I use a personally modified version of ZaZ's drow race, other relevant mods are RaceMenu, XPMSE, Apachii Hair (for mod compatibility) and KS Hairdos. The thing is this: Having not touched Skyrim for a while and loading my old character, i decided to remake it. So i went into showracemenu to save the preset via RaceMenu. I then started a new game and loaded said preset with the same race and everything. But then i noticed that i couldn't change the hair at all. On the new character, it was the standart nord female hair from vanilla skyrim. On the old savegame it was the one from KS Hairdos that i used since i made the character. In both savegames the hair "slider" only shows random positive and negative values instead of the hairname/number, while not changing the hair, the haircolor value works fine though. I tried it with two other modded races, Ohmes Raht and some other that i forgot the name of. There the hairslider works fine, displaying the thousands of hairs without issue; same with the vanilla races. Now i'm not much of a modder, the most i did was replace textures or models and edit an entry here or there via tes5edit, i never liked using the CK and avoided it as i could. So far the only potentially useful information regarding a fix i found were aimed at people making their own custom race from scratch, using vanilla as base. But i need to know how to fix an already existing race mod that i'm not the author of.
