So I keep having this problem where my first person textures are breaking. The textures are just flat and highly dependant on the surrounding area for what colour, sometimes they even disappear. I can't explain it much more than that except that it only fixes when I re-install the whole thing. Anyone else have this bug or know a better solution than waiting an hour every time it breaks for the whole thing to reinstall?

It also removes spell textures and fires along with a few other things.
