My vault keeps freezing when I try to bring up the dwellers that are outside the vault since the update. I have two people waiting to be dwellers but I am at maximum capacity. They have been there since before the update and they did not cause any issues. After the update I have had some dwellers return from exploring. I cannot bring the explorers back into the vault add the game freezes. I tried going into the menu and touching them directly. Both ways cause the game to freeze. Restarting after force stopping the app restores the game but as soon as I try to collect the explorer it freezes.
