I just experienced this problem while attempting to move out my legacy family. After several freezes, I finally hand placed the majority of their belongings into the family inventory, and was able to move them into their new home in a matter of seconds. The only problem is that the family inventory is apparently borked now. I can't place the teleporters, and I keep getting the "grab" hand instead of the arrow, so I have to keep restarting the game to get rid of the damn hand.
