[LS] Cupid Corner Sim reverts to old appearance/outfit on travelling

I had a randomly generated non-playable character join my household and I changed her hair, but when she showers/bathes, wears a wedding dress, or wears the postpartum dress her hair reverts back to before she was in my household. Her hair remains how I changed it in CAS. I don’t have any mods or CC, both hairstyles used are from the game.
