Lethal Heat Moodlet Problem

I have yet to see this in my game. But, my Global Superstar finally held his first concert in a ginormous venue I forgot I downloaded from the Gallery, and the poor guy shivered like I've never seen a Sim do in between songs! Happily, he was wearing a thick winter sweater, gloves and a hat, so I never got a notice of impending doom, else I would have cried. (I had to roll back two game saves, recently, to get him back to where he was prior to my very first emotional deaths in my game, just to set things right again.) Oi!
