Any idea what mod is doing this?

And how to fix it? I must have done something that royally beeped my game so I thought I'd try a new fresh save. Tav in CC does it on body types 1, 2 and 3. #4 doesn't have the "mud", just the weird bony legs and arm.

When I did manage to load my old save, this was happening to Tav too. When I went to fix it, my save bricked completely and I couldn't unbrick it. So whatever the problem is, it must be related to this mod.

And I have nearly 300 mods that all worked fine til yesterday. I think there might have been a script update that caused the problem, but I'm not sure.
