her name is Maddy and she blocks the door or the camera, the only way to get her out of there is to wait or distract her using the microwave in one of the cams where cleaning bot roams. Dont use it too often as it can break after a couple of uses.
Dw, I know how to deal with her, I was just sharing a weird thing that happened once on a later night.
it really isnt that weird but maybe when you use the microwave alot she starts appearing? i dont know its just a theory
