All of vampire skin details (apart from glowing eyes and fangs) : vains, cracks, the ones on eyes, cheeks and mouth put on sims in the dark form in CAS disappear immediately after switching to regular form. 

I removed all the mods and custom content and the issue occurs regardless. Both forms are unlinked and I noticed this bug 2 days ago.
