Graphics problem with Super Mutant Redux

[SteelPhoenix78]

I've been using SMR for a while now, and I've really enjoyed it, but I've run into a problem where Super Mutants are spawning with their face textures completely missing (as in this screenshot; you'll also notice that although the mutant is tagged as a Nightkin, the skin isn't the right color https://drive.google.com/file/d/1AxOKrEk00AH3MqWja9yFSL4g2rUReJZr/view?usp=sharing). I'm currently back to using SMR version 1.4 because I'm not partial to the changes made to Behemoths in the most recent version (they default as friendly to the player to offset how much tougher they are, & won't aggro unless you attack them), or to Suiciders (they don't fully blow apart, which doesn't feel believable to me). I have started from fresh game saves, as well as a total reinstall of the game and all other mods (my full mod list is here - https://docs.google.com/document/d/1gvTKxt4FinvPG_YIi1WfcH0CFrGx59BvAByGDVYP7GY/edit?usp=sharing). Any ideas on what, if anything, I can do to fix this? Thanks!
