I'm having a REALLY weird glitch on the Blood Curse quest; at the point where I'm supposed to cross the fog and travel to Vergen. When I enter the fog, I remain in the alternate reality spectre battle for a few seconds, and then instantly load back into the area outside Henselts camp. at this point I can run through the area covered by fog, but the spectre battle won't load up again, all the area is unloaded and missing all the clutter/details items like trees, rocks, ruins etc. I can even run to where Vergen is on the map but it's a ghost town, missing all npcs. No cutsecenes trigger either so I can't progress at all. Halp?
