the face a differetn colour from the body issue is due to a texture path error, from what ive seen i dont think many of the mods made to make npcs look less ugly usually changes textures, just head meshes (except for the body replacers, those do replace textures) but either way to fix that your going to need to find a texture of that race, find out the path the current texture is using and rename the new texture so that its the same as the miscoloured one then simply replace i had this same problem with my dark elfs for awhile, it made me sad
