[ARCHIVED] Sim Gets Fear of the Dark After Being Cured (Patch 1.97.42)

One of my sims has the trait "fear of the dark". She developed this when she was a child. I have tried everything. Conquering it, physically removing the trait with cheats, and asking the parents for comfort and advice. Nothing works. She even gets scared during the day, which doesn't make sense. I don't know what to do. But it is really annoying how often it happens. I was wondering if anyone else is experiencing this or if it is a bug itself.
