Try a more recent seed and try to find sheep groups that are near each other (ie generate at the same time). I'd try the seed and coordinates by Vitold but I'm curently away from home so I can't try reproducing this.

@Deano: This bug is bad, but it's not awful and it doesn't plague us for 4 years or something like that. There is a very simple workaround: Just don't reuse world names, if you create a new world, use a name you didn't used before (append a digit or whatever). Then you should be fine.

Both, probably. But the main issue is that they don't spawn naturally in the jungle on peaceful difficulty. Which makes cats completely unavailable when playing on peaceful without cheats.

It's difficult to find good seeds to reproduce this, bit it seems to be still present in 1.8.1-pre3. Seed 8807133522892241494 at X=75, Z=320 seems to spawn purely white sheeps for example now.

Something like this happens if you erase the chunks on the right side (with Mcedit for example). The game regenerates trees and grass and so on starting from the middle of the new chunk, but things near the edge will be missing.

Confirmed with placing a ladder on spruce wood or planks. Other wood types seem to be affected, too, but I didn't test them all.

An easy way to reproduce this is to build tiny pyramids out of stair blocks and then surround them by solid blocks like in the screenshots I posted here.

Also, I noticed it's direction dependent. Make sure the hole is facing west or north, or it will work fine.

screenshots of simplified version

I can reproduce it.

Gary, that's possible, but I'm pretty sure there is no real need or reason to display the hitbox of an otherwise invisible technical box to the player. The engine is certainly capable of removing or changing the hitbox for certain blocks. So I still think this is b bug and should be fixed.

This has to be expected, as the water in the rivers is placed at sea level. What's your proposed solution? Lower the terrain around rivers? Might look stupid...

I can confirm it's fixes in 14w08a

I can still reproduce this in 14w08a

Still reproducible in 14w08a using the seed Tails posted above.

Yes, still in 14w08a.

I'm using
java version "1.7.0_25"
OpenJDK Runtime Environment (IcedTea 2.3.10) (7u25-2.3.10-1ubuntu0.12.04.2)
OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode)

Still in 1.7.4. Will test snapshot when I have time to update.

Note that this bug only occurs when you exit a server you just created/started a few seconds ago with a fresh world. As I said, it's probably happening because the initial chunk generation is still happening while the server is already exiting.

David, the minecraft wiki is not an official mojang site and is edited by random people. Dinnerbone personally said it will be fixed in 1.7.3. Who do you trust more?

They will fix it for the next version, be it 1.7.3 or 1.8. Just be patient, they will probably upload it once they're back from Minecon.
