Sometimes black textures, modded FO3 Goty

[Derpler]

Hi,

Sometimes when i'm playing some of my textures go black/missing.

So far i have had it happen when i'm using my pip-boy, loading a new area or using VATS.

On average it happens after 20-40 minuttes.

 

This is my first time installing more than 10 mods so it might be newbie mistake but so far i haven't been able to find a solution.

 

I have a pic of it here and my load order + installed mods in NMM: http://imgur.com/a/EiKE4

i also have Midhrastic ENB installed.
