Face Texture Error

[Deleted1217574User]

I'm running Skyrim on Ultra-High graphics settings, with Xenius' Face Mod (I forget the name) as well as FXAA and a couple other graphics enhancing mods. However, in some lighting, I have this problem, where a character's face looks to be detachable, like a giant puzzle piece. To my knowledge, this affects only my player-character, and not any others, though that may be only a matter of context. Additionally, I have this error on multiple characters, including a Breton, Imperial, and Nord (all female; no issues with male characters yet). If anyone knows of a way to fix this, I'd be much obliged. Cheers!
