So I just finished NWN2 and Mask of the betrayer. I go to load up Storm of Zehir for the first time and from the moment I start the campaign, theres a very weird graphical bug thats keeping me from seeing most of the textures. It happens on the boat as well as on land later on.. I've turned off all the graphic options and it doesnt seem to make a difference. As far as I know, my game is fully patched. What's wrong with my game??
