I also noticed this was becoming a problem when they introduced the multitude of skin tones and color, but the mod still worked on aliens here & there. But still works for my normal Sims in CAS. The skins are now the basic six colors that EA has for aliens. Since that update this mod no longer works for my alien sims. Purple vampires, yellow aliens, grey normal sims etc. So before the ominous mid- july update, I had the 99+ colorful skins mod on and it worked for all sims, no matter the genetic makeup.
