CC Skin tones glitched...

Hey,

I have over 100 GB of cc installed in my game, but recently one of them glitched and now all my sims have the same skin tone. Even when I change it/import a sim from the gallery/edit townies, they all have the same shade. I have NO CLUE how to fix this without dragging singular package files n restarting my sims every single time to see which file was the broken one...

Is there an easier way to do this? I've tried using the Sims 4 Tray Import to see if I could find the corrupted cc that way, but I've deleted all of the ones that were on the sims and it's still broken.... 

Any help would be very very appreciated.
