Sims can become trapped if you move objects or add walls, trees, etc. so that the Sim cannot escape.

Rarely, two objects next to each other will trap your Sim into place - a situation easily corrected if you move the offending objects out of the way.

Occasionally, a Sim will get out of a chair on a side that ends up blocking them in a small space. In order to leave the space, you will need to move the chair.
