Burnt sims after infant update

I had a similar issue last night. Working in a save of a large family with a butler, the butler appeared burnt. I thought he had been struck by lightning as it had been raining. I did not witness if this was the case or not. What I do know is that several days later the butler still had not showered, so for several sim days he appeared burnt. When my sim returned from doing a Home Decorator gig, the butler was cleaned up. I don't know if shutting the game down or going into another save, or taking a trip off lot will do the same things. I did not test further. I was just happy to see the butler cleaned.
