Strange Zombie behaviour

[confuser]

Since the 1.6.4 update, Zombies act strangely even with the latest 1.8 snapshot.

They look at players but don't attack. When they try to move, they are very jumpy and end up just spinning around.

This occurs with and without setting the standard goals and without.

I have seen this as well. I was using version 1.6 before the update, now with the 1.8-snapshot, it is completely broken for the zombies. I haven't tried other entities, but I, too, have tried setting standard goals as well as my own goals

Same problems here. They are just fixated on their spawn point. No amount of desires or anything seem to get them to stop staring at the spawn point. I'm testing other entities now, but its also being buggy.
