Hi, I keep getting a strange popup when playing. It doesn't happen right away or all the time but it does come up on a regular basis:

Confirmation of Changes
Cannot load matrial file dz\charaters\h
eadgear\data\militayberet.rvmat.

CONTINUE

I hit continue and it does so there is no issue there and I aviod militayberets. Is there anyway to fix this?
