In response to post #10553560. #10560317 is also a reply to the same post.
I've opened the esm file, opened the Brisa file that exists under the female section of her custom race, changed the race and verified that the changes were present by viewing the preview in the face tab, saved the changes as an esp file and loaded the esp at the end of my load order. When I load my current save, she is exactly the same as before. I am new to Geck and any direction you might provide would be greatly appreciated.
