Minecart and mob teleportation.

When a minecart with a mob standing in is destroyed, the mob will teleport to a different location. Sometimes they reappear, others they dont.

Effects relocating villagers etc

Will also teleport through walls. This is problematic as where I keep my villagers is a 2 by 2 hole. Usually i would destroy the minecart they came in and all was fine but now they will go somewhere different.
