Entities get pushed into and through walls when relogging

Rabbits (and presumably other entities, but most likely rabbits because they are very small) get pushed into walls and through doors when you exit and re-enter a world.

Steps to Reproduce

1. Make or go inside a house with a door.

2. Fill the house with rabbits until you can't (or barely can) see the floor.

3. Exit and re-enter your world. A handful of rabbits should have escaped out the door, and some may have gotten pushed into the walls and died.
