Now I am worried for all the families that I haven't fixed their outfits yet. I hope they don't die. So far, no one has turned blue or died (as far as I know).. Maybe a solution could be instead of having hot weather and cold weather outfits be separate categories, they can be subcategories within each category. That way your nonactive and active sims can dress up for the weather autonomously regardless of what category.
For example
Everyday
- Hot Weather
- Cold Weather
Athletic
- Hot Weather
- Cold Weather
