Did you save WITH your modded armor equipped and you are loading that save to test changes? If so, reload to an older save before you "found" the armor in game.
Save games can still hold texture data so that is why you are supposed to test mods fresh with a save that has never seen said mod.
So I saw this suggestion and uninstalled the mod, then loaded the game, did a clean save, reinstalled, made my edits again, started the game and again, my changes were not there. How exactly can I get my save game to stop loading what is essentially a cached version of the mod?
Another alternative would be to name the nif file something new and then in CK edit the object to use the new nif file, but every time I try that CK crashes.
