Mobs glitching above fence tops
In SMP, at least, mobs can jump onto the top of a fence, and/or pretend to get out (as seen by clients). If the server keeps running, however, they will return to their pen.

But they can also jump up on the edge of a fence. If the server is stopped with them in the air, they appear to get their location saved as in the air, and on server restart can walk off the fence post out of the pen.

That's the observed behavior: starting up a server, logging on, and seeing mobs turning in circles on top of a fence, and deciding to come down out of the pen. Is this an SMP only bug (as I'm going to mark it on the bug page), or does this reproduce in SSP as well?

 * You are actually describing 3 separate bugs. The first bug is mobs appearing to stand on fences or even walk ouside. This bug is MP only. The second one is animals spawning on the fence when a chunk is loaded. This bug also exists in SP. The third one is mobs chasing tails, so to speak, whenever their y coordinate is not an integer (e.g. when standing on slabs or fences, or even when falling. —Fenhl 08:29, 5 April 2012 (UTC)


 * I believe mob/animal location on server side never gets top on wall or roof or through fence. Bug is probably on client side, caused by mob/animal (client side) physics calculation them pushing each other. That however is NOT confirmed fact. 93.106.38.169 17:28, 7 April 2012 (UTC)


 * This happens non-stop in MP, regardless of connection. Sometimes (very rarely) they do escape.  It's bothersome making my fences two blocks high and still watching all of the animals glitch up and down.  Sometimes they move into the walls or the ground and their coloring becomes very dark.


 * This mainly happens on multiplayer, but skeletons get stuck in walls a lot. Why?

In-game chat links ignore the .info (probably others as well) TLD
It seems the regular expression used to find chat links is: ^(?:(https?)://)?([-\\w_\\.]{2,}\\.[a-z]{2,3})(/\\S*)?$

Because of the {2,3} it ignores .info (and any other top level domain longer than 3 characters).

Recommend extending it to {2,4}. This still excludes a few (very rare) domains like .museum, and .travel... but that seems acceptable. Then again, maybe this has been considered, and four letter domains were also acceptable losses.

Random Crash
I was playing in SMP and minecraft randomly crashed. Crash report:

Void Fog
Controlling last versions I found this report about Void Fog.



It's quiet "rantish" but I can't say all arguments are pointless. Instead of removing them silently I suggest moving questionable reports here and possibly making a clean version.Of course only if there is notable content.This way we don't miss entries from people without proper manner of expression just because their style is bad.We can correct that too, that's the purpose of a wiki. Remember, not all people's first language is english.

Back on topic,as we keep complains about surface dungeons,and this really has been a very controvertible theme, I think it deserves at least a short note under annoyances.Naturally,any perception is personal, so if you mind be free to discuss it.

There's no offense here legitimating a removal. 184.105.146.14
 * I agree.No one's contribution should be rejected without reason.


 * Not that bad, personal and a little too long but it's a reasonable opinion and more important it's not trolling or spamming.These are the only things that should be removed.Any other thing should be improved and discussed.Some registered users seem to manage the wiki a little high-handed.Especially this page's purpose is to get entries from the WHOLE community.And there are much worse things on this site.I'm for making a more 'wiki-like' and objective version.
 * I think void fog and dimming should be in the options for enable/disable. ~DaleK 00:35, 8 April 2012 (UTC)
 * Yeah,this is really a big problem for many players and I see some good arguments mentioned here.If these would be presented in a proper form it could be very conclusive. 93.128.59.12 22:40, 8 April 2012 (UTC)

Moved Spurious Bug Report
! su Game crashes after 'saving chunks' whenever i walk in a certain direction.
 * Moved to the discussion page because it is very vague, extremely spurious, and requires more information. I don't have a problem with this walking in any particular direction...--Mattrition 15:48, 6 April 2012 (UTC)


 * Random 'saving chunks' crashes have been in the game since ever.Often caused by the combination of your PC/OS/Java version.But without further information this isn't helpful. 184.105.146.14

Mobs
a If you attack a passive mob (cow, sheep, pig) (particularly punching them, which doesn't hurt them much and gives you time to see what's happening) it panics and runs in a random direction. That random direction may include directly towards the source of the damage, which often allows you to keep punching it while it 'runs onto your fists'.82.69.54.207 22:08, 5 April 2012 (UTC)
 * If they run randomly of course they are going to sometimes run towards the damage. That's the definition of random! You even explained yourself why they run randomly, they are in a panic. Are you saying it's an annoyance that intended random behavior acts randomly? --Moxxy 14:26, 6 April 2012 (UTC)
 * Think of a random number between 0 and 180 degrees for mob A and another random number between 0 and 360 degrees for mob B. If you arranged the angles so that the damage source was at 270 degrees, we would say that both mobs will flee randomly, but only mob B will sometimes charge lemming-like towards the damage source. Furthermore, once a mob has chosen a direction, it keeps trying to go in that direction until it has moved some certain distance /in spite of taking further damage/, even though extra damage at least ought to re-randomise the direction it flees in. Hence you can get several blows in while it runs onto your fists. That in particular was why I flagged this as a bug - the random element /plus/ the 'keeps going' part.82.69.54.207 14:38, 6 April 2012 (UTC)
 * This isn't a suggestion forum for your ideas. Moved to discussion. --Moxxy 19:10, 6 April 2012 (UTC)
 * Pardon me, in my follow-up, I was attempting to explain to you why I think that bug really is a bug. Which I did by means of an illustration. From a programmer's viewpoint, there are several ways to fix the problem - and, yes, the simplest probably is just to re-randomise the direction an animal tries to flee in every time it takes damage. But that wasn't me putting in a feature request to Mojang, it was me trying to more fully explain my point [mainly to you]! Now you have bent the posting guidelines for bug reporting for a second time by moving the /entire/ complaint from the bug tracker to the discussion rather than leaving the original report plus a link to these follow-up remarks.
 * If there is /consensus/ that a bug or annoyance really isn't one, then moving it or marking it with a strikethrough is fine, but in this case two responsible people disagree, so for now the report should stay on the bug page. Mojang are perfectly at liberty to mark it N when they get round to it. (BTW it was me that recently tweaked the bug reporting guidelines (as listed in 1.2.4, 1.2.5pre and 1.2.5) to address issues like this, so if you take issue with those changes, now might be a good time to raise the matter.) And yes, OK, I did slightly stretch my own limit of 'if follow-up discussions exceed about 10-12 lines' by two lines.)82.69.54.207 20:35, 6 April 2012 (UTC)
 * Just because a solution has been suggested doesn't mean the problem has gone.The Bug should day on the page,possibly solution can be discussed here.-> moved back without the comments 77.11.150.176 21:14, 6 April 2012 (UTC)

Discussion for Annoyance: Animal reaction when set on fire
Discussion for: a If you set animal on fire it will stay there and die. It does not "panic" like when you punch it.
 * I think this sounds more like a bug. NetherrackCreeper 19:52, 4 April 2012 (UTC)
 * Am I allowed to move or upgrade reports or is this the admins' job? --MCKMan
 * Moving/upgrading reports can be done by any user. I would consider this more of an annoyance as they only run from player damage and fire isn't player damage. So technically they are doing exactly what they are supposed to do. --Moxxy 21:31, 5 April 2012 (UTC)
 * No, should be upgraded to bug, because it's a bug. Specifically, it's a coding omission; passive mobs should attempt to flee in panic from /any/ source of damage.82.69.54.207 22:08, 5 April 2012 (UTC)
 * That had been discussed a while ago.Bugs aren't just technical.They forget to add this behavior to be caused by any kind of damage.So it's kind of bug in the concept of the game. 184.105.146.17
 * We can't prove that they forgot to add this. In these cases we give the benefit of a doubt to the person making the game. --Moxxy 19:16, 6 April 2012 (UTC)
 * I think we can assume that jeb don't intend to make animal flee from player damage but not from fire.He clearly preferred it this way for easier and faster implantation. 77.11.150.176 20:59, 6 April 2012 (UTC)

Discussion For "Crash When Opening Texture Pack Folder"
Discussion for: undefined? Opening the texture packs from the main menu is fine, but when you press the "Open texture pack folder" crashes Minecraft. 64-bit Windows 7 with Nvidia GeForce GT 540, 8 gigabytes of ram, and Java 6/7 (I don't know, but I've tried this on both. Has been a problem since 1.1). This should not be a problem and it is a pain to go into AppData every time I want a new texture pack.
 * Could not reproduce on 64-bit Windows 7, integrated chip, 4gb ram. Has not been a problem for me, and I have not seen other related bug reports. Check to see that the texture pack folder, or some root of it, hasn't been renamed or hidden on your machine. GhengopelALPHA
 * Not a problem for me, either (linux). Sounds like a localized problem. --Mattrition 15:47, 6 April 2012 (UTC)
 * It still doesn't work after uninstalling Java and Minecraft. I'm not the only one that has this problem and I'm not sure what it is. I also tried on the browser from minecraft.net and that crashed too. Also, I'm not sure if this matters but my .minecraft is in C:\Users\*user*\AppData\Roaming\.minecraft
 * From a command line window, run the command "path\to\minecraft\exe\minecraft.exe > output.txt". Reproduce your crash, close the program, and then copy the text from the file "output.txt" into this discussion. I've moved the discussion to the talk page so that we don't clutter the bug list. --Mattrition 21:56, 6 April 2012 (UTC)
 * Well, see, problem is that it just freezes, it's not a crash. So I don't get an error message (yet). The real problem though is that I went to check back at the 1.2.3 where I first found someone had this problem, and it said that it was fixed. Oh, but Mojang, it wasn't. Like I was saying, it freezes and doesn't crash (when I try to right-click and close it, it says Java SE blabla is not responding). I can't tell if it is a Java problem or Minecraft. Also, I don't have antivirus software, so the only thing blocking it would be my firewall??
 * When the program freezes like that an exception is most likely thrown by java. AFAIK you can only see that exception by running it from the command line and redirecting the output to a file. Could you please follow my instructions in my previous comment and paste the result here? --Mattrition 22:42, 6 April 2012 (UTC)
 * Does it work with a batch file? That's what I did and it worked to run with Minecraft.exe. Or do I have to use minecraft.jar?
 * With a batch file just execute "path/to/batch/batchfilename.bat > output.txt" and you should still get something in the text file after you've closed minecraft. --Mattrition 09:24, 7 April 2012 (UTC)
 * Could you send me some sort of confirmed way (with C:, users, etc)?
 * I might have misunderstood you. In your batch file just put "> output.txt" at the end of the command and then run the batch file. --Mattrition 20:21, 7 April 2012 (UTC)
 * Got the error log:

 * I can confirm that this is a video card issue. My laptop runs Windows 7 64 bit and has an Nvidia Geforce videocard (dedicated) and would freeze whenever I clicked the "Open Texture Packs" button while I was accelerating the graphics. As soon as I turned it off the video card and clicked the button, the folder opened right up. --TWP


 * Work around (for windows7 users): Pin explorer to taskbar, then pin texturepacks folder to explorer quick list.

1. Launch explorer

2. Right click explorer that is on taskbar

3. Choose pin this program to taskbar

4. Write  to explorer address bar

5. Drag  folder over explorer in taskbar

now you can go texturepacks folder by right clicking explorer icon on taskbar and choosing texturepacks. 194.215.127.254 10:08, 7 May 2012 (UTC)

Piston Block Being Deleted
! This is kind of hard to explain so I will accompany this with some pictures. Basically when you grow a jungle tree and at the same time it grows you have a piston push the tree over, the leaves of the tree that grow destroy any pistons they come in to contact with.

Here are some pictures to better explain it.

As you can see from the pictures there are only 4 out of the 6 pistons left.
 * I don't think this is an issue specific to pistons. See if you can get freshly grown leaves to replace other blocks such as dirt and stone.--Mattrition 10:13, 7 April 2012 (UTC)
 * Yea this is just an issue with pistons and the jungle trees. None of the other trees do this and only pistons get deleted, I have tested it with other blocks to make sure.You don't even have to extend the piston and it will be deleted.--Datsun80 14:10, 7 April 2012 (UTC)
 * This could happen because before the piston is fully extended it's not a block but an entity which can be overwritten with a block. 77.183.254.38
 * Leaves overwrite any transparent blocks, but not opaque. When a piston extends into you with no other air blocks for you to breathe, you do not suffocate. Therefore, pistons are transparent and can be overwritten by leaves.
 * AFAIK this had been fixed in beta.So it's specific to pistons or this error has returned. 93.128.59.12 22:34, 8 April 2012 (UTC)
 * It also replaces the pistons when they are not extended.--Datsun80 17:10, 10 April 2012 (UTC)
 * Pistons general are transparent blocks, not just if extended 217.50.90.30 20:26, 10 April 2012 (UTC)
 * Could this be considered a reportable bug? I'm not really sure, since it's not clear to me what leaves should be doing. --Mattrition 00:53, 8 April 2012 (UTC)
 * Yes this is a reportable bug. Leaves should not be overwriting blocks. This is very specific to only jungle leaves and pistons, I have tested all the other blocks and they do not get replaced.--Datsun80 17:10, 10 April 2012 (UTC)
 * Someone else has to test this (I'll get to it if I have time). To be blunt. I don't believe you. Leaves are the same block, just with different values. So they shouldn't have different properties. --Moxxy 22:35, 16 April 2012 (UTC)
 * I've got similar problem with oak tree branches. -- pet_cz, 20 April 2012

Creative selection
The creative pick block is buggy, where you click stone you get cobble, you click glowstone, you get dust, you click lapisblock, you get inc sac. Those need to be fixed, but clicking portal blocks, spawners, ice, etc should stay in the game, so that you can still use them. If not, people will just make mods for it.
 * I've added your information to the list of "pick block" bugs here --Mattrition 00:51, 8 April 2012 (UTC)


 * When using the pick block on upside down half slabs (I've only tested stone brick half slabs) it will give you a normal looking half slab which when placed will only appear on the top half of a block. I don't think this was intended because it is not possible to make a full block with two of these half slabs.Sebperth 08:43, 10 April 2012 (UTC)


 * Basically, it gives you the block you would get in survival, which is logical.24.113.34.60 20:34, 10 June 2012 (UTC)

Folder based texture packs not showing logo and describtion
Folder based texture pack(not .zip texture just plain folder) doesn't show the pack logo/icon(pack.png) and the describtion/info(pack.txt). it show the default minecraft texture logo/icon and describtion/info instead. Please test and report!
 * I can confirm this. - roopn

Nether Framerate and Memory Issues.
I went to the Nether and had serious framerate issues on tiny render distance, and all graphical options set to minimum. SOmetimes the framerate was smooth, other times it would fall to 1fps or less. The normal world is fine to play on, no FPS issues whatsoever. But in the Nether its been so bad that I have received an "out of Memory" error and a crash.

Does anyone else have this issue? --Mattrition 09:21, 12 April 2012 (UTC)

I have this fairly often in the overworld despite the fact that my computer has 6GB RAM and a dual-core processor. The Nether's even worse. --King Starscream 20:21, 16 April 2012 (UTC)


 * I have same issue in Multiplayer, never checked in single with this patch though, when I move to the Nether, my FPS goes down to 1 for like 20 seconds, which usually is enough for randomally agressive pigmen to kill me. 87.205.94.189 09:59, 6 May 2012 (UTC)

Colored text on signs not visible in certain angles
a  Some Apple computers can't actually see colored signs, it will only be visible when the player faces at an extreme angle. It appears to happen to Apple computers that have the Intel 3000 graphics.

redstone lamps with silk touch

Powered Railed Vanishes
First time submitter here.

Only creating ONE portal exit in the nether
a The first portal made in the overworld will spawn a portal in the nether as intended but subsequent portals WILL NOT. Any new portals made in the overworld will link to the first portal that Minecraft considered being the "closest" and will not spawn a portal regardless if it should have.

What that means is if you make a new portal in the nether, it WILL spawn new portal in the overworld in the appropriate coordinates. Also if you made a new portal in the nether with the appropriate coordinates to an existing portal in the overworld they will link up and function properly. (Example: I made a portal in my base that kept taking me to the communal portal exit in the nether. When I built a portal in the nether where my base's portal should have spawned, they link properly.)

If this can be verified by someone other than myself, I'll move it to the official list. -- KaizenNeko  ( T &#124; C )  19:34, 25 April 2012 (UTC)
 * Update, this also happens in Single Player with pure vanilla MC.
 * NOTE: I'm posting to the 12w17a buglist as it's present there as well. [[File:Icon-KaizenNeko.png]] KaizenNeko ( T &#124; C )
 * Welp. It's not a bug. Linkage Between Overworld and Nether. Thanks to Mattrition for setting the record straight.

Animal Breeding
Animals are able to breed when in breeding mode, even when separated by up to 8 blocks, and never come in physical contact. It seems like this is not intended behavior.

View turns randomly in minecarts.
While riding a minecart the view randomly rotates slightly left or right, usually left. Very annoying as it makes it impossible to record minecart timelapses.

Unable to collect dropped items
[A!] [MP] On multiplayer, sometimes you are unable to collect dropped items, no matter what it is. (Unconfirmed conditions)

Right Clicking Problem
Tested in survival and creative, only seen in survival.

I am having an issue with placing or using objects and items via right clicking. Examples include (but are not limited to) - torches: if I place one and the mouse moves even a tiny bit, or sometimes not at all, another will be placed on the nearest adjacent surface to the crosshairs - water form a bucket: (dangerous when mining in unknown territory!) if I try to place the source block (whether directly on a solid surface or adjacent to a vertical surface) it will often, increasingly so, place the source block for a split second then pick it right back up before it even has time to flow anywhere - placing blocks: if there is adequate space in front of me, and I attempt to place a block on a vertical surface level with the player's head, it will often throw another one right on top of that (as if it were stacking them horizontally).

Most of these are just annoyances, though like I mentioned, the placing of the water may screw me over if I'm not careful enough. Has anyone else seen anything like this? I took a look around the known bugs page through the bugs and annoyances (and used the find feature of my browser to check out every instance of "right click") and found nothing pertaining to this.

This is not an issue I can produce directly upon command, but it happens often enough to be right about on command.

I have played around with it trying to figure out what may be causing the issue and have, at times, literally just tapped the right mouse button (as in, I start with my finger off of the mouse, and end with my finger off of the mouse. Literally only pressed for a split second) and have still gotten the double-click effect. I feel it is most prominent with placing water.

Windows 7, 4GB RAM, not sure exactly what my video card is but its only a laptop video card. I know for sure it isn't Nvidia, probably some sort of intel(R) card. Just bought a new mouse today and still getting the issue. Vanilla. If any more specs would be helpful please let me know in a comment and I will try to get it to you.

67.242.115.105 01:06, 3 May 2012 (UTC)

I have the same problem and I am also using a laptop. My husband does not have it and he is on a powerful desktop. He thinks it may be due to the strain on my system which, although I can play all aspects of the game is stretched to its limit.

I also seem to have the same problem as that stated above, but I notice it most prominently when placing blocks around a large number of wooden stairs (as in during the construction of a roof). The game appears to lag for a split-second before duplicating the block (putting down two blocks of the type I am currently holding). This also occurs when I break blocks. Note that this is in CREATIVE. So, the problem occurs in both Survival and Creative mode.

67.0.176.233 05:29, 2 June 2012 (UTC)

The problem is not caused by the mouse, it persists if the "Attack" and "Use Item" controls are assigned to keyboard keys, and the mouse is not touched while placing or destoying blocks. This annoyance makes building a pain. Playing with the options does not help. Does anyone know a workarround (mod ?) for this?

Beds resetting weather counter
Just checking, is the fact that beds reset the weather counter considered, by Mojang, a bug? The beta 1.5 patch notes on this wiki state that it is a bug, while I'm not particularly sure considering that was over a year ago and it's pretty minor (so should have been an easy fix).

Overexpanding scanner
a The scanner in the botton left of the F3 screen took over the whole left half of the screen. Every time i look at the F3 screen it gradually creeps forward. It covers biome info, the seed and xyz cordinates! This in Vanilla minecraft. It does this on the browser too. I want to make videos, but I can't make them with the scanner blocking my way! I posted this on the bug page, but I came back later and it was gone. Not downgraded or moved. I looked everywhere.

That's due to low performance. You can hide the graph by pressing Shift+F3 instead of F3.

Thank you for the advice. No scanner, no problem:)-Aezex

It's not a bug it is an annoyance 24.111.30.171 00:45, 9 August 2012 (UTC)

Reporting older bugs
I encountered a bug that seems to be reported for version 1.2.4. Should it be reproduced here or can I presume that it is tracked by Mojang. If I add comments, do I edit on this page or the 1.2.4 page? (If you know the answer, please consider editing the preamble; speaking of which -- wouldn't it be easier if the preamble was a template?)

Tamed wolfs' teleportation glitch
This bug is only on MP. I tame a wolf, then make him sit. When i warp to somewhere else,sometimes, it warps with me too even if it is sitted. Is this normal or a glitch? Can you fix it please?
 * I am having a similar problem on my Survival Multiplayer Server. Sometimes, some or all of my tamed animals (including cats) will teleport to me, even if they were previously sitting, when I log in. This can be short distances (maybe about 1-100 blocks) or long distances (300+ blocks). 71.194.250.72 16:25, 31 July 2012 (UTC)CumpyLustard

minecraft will not connect to on-line
Whenever I try to sign in the game says it cannot connect and I have to play off-line. What am I doing wrong? I have to go to the minecraft site and play in browser mode in order to update minecraft. Is there any way to fix this? I have already tried redownload to replace the file and it did not work.


 * Have you tried emptying your entire AppData folder? C:\Users\<YOURACCOUNT\AppData\Roaming\.minecraft (Note that the AppData folder is hidden.) Minecraft.exe opens Minecraft.jar from there.

Redstone torch staying powered
As far as i've seen, this bug is only in MP. (this is my first post, please go easy). I've built a sand-based tree harvester (see link: www.youtube(dot)com/watch?v=ibuL0p-980E, there is a downloadable map for those who want to test) The first bug is that the sand wont retract. I've narrowed it down to one torch in particular, but its power state doesnt toggle after the player steps off the pressure plate.

Floating Mushrooms?
I started a new world in creative mode with a seed that spawned me in a mushroom biome (614119090021688218), and I explored until I found a lake five blocks deep with mushrooms floating over the middle at the same height as the blocks on either side. No idea what's going on.

Creative Milk Buckets?
undefined ? cr In creative, using an empty bucket on lava or water takes up that lava or water. I know this is intended behavior and is often quite useful. What I think may be a bug (not quite sure) is when you use an empty bucket on a cow. It gives you a bucket filled with milk. Is this intended, or is it a bug?


 * Why would you be milking a cow in creative?  -BaconTaco


 * That is clearly intended. You are MILKING a cow hence the MILK.

Alright,alright, I'm not an idiot. I just thought it weird that buckets stay empty for water and lava but not milk. Are you going to execute me now?

I'm not sure if this should go here, but if it's that bad, mess with your anti-virus so it thinks the bot IS a virus and auto-deletes. Then delete it yourself if it doesn't. And try using a secure delete from McAfee. --24.15.167.216 18:08, 4 June 2012 (UTC)

Boat issue analysis
From what I can see, the bugs that cause the player to take damage either from landing the boat or touching a mob while sailing seems to be from fall damage being applied while in a boat. This could have something to do with how fluids don't restrict movement in creative anymore. Can anyone investigate and/or confirm this? --King Starscream 15:31, 22 May 2012 (UTC)

Redstone Lamps lighting bug
The area around a number of Redstone Lamps I've placed does not light up properly. Rather, it has an unusual shadow covering it as though the light won't load. This is not just a visual rendering problem: the light level drops to 0 when the area is dark. When moving near a dark area, it lights up properly and the light level rises to what it should be. However, when I stay away long enough it darkens up again.

Screenshots here: http://imgur.com/a/XDOl0

It seems only the areas with Redstone Lamps that are placed directly above water level are affected. I had thought it was because the Redstone Torch powering the Redstone Lamp was directly above water, but closing up the area beneath it did not work.

bad graphics card drivers
undefined. Whenever I try to update my minecraft beyond 1.0.0, it tells me that I have bad graphics card drivers that do not support OpenGL. This happened initially at the 1.1 update. After that, not only am I stuck on 1.0, but I can only use one mod, optifine. Before this, I had 5 mods installed and it ran fine. I don't even have OpenGL enabled, and this is especially problematic, since I am a mapper. I have windows xp sp2, 32-bit, 512 mb ram, and intel graphics card 650g or 610g. I can't remember.
 * The above unsigned report was unsigned and appears to be system related and not minecraft related. If this is your report please ask at the minecraftforum or the IRC channel for minecrafthelp - give complete computer details and full error logs please. "bad graphics card drivers" means the system's graphics card drivers are not correctly installed or configured or do not support OpenGL. -Aurelius 21:24, 22 May 2012 (UTC)

endless water
undefined When the multiplayer server i own (to connect i used direct connect) starts, i spawn in endless water. Is the problem the spawn point, or an actual error in the code?
 * The above unsigned report from Known bugs/Version 1.2.5 was incomplete. If this is your report please first ask at the minecraftforum or the IRC channel for minecrafthelp - giving complete details, such as server version, server properties, seed, and coordinates. Ensure both the server and client are 100% vanilla. Biome and Talk:Biome describe very large oceans are possible, and the suggestion is to try another seed. For what it is worth, I have a tested a few seeds with vanilla multiplayer minecraft and have never found "endless water" (I would be interested in seeds that give the claimed 25000 blocks wide ocean), but I have found a few cases with oceans of "only" 1000 blocks, but in each case above-sea terrain was found around 1000 blocks away. -Aurelius 21:46, 22 May 2012 (UTC)

Saved Game Missing! :(
I just experienced a blue screen error. After I rebooted my system, and restarted Minecraft 1.2.5 (vanilla), my current saved game was gone. Only my previous old saved games were shown. I was L21 and had HOURS and HOURS invested in this game. Does anyone know how to get the save game back? I don't even see a way to save a game with a different name to try to protect myself (I only see how to rename a save). Windows Vista Home Premium Minecraft 1.2.5 (vanilla) depressed 24.62.29.236 02:02, 28 May 2012 (UTC)

I'm sorry, but i can't help you. If you wanna get your items and world back, i hope you can work INVedit and remember your world seed. And if you get attached to a save, you should really back it up... It's just your average world corruption. If it's actually GONE, there's no way anyone can help... Use the run command or search bar and type in %appdata%, then navigate to the .minecraft folder, if you see the world, submit it to someone that fixes corrupt saves. --24.15.167.216 18:14, 4 June 2012 (UTC)

Villagers prefer dark over light?
Is it my imagination or are villagers preferring dark areas to lit areas while indoors (?during the daytime?)? Is this intended behavior in order to have villagers move as far away from the doors as possible while indoors inside naturally generated village houses? I thought the wiki stated that lit houses generate more villagers. I built a rather large City-house; it is a 4x4 chunk ring-shaped dwelling currently home to 400 villagers with the intention of being an iron golem farm, and I had encountered issues with nighttime lighting and dark corners. The entire compound was initially planned to be dark and spawnless, but it was flawed thinking in that mobs could not spawn in doors (they do). I noticed that in the darkest of ALL the corners in my City-house, the villagers seemed to be pressing the hardest to that spot to the point that there were piles of locked / collapsed villagers. I left that corner for last, and when I had completed the lighting project, the villagers had spread out as desired, throughout the entire compound as opposed to just the corner of 1 and 2 on the bottom floor.

There is still the issue of the villager AI attempting to cram 400 of themselves into a single arbitrary spot at night, but I don't think there is anything I can do for that.--PlNG 02:56, 1 June 2012 (UTC)

beige lines on maps
I am posting this here because I couldn't figure out all of the code to add it to the bug list.

When I reopen a map I have created in SMP, there are vertical beige lines (the same beige as the unexplored areas), at regular intervals across the map. Usually, they will clear as I re-explore the areas I've already mapped but as soon as I switch to another tool and then go back to the map, the lines are back. I think this started a couple of updates ago and maps made prior to that don't display the lines. This bug is easily reproducible as it happens with every new map. There are three other players in my family, all using different computers and we are all seeing this bug.

PS there is no category listed for bugs in maps or mapping.

Newly-Placed Pistons Receive Power From Two Blocks Up Even When There Is No Block In-Between Allowing The Piston To Be Powered
undefined Newly-placed Pistons will automatically extend if there is already an active power source, such as a Lever that has previously been switched on, TWO blocks ABOVE where the Piston gets placed even if there is NO block just ONE space directly above where the Piston was placed. If the power source is deactivated or removed, the Piston will remain extended unless there was a block directly one space above where the Piston was placed.

This problem does not exist if the previously-activated power source is two blocks away in other directions (to the sides, or from underneath) when there is one empty block space between the previously-activated power source and the newly-placed Piston. It only happens if the previously-activated power source is TWO block spaces ABOVE where the Piston is placed with the empty block space directly in-between.

TO REPRODUCE:

(1) Place a Lever on the side of a block three block spaces up so that there are NO blocks in either of the two spaces directly below the lever itself. (2) Switch the Lever ON so that it is an active power source. (3) Place a Piston two block spaces directly down from that previously-activated Lever (there should be one empty    block space directly between the Lever and the Piston). The Piston automatically extends even though it should not. (4) Switch the Lever OFF so that it is no longer an active power source. Or, just remove the lever. The Piston will stay extended.

EXAMPLE (SIDE VIEW):

--- --- |              |               | |               |               | |     Solid     |    Lever      |  (1) |              |               | |     Block     | (Switched ON) |  (2) |              |               | |               |               |  --- --- |               |               | |               |               | |    EMPTY      |    EMPTY      | |              |               | |    SPACE      |    SPACE      | |              |               | |               |               |  --- --- |               |               | |               |    Place      | |   EMPTY      |               |  (3) |              |    Piston     | |   SPACE      |               | |              |    Here       | |              |               |  --- ---

If the block space in-between the Lever and the Piston was not empty, the Piston would have retracted as normal in step four. Regardless, the Piston should NOT have automatically extended in the first place since there was just the one empty block space directly in-between the Piston and the Lever.

Some slight modifications need to be made to the steps above to compare the behavior when the active power source is two blocks to the side in any direction. Instead of using a lever in that situation, you can use previously-powered Redstone Wires instead. You will see that the Piston (again, TWO blocks away with an empty block space directly in-between) will NOT automatically extend when it is placed. However, if you have a solid block in-between (with no spaces), then it will still automatically extend as is normal.

The problem occurs when there is an EMPTY block space directly in-between the already-active power source and the newly-placed Piston when the already-active power source is TWO blocks ABOVE where the Piston gets placed. The Piston should NOT automatically extend unless there is a solid block between the Piston and the Lever.

IMAGES:

In the MCP code, the problem appears to be a check within the "isIndirectlyPowered" method of the "BlockPistonBase" class. It is doing an additional check for power two blocks above itself without checking to see if the space in-between is empty/null.

CODE:

if(par1World.isBlockIndirectlyProvidingPowerTo(par2, par3+2, par4, 1)) { 	return true; }

Sorry to break your good bug report, but this is a very well known bug, piston are powered by block diagonally superior or one block superior, but they do not realize it until they're updated, which occur when they're placed. 86.205.191.148 17:11, 30 July 2012 (UTC)

arrow/wall bug(?)
i shot at a wall in SSP (a log to be exact) with my bow, and when i tried to retrieve my arrow it was impossible and i just kept walking in (litteraly) the wall. i seemed to be only able to get a little bit into the wall but it was enough to damage me. i tested it afterwards but i got no such result again. has this happend to anybody else?

Fatal error occured (7)

Armor?
I cannot figure out which section is for reporting bugs in armor behavior.

Specifically, while armor is only supposed to take durability damage when it reduces damage, chicken eggs thrown at you will damage your armor even though (A) you take no damage, and (B) you are still knocked back.

So the armor has no effect but still gets damaged.

What is the proper section for reporting this? (Tested in multiplayer) Keybounce 17:18, 3 July 2012 (UTC)

Minecraft Server HTML Error
Okay so every time i try to login to a online server it tells my Failed To Login  and i have no idea what to do i have lookt trough 10 to 20 pages of answers to minecraft problems but i can figure out what to do. i know its a problem with me and not minecraft or the servers becouse i know my friend can join the servers no problem. i can join a hamachi server with no problem. i removed my firewall and it didt work. i have a legit premium acc if that should make a difference.

I think we can split the page
The fact that there are tons of annoyances make me think we should split this into two pages, annoywares and actualy bugs.

falling from a tall height then stuff being gone the next time u get there?
Ok so today i was playing my daily minecraft and a spider hit me pushed me of a ledge and i fall for a super tall height and lost 2 diamond sword pickaxe's and shovels, 35 diamonds, 30 iron ingots, 20 gold ingots, a whole dimond armour set. not only that but 3 stacks of coal, a honing bow, 60 arrows, and gold, and iron ores. And the next time i jumped down to small ledgess to get down the second time and the only thig that was there was 5 arrows and 2 iron ores and i searched in every little crease and cave system in the area, every ledge and cannot find any of my stuff!!!!!! any body else have this problem? not only have i spent time looking for it all to collect back again but all the time mining it all and now i prolley will have to spend days in a new mine trying to get more stuff!!!!!
 * It's a feature of Minecraft. If you unload a chunk (Not on SMP, read on for that) your items will instantly be gone. On SMP, due to how the server works, it takes 5 minutes or so for dropped items to despawn. However, if the chunk cache is unloaded, then it will act like SSP. (This usually only happens if players haven't been around the chunks for a long period of time.) Iyeru 15:12, 16 July 2012 (UTC)
 * I've had teh same problem on 1.2.5 in single player at least twice. Building a deep quarry then getting knocked into it.

 * I hate to admit it but even in the same quarry I can't get this to reproduce. I remember one of the times I died as I was shot off by a skeleton's arrow but even that is not causing the same bug to occur, the only difference at this point is the computer running minecraft so I'm baffled Huddersfudlien 17:16, 20 July 2012 (UTC)

insane glitch creatures
I'm putting the topic in discussion because it is very confusing. I was watching my sisters friends brother make a fail of a coaster when a white shape darted by. You may think it was a chicken but it was too fast and big and in the sky. I grabbed control of the mouse and looked up. There were giant floating white things in the sky. They would make shapes and dart away. One day a similar glitches happened to my friend while I was watching. The chickens texture was torn and blackened. They shot giant black squares with uniform holes in the surface. These events were quickly followed by Java e binary closing. --psycodragons

Wood Item Color wrong or just false Wiki?
According to the minecraftwiki.net recipe Wood Slabs and Stairs are supposed to have the same color as the wood they're made from, but they don't. My stairs should be dark, cause i made them from dark pine wood, but they always have the "vanilla-light-wood" color or "oak" i guess. Same for pine slabs... and jungle tree made stuff...

That's because that is for 1.3 not 1.2.5. - oplopy1234
