Losing my mind with a sound

That might have been the ghost hunting music. I used to hear it at random times in my sims' houses, and sometimes it would follow them when they went elsewhere. I finally realized it was the music for when the ghost hunter is working. So I started checking around the neighborhood whenever the music started, and sure enough, there was a ghost hunter working at one of the neighbors' houses every time. So I now have the ghost hunting career disable from my games with NRaas' Story Progression.
