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

I edited an existing sims, don't know what pack he's from or if he was a randomized sim, changed his outfit, hair, face, pretty much everything, and he looks like the old version in live mode but the new version in CAS. I restarted my game and repaired files and everything, but he still looks the same in live mode. I'm honestly so tired of these huge bugs making the game nearly unplayable.
