So I have a bunch of default replacement skins for my supernatural creatures, and I decided that I wanted to change the eyes on the skins. I followed a tutorial here, and all the skins of the creatures changed eyes, except the alien and zombie. I thought maybe it was the replacement packages I was using, so I download two different ones and replaced those textures. The eyes still didn't change. The skins are fine and change perfectly, but the eyes refuse to...does anyone know what is going on here? Thanks for any help in advance.

All EPs except OFB and Pets
All SPs except Celebration
I used Pooklet's Supernatural Compulsion replacements first, then Rensim's Freshie Aqua and Navetsea's F-INevolution4 zombie.
