I've started playing the new Tiny Death Star game lately, and there are special charecters that come every now and then (Princess Leia, Han Solo, Boba Fett, etc). I was wondering, Is it possible for them to move in on a residential level? Whenever they're on the elevator, they have a '?' above their head. Sometimes, they chose to go to residential levels, but they're either full, or not finished building. Is there any chance that one would move in, or is it impossible?
