Forum:Child Watery Death glitch... I need help on Sims 2

Er... I had trouble thinking of a name for thsi topic but anyway: On Sims 2, a child died of fatigue in a pool. Obviously a grave showed up and nothing happened for a few nights with the exception of my otehr sims mouring the grave. A few nights later, the water ghost turns up and creates puddles everywhere. Then, that random old woman from Strangetown (you know, the one with grey clothes and the graves in her backyard), randomly shows starts walking around my house. Eventually she says 'bye' and walks off. I decide to move the grave to another lot so the ghost leaves me alone. That night, a sim by the name of Witch Doctor walks around the front of the house. I can't talk to him or anything and won't leave, its been days now. He has a blue shirt, shorts and a white mask. There is nothing on this wiki about the Witch Doctor except a page about something from anotehr Sim game. So does anyoen know what do do with this mysterious Witch Doc?
