I need an exorcism performed on my game I guess. I have seen several family members, from different generations, heads spin completely around on their shoulders. Most the time it's the children when they're sitting in their room playing with their toys, but I've also had it happen with my adult males when they are in the bedroom trying to make a baby. As long as they don't start throwing up pea soup, I'll deal with it.

All the homes in VF are possessed...
Just kidding.... It's not a bug, the same is happening in my game.

It is happening in mine too.
I try to ignore it.

lol! Yea, it happens in my game too and the first time I saw it was with a kid playing with the toys. Sort of creeps me out too, so I just try to ignore as well. These little peeps seem VERY flexible, lol!
