Cribs are disappearing as I try to place them.

I ended up doing a Repair on the game - I've been playing since the beginning (TS1) and repair was never available so I still don't think of this option - and it seemed to fix it on a couple of houses I tried. But the main one I play just wouldn't work. I ended up bulldozing that house and am starting over. Made me sad and a little sick to do so, esp since I'm running back and forth to the hospital and was just looking for some "light" play, but ya gotta do what ya gotta do.
