Outfits bug out in every way possible

Since the latest update, the outfits bug out all the time in every possible way:

• Sim portraits show the wrong outfit, not what they are actually wearing. E.g. My sim is wearing everyday outfit, portrait shows sleepwear, and so on. I have seen this one reported before.
• My sims autonomously change their outfit to the one that their portrait shows. E.g. My sim autonomously changed back into sleepwear while in the onsen bathhouse.
• When the above happens, I can't make them change back into their current outfit because the outfit chooser says "This is your current outfit.". E.g. Sim autonomously changes back into sleepwear, I click on Change outfit and try to select everyday wear but it's greyed out saying "This is your current outfit".
• Sims bathe and shower in their clothes. Toddlers being bathed are also wearing clothes. I have seen a YouTuber having the same issue.
• Sims going out into the cold/hot weather don't autonomously change into their cold wear/hot weather wear.

To sum up, sim portrait shows wrong outfit, sims don't change when they should (e.g. showering, weather appropriate, etc.), but they change autonomously when they shouldn't, and the game doesn't recognize it and thinks they're wearing the same as before, not letting you pick it.
