I was having a two different face bug problems that needed different solutions: The first was with a follower mod that the orc followers' head was brown. Using the CK face gen export command (Ctrl-F4) corrected that problem. The second was more difficult to solve it was the vampire face bug affecting the female lumberjack at the Half-Moon Mill named Hert. I had tried using the CK, Skyrim NPC Editor, certain bug-fix mods, console commands mentioned in the Skyrim NPC Editor readme file and none of them solved the problem. While reading again The Unofficial Elder Scrolls Page list of console commands a line in the notes for the setnpcweight caught my attention "Saving and re-loading a game after it's been used on an NPC may result in neck seams, as NPC head meshes are pre-modeled and not procedurally generated to the new weight value". An idea formed from (head meshes, pre-modeled and not procedurally generated new) and a post I had read sometime ago (that the game can forget part of the data on the NPC's appearance) and the order the games gets data (In Game --> Save Game --> Mod Files --> Skyrim Data). So I just tried the setnpcweight command and see what happens. I had used the Skyrim NPC Editor to find her weight which is 10 and then used the targeted console command SETNPCWEIGHT 10 and the face bug had disappeared. Her head is back to normal with her facial scar and the vampire eyes. Saving the game made the fix permanent even when I loaded from a much earlier save than the one I used to fix the error.
