I am just posting this for reference, may other people stumble upon the same issue. Ok so it didnt work at first, viewing the values of the morph line i sensed something wrong, the new ones were shorter. So i tried with another character, and the face wouldnt chage either, then I realized that was because i had previously overrided it with a *.mor character so i just got rid of that value and it worked. (Which makes all the sense in the world) Also I noticed that you cannot change anything of the pre-made characters when starting a new game, but if yo go back to the character creation .exe you cam personalize there. Now another question arises. Why would the hairstyle from More_Hairstyles_0_51-392 work, because i got mitten hair, but cannot select them on the creation ? cheers!
