I got my Vault to 73 dwellers and was loving this game. I got on today and one of my rooms says there is an infestation but nothing is there! All my people are running around and my vault isn't producing and the whole thing is completely useless now. Nothing I have tried works, it just always stuck in this state now.
How do you fix this? This is really dumb and i'm starting to think I just wasted days on a game.
