This started happening in my game today. Both of my teens went to school in their PJs and came home still in their PJs.
Probably unrelated, but my dog has also picked up the photography skill since the most recent patch, per an in-game notification I received while playing last night. His skill improves the more photos my sims take of him. Lil pup's well on his way to becoming a master photographer now. Sure, he doesn't own a camera and doesn't have hands to operate one even if he did, but that doesn't seem to be stopping him!
If dogs can learn the photography skill now, I wonder what else they can do. Gardening? Handiness? Dishes?
Please let it be dishes...no, scratch that. Handiness. That way, the dog can fix the toilets when they break every day. Haha! 😉 😃
Back on topic, the whole going to school in PJs thing isn't game breaking by any means and I'll certainly take that over the kinds of issues we experienced post 11/10. It's workable, and I'll just have to remember to make them get dressed before they leave the house...but it would be very nice if that could be fixed at some point.
Adults are still getting dressed to go to work (at least so far) so it does seem to only be kids/teens and going to school that are affected.
