FaceGen error on the CreationKit

[Adesa]

Greetings

 

I'm pretty new in messing with the creationkit, so I'm sorry if this is a basic question, but I searched and still can't find the answer.

 

Whenever I open the skyrim.esm, there's always that error about spaces, but form I read you can just ignored that one.

The problem lies whenever I want to edit or add new NPCs, even from an already working mod or even vanilla NPCs. The error occurs when I want to preview their models. Face and full body alike.

 

It give me an error about FaceGen, something about the forehead tint mask not being the correct 256x256.

But i tried opening the file and it's still 256x256. So I'm not sure on how to fix this

Is this because of face mods? But I don't encounter errors during the game.

 

Because of this error, I can't edit or add NPCs without getting CTDs when i got to the same cells on them.

I even tried opening an existing NPC mod, not editing anything and saved. That gives me CTD as well.

 

Any help on this will be appreciated.

Thanks!
