What if there was a chance for, during the night, some npcs attempt a break in?
It's like in the movie. They break in and try to steal things. The animatronics will probably ignore them for the sake of it being like a task, but YOU have to stop them or you wont get paid. There is a way to implement agony into this, but I'm too stupid to think of it.
Idk if this is planned, but no one has suggested it yet.
