Bonnie leaves a lot faster on higher nights than you think.
Foxy should be watched, for 6 seconds then go back in for 3. 4am is when you leave your cams on 6 to stop freddy. Use your ears for the rest.
Btw check chicas light first then bonnie cause no matter the night, shes not all aggressive. When Foxy too far out, focus on bonnies door and really listen (do not check cams).
