When BB gets into the office (yes i know you're not supposed to let him), he won't go away. I know he's not supposed to but it gets kinda annoying because he doesn't have much effect on the map. I know when Foxy is added, he will make more sense but for now maybe you can make him go away when you get killed by anyone? (Also there's a glitch where BB can be in the office and in the vent at the same time. If you watch LordMinion777 he finds this while he's playing the map.)
