Re: Sim appears frozen
@anneke33 Do you by any chance use the bb.moveobjects cheat when building? Because what you describe sounds like you have objects that were placed with that cheat enabled, such as clutter, which may then cause these routing/reset issues. Whenever a specific location repeatedly gets a sim (or sim pet) stuck like that, it usually indicates an object's blocking footprint. These footprints are invisible. You may also have too many objects on a surface without enough slots for them, or slots that are too small for the objects on them (yes, sometimes patches can change footprint sizes). Try moving around the objects in that room or on that table without that cheat enabled. You may even have to delete some of them, especially if they're from debug or have been changed in size with the bracket keys. This could solve your issue.
I hope this helped.
