Hello here, i have a weird thing happening where some of my colonist have spontaneous hairstyle change and i don't know why or how.

So context first, i'm using a lot of gene/xenotype mod 'cause mods are cool and yours especially.
The issue happen when i added Big and small framework while i was already playing with Alpha Gene and only to my "Nereid xenotype" pawns (from alpha gene) although i didn't try every other xenotype.
Basically Nereid have a face cosmetic that make them systematically bald, but since i fear baldness myself i gave them hair using character editor, when i added Big and small all there hairstyle have changed to either bald or vanilla hairstyle and if i try to rechange hairstyle it randomly spontanneously change back to an other random vanilla hairstyle in the few seconds after.
It's not my pawn wanting to change hairstyle (ideology) it's just a random sudden change to vanilla hair. So not gamebreaking but annoying.

I haven't make deep test to see exactly if it happen with all head cosmetic but it also affect my custom "oni" xenotype i made with big and small xenotype but only if i give them the cosmetic horn head, weirdly enough if i give them a hair gene like "short hair" or "long hair" it always pick a hair style matching that gene but a random one that i can't apply myself and even if i use the styling station it just switch to a random other after a few seconds and i can't give them any hairstyle from mods eitheir they change too. Once the new hairstyle is randomly applyed it doesn't change anymore even if i restart the game.

If i remove big and small it doesn't happen anymore so i guess there's something going on here between big & small and Alpha gene, maybe ?
I didn't tested removing alpha gene since it delete all my alpha gene related pawns if i do...
If anyone have an idea on how to fix it i would greatly appreciate it.
