Forum:Clement Riffin "haunting" other houses?

I loaded Appaloosa Plains with the intent of clearing out the old Sims to make new ones. Then I come across a Riffin household, and it's not the one with Calvin and his siblings, either. It only has Clement Riffin in it. Isn't he supposed to be dead? Yeah, he is. So when I tried to evict him, the game told me that there is a tragedy there and that I have to wait until it passes:



It wasn't going anywhere anytime soon, so I decided to go into the household and let it happen so I could go back.

Imaging my surprise when it showed that he wasn't even there at all!



And when I exited it, he moved to ANOTHER house and it did the same thing! Is this supposed to happen?! Can I even get him back to where he was supposed to be?
