I have been away from FO3 for awhile and just decided to play it again. However, when I change the style of hair in the character creator it doesn't appear ingame. How can I fix that? Thank you.

I have Anthony Ling's Coiffure installed. (It is the only cosmetic mod installed.)

Do you have a Merged or Bashed Patch applied? If so, you may need to remake it including Lings.
