No Marcono, that's not right. From your screen shot it appears that you spawned like 1000 villagers in creative mode with only 2-3 houses and so they just have nowhere to go. The number of villagers should only be about half the number of doors. In other words, if you have 10 houses with 2 doors each, spawn 10, maybe 12 villagers, and see if 5 or 6 of them crowd into a single house with several of them being left empty.

Also when you break a block into a lava room, the lava flows out and kills you even though you can't see it, and when you drop a bucket of water, it pushes you away, but you can see no water.

More importantly, when you try to flip the switch it pops off instead of switching. This impacts all existing switches on half slabs.

This is not what this issue is about. The problem is that mobs cannot despawn
and therefore block the mobcap if your viewdistance on the server in multiplayer
or the renderdistance in singleplayer is below 9.

Wrong. If the map cap were hit, then you would have a normal spawn amount. Just because they are on the other side of a wall so you can't see them does not mean there is anything wrong with the spawn rate. The issue here is that the map cap is never reached because the mobs aren't spawning in the first place. Also mobs will despawn anywhere over 2 chunks away anyhow.

How can it be due to anything I have done, when I have done nothing? You assumed that I gave some sort of manual command to play this sound, when I did no such thing, and do not even know what command that would be. There was nothing else of interest in the logs besides the usual loading/saving, and errors about missing mob.witch.idle, which is reported already in another bug.

Whether or not you think it exists is irrelevant: minecraft thinks it should, and NOT due to anything I have done ( no commands, no mod packs, no nothing ).

Umm, no. I input no command of any kind whatsoever. I was just playing the game normally and got this error. I hadn't noticed it before so maybe they just added it in this last snapshot and forgot the sound file and to update the docs.

Please reopen this bug.

Apparently you are wrong, otherwise minecraft wouldn't be trying to play it and complaining that it can't.

That won't help if this bug isn't fixed by then, and it looks like it won't be.

That isn't valid villager housing Vit... you just have a bunch of villagers contained in a wall, with some random doors outside.

This bug has been fixed. A mod should update the status.

When shutting down 14w20b on Ubuntu, there are several hundred of these errors that fill the scroll back buffer, pushing off any previous messages:

[23:13:41 ERROR]: java.io.IOException: Stream closed

I don't know why boats cause such desync issues. I just pulled up to a weird house standing in the water on my boat, reached up and broke a block of the porch and the fence on top of that so I can place ladders to climb up. Each time I tried to place the ladder where the wood block had been, it changed back into a wood block. I finally got out of the boat and found I was several blocks away from the wood. The boat appears to drift off in one direction and when I swam over to it and tried to board, I could not. I quit and reloaded the game to find that the boat had in fact drifted off in the other direction.

This is NOT a duplicate of MC-2931.

So there may be a confluence of factors that result in low mob spawn rates. Initially I noticed that no mobs would ever spawn on the island I spawned on that is in the middle of an ocean. Even after spending several days leveling the island to be flat at sea level, and exploring and lighting some caves below, I never had a single mob spawn on the surface, and saw very few in the caves below. After finding this bug and doing further testing in creative mode, both on fast and slow machines, I can confirm that on the slower machines, there are fewer mob spawns, as indicated by the entity counter in the debug window. This persists even after flying very high to force underground mobs to despawn, and then dropping back down. In addition, even on the fast machine, a mob spawning on the surface of the island is very rare. A dup of this bug I found first thought that the spawns were inhibited by moonlight, so I tried building a roof of wood above the island in creative mode to see if that would make mobs spawn. Instead I got mobs spawning on the roof, rather than the island below. Based on this, it seems that besides the speed of the machine lowering spawns in general, they still have a heavy tendency to spawn in underground caves, and dislike spawning on uneven terrain.

The world seed I noticed this in where it can easily be reproduced in creative mode is -9084881734462559969, and this is all with 14w11b, My fast machine is a sandybridge ~3.2-4 GHz quad core with a radeon gpu, and the slow machine is a celeron with integrated intel graphics. The slow machine averages about 15 fps, and the fast machine averages about 35. The entity counts on the slow machine were typically in the ~30-45 range, peaking at about 75, and on the fast machine, they generally stuck to around 100.

Yep, creeper did it to me in survival mode in 14w11b with a standard size portal. For some reason it also causes a heart of damage when I return to the partial portal from the nether, and I can't relight the missing portal blocks.

So if they are spawning on normal difficulty, is that a bug?

Ahh, yes... I forgot it can be used as a dye.. I must have used it growing crops.

I edited the description to be more clear since I did actually use that word, but what I meant was the dark room you build to spawn mobs in a farm, not the thing you find in dungeons. I've always found that being too close ( say, standing in the middle of the room ) prevented mobs from spawning, and I've never seen them spawn on the surface that close either, but recently I have had a few spawn right in my face.

I'm talking about natural spawning mobs, not mob spawners.
