minecraft/saves/[world name]/regions has several .mcr files

Is this a bug? feature?

 * its a bug

[A] animals (graphically) jump through ceiling
description of area:

i have animal pen 9x9x4 (7x7x3 inside space). with 4-6 total animals, sheeps cows. it got 1 block high holes at 2nd block above ground that go all around pen (with exception of corners). and torches at ceiling inside pen.

bug:

animals in pen almost all the time jumps repeatedly through ceiling appearing above the pen. this is graphically true only, meaning animals cant escape the pen.

can anyone confirm this bug?

Slab collaps
When creating a column of same type slabs using a vertical piston(example setup: http://i.imgur.com/54CBb.jpg), if you then place a same type slab on the top slab, all the slabs will collaps down to the bottom. Smithnc07 17:25, 29 October 2011 (UTC)

Sniper Duel achievement bugged, to be more precise unachievable
I have set up a shooting range which is more than 50 meters long so that i know that the skeletons are at least 50 meters away. Then i killed them but no "achievement get" stuff, nothing. So i am pretty sure that this "Sniper Duel"-Achievement is bugged but try for yourself. [2011-10-29] ==>   imgur.com/a/cpSL8

P.S.: I made the shooting range in the desert biome because theres much more light so i can see those bad skeletons better ;)

Debug Screen
(A) The debug screen is annoying, because At very low frame rates the graph(green commonly,but red in some cases) can rise high enough so that it will cover values like the coordinates. Nosterville 18:52, 29 October 2011 (UTC)
 * this has been for long time and i agree its annoying. i can confirm this. --88.194.187.14 19:01, 29 October 2011 (UTC)

Creative mode - infinite water buckets not working on cauldrens
In creative mode, the water buckets automatically refill themselves after use. However, using a water bucket on and empty cauldron does not refill the bucket.

Mob Movement is inefficient. Agree/Disagree?
So thanks to some overnight idling at my mob farm, I awoke to find minecraft had crashed, it had run out of RAM. I filed a bug on that, but that's not the issue. After boosting ram, and checking the map with MCEdit, I found approximately 700 skeletons and 255 spiders residing in my farm trap.

According to the pie chart, 80% of the CPU/calculations is being devoted to moving 1000 monsters. The path is root.tick.level.entities.regular.move. For nearly 1,000 monsters, 700 skeletons of which cannot move (they are in a 1 wide shaft), this is somewhat inefficient and there may be room for tweaking in there.

Thinking about filing this with a ?

Trees not dropping sapplings
I've had to start the SkyBlock level over a few times because the tree does not drop any saplings. I'm not using any mods, and I'm using the default texture pack. Normally this type of tree will drop several saplings. Jecowa 21:02, 29 October 2011 (UTC)

Edit: I just tried again and have gotten 3 saplings from the tree. But the four tries before that, it gave me nothing. - Jecowa 21:09, 29 October 2011 (UTC)

Cacti Farming
Cacti can be farmed by placing a block next to it. I'm not sure if this is intentional or if it is bug. I have only tested this in creative mode. --This is a feature, cacti break when blocks are placed next to them. Yeah. I remembered a little bit after I wrote that.

Worldname field resets on resize of window
On the world creation screen, when you resize the window, any name you entered in the editbox will be reset to the default "New World". Only tested on Ubuntu 11.10 but this will most likely also occur on other os'. 84.195.78.79 22:50, 29 October 2011 (UTC) tranquility486
 * Confirmed. Added it to Gameplay section. Haseo 03:18, 30 October 2011 (UTC)

Sounds
Rain does not always generate the rain sound. I loaded my single player, came above ground, it was raining, but no sounds. I walked around and started to hear rain. Was this because of the biome I was in (no, it wasn't a desert) or other? There was the bug in 1.8 where rain would come through cave and house ceilings, maybe this is related? Need to investigate further. Haseo 23:32, 29 October 2011 (UTC)
