That must be some kind of AI conflict. Since they changed some AI data.

Well, yep! Should be ... Ticking entity ... Well, I hope it gets fixed, because that minigame is going to be evil.

I was breeding a few animals

It seems this happens spontaneously too.

My server crashes a lot. I've submitted the issue myself. This is a real game braking bug. Bugs that cause the game to crash. This bug should have a high priority.

I had this crashing problem too, and I also suspected it had something to do with the AI. However, in 14w32b, I spawned a RIDICULOUS amount of animals, (mostly rabbits, since they caused my crashes earlier) and I didn't get a crash. The framerate plummeted, but theoretically, the point is to slow down the game instead of kill the game.

Anyone else with odd mob crashes in 14w32b?

No more new tickets of this kind since some snapshots, assuming fixed.
