One of my Sims has seemed to have developed a chill from swimming, even when he hasn't been swimming. Both of my Sims were in the house, the thermostat was on warmer as it was cooler and my Sim turned blue. His wife was fine, even though she'd been swimming. He however had a chill from swimming, even though he hadn't been.
I've noticed a few other people have been getting this. It doesn't seem to bother him that much though, and tends to get overridden if he's happier about lots of other things. Just weird to see him going blue off and on quite randomly.
