I have a sim stuck on my lot and I can't get rid of him!
My sims invited a few of their friends round and by the end of the evening everyone went home but one sim, he stayed at the bottom of the staircase in their front garden. He's been waving around and fussing like there's something in the way but I can't figure out what. None of my sims can interact with him, so to them it's like he's not there. I've tried deleting the staircase, lowering the terrain so that you can see his feet clearly but he still can't move! He's not dying of hunger, he's getting tired, hungry, smelly and very miserable.
Does anyone have any idea how I can help him out?
