I tried to edit the appearance.2da file to include mods I use and I noticed a bug. On one of the very last rows 691 for "Unique_Kaah" on the attribute row "skin" instead of the usual 4 times: "****" (which I guess is just a placeholder for 0?), it only has 3x : "***" which prevents saving the appearance.2da file and making any manual changes unless it is changed back from "***" to "****". I used 2DAEditor. I know almost nothing when it comes to modding so maybe I am being stupid here.
