Playing game at work during lunch rushing to build some caps up. I have an incident accur as I was returning to work and locking my phones screen. The incident was a fire, much like the invincible roaches and rats... My three dwellers are attempting to put out fire to no prevail. They are not loosing health, the fire is not spreading, the game is just locked up not being able to build or rush any other rooms. Please help this is a pretty big annoyance.
