This has happened twice already. My sim is a mermaid so I often see him wearing his swimwear around, but the other day I noticed every single one of his unique 12+ outfits were reset and all looked like one of his swimwear. I exited without saving and that seemed to fix it, but it's happened again just now, and I don't know how long his outfits been reset for so I can't pinpoint an activity that triggered it besides maybe swimming and transforming too many times. I really don't feel like exiting without saving cuz I know I just did some real tedious Finchwick Favours and I've been playing for almost 3 hours but I don't know what to do and fear I may have to bite the bullet and waste another entire play session.
UPDATE: Exiting to the map and re-entering the household seems to have fixed the issue. Still, got spooked real quick ^^'
