[ARCHIVED] [LS] Sim from Cupid's Corner Gallery won't change after CAS edit

This issue is happening to a sim placed into my world through a Cupid's Corner match from the gallery. I'm playing on a Mac. When I edited her in CAS, it appeared to save as normal, but all the changes reverted after returning to live mode. When I go back into CAS, the edited version appears again. In the relationship panel and in live mode, she appears as the unedited version. The edited version appears just fine in CAS, the map view, the main menu, and in manage households. I tested this both with and without mods, and the problem persisted, so I repaired my game and cleared my cache files, but her live mode appearance still does not match her CAS appearance. 

This issue appears to just affect her, as when I tried with my main household, her appearance saved and changed fine.
