[S] Sims wearing cold weather outfit every time game loads

When I load my game, my sims are always wearing their winter clothing inside. Instead of wearing their PJs or their everyday clothes like I left them when I closed the game. This happens during the winter despite the heat being on and fires lit. 

This doesn't happen in the other seasons. Nor do sims default to their hot weather clothing in the summer. 

It'd also be nice while addressing this bug if sims would change out of their winter clothing and back into what they were last wearing when they come back inside. 

I'm on a PC. No mods or CC.
