Hi there. For some reason, a lot of NPCs are missing half of the lower part of their faces. Instead, it's just a black area. Sometimes facial hair will cover the black area, too.

For some reason I can't post a screenshot, so here's the chopped up link:

Is there an easy way to fix this?

I'm sure I left out some important info, so just let me know if you need any more.

try disabled all mods.

It's the same without any mods enabled. The first time I had the problem was with a fresh install.
