I've never experienced that bug, but I did witness pretty disturbing things happening in my game. Once the babysitter I had hired, a pretty normal looking old guy, proceeded to take off his clothes and go play with the children naked. Or, more accurately, stand naked in front of them while they were addressing him from the floor they were kneeling on (probably doing their homework or something similar). I like dark humor so I couldn't stop laughing but I still dismissed the weirdo. Never happened with any other nanny.
