Re: [ARCHVIED] [S] NPC Sims wear random cold/hot weather outfits not assigned
@Pocketfloof123 Usually if the outfit isn't on the Sims when you switch back to them, it's the Sims not switching back as described in this thread: https://answers.ea.com/t5/Bug-Reports/OPEN-Sims-don-t-change-out-of-situational-outfit/m-p/8068958#M99865.
Situational outfits do apply to all Sims you don't play at a time so it can happen to your rotational played Sims outfits.
So while the other I linked is more about situational outfits being extra weird with clothing, that one is about Sims not changing back. From what you're describing, you're seeing the outfits being extra weird.
This thread here is probably a mixture of things but from what you're saying, your post is fine here if it's specifically about cold/weather outfits.
As said, there's so many outfit issues, some older, some newer, some probably the same root cause - the situational outfits which just not work well as well as random accessoir being added to them.
I don't think we need another thread at this point but if they ever take a shot at fixing them, all threads on outfits will probably need to be revisited/closed and new ones created
