I started the "Blindsighted" quest and I won't spoil anything but I reached a certain area in the location I was supposed to go and I suddenly started experiencing lag, unplayable lag. Anyway I reloaded a save where I was out of the area and no lag at all it just that one area. So I'm just wondering if anyone who's done or attempted this quest encountered any problems.

Is that one of the larger areas of the dungeon? If so, I have the same thing there. Turning the xbox off then back no usually fixes it. For some reason just reloading the save does nothing.

I did the quest twice with two different characters and had the same lag at the same spot, and both times restarting the xbox fixed it

Ah, that seems to have worked. Thanks.
