I'm playing on a 360, cruising through the Undead Legion quest chain. However, when I enter the sealed vault in the "Battle Below ground" quest, the screen goes completely black and I can't move or do anything. I can still see the quest markers on the mini-map, but they are just glowing circles against a black background.
Has anyone else experienced this? I teleported out, saved, and reloaded, but the same thing happened. Any known causes or ways to fix it? I'm bummed I can't get a Boneslicer.
