I think my game fell prey to this, too. My Rock Star has had quite a bit of trauma in his life most recently, so if his emotions were imbalanced, I'm not surprised. I am surprised, however, how quickly he came down with an ailment. Yikes. His wife is newly pregnant with their sixth child. Trying to keep this hands-on father away from them, has been impossible, thus far. He allegedly got cured by a Naturopath, and his skin was clear for a few Sim hours, anyway. He went and held a concert in the evening and came back looking scarier than before he was cured! Not only that, but when I saved my game to shut down for that day, he had 2-days more of this ailment. The next day when I powered up again, it said he had 3-days. I do hope this doesn't spread to his entire family. If so, I'll just have to either stop playing this save altogether or disable this new EP (something I've never done before).
