Elder sims just walk around naked?

My sims occasionaly get hit with the no-clothes-after-shower-bug. No one seems to care and I think, it´s hilarious. Some sims seem to be affected more often than others, and I had one female sim in particular, who got it a lot after she turned elder. I just assumed, she was getting a bit loopy with old age. :D
If it bothers me for some reason, I just let them change into an outfit.
I only ever see it in my active family, though.

(Can´t see anything, but i put it in a spoiler, just in case.)
