Hello, I have quests wherein I was inside a dungeon (teleported by an NPC) then game crashed, logged back in and cannot teleport back via the NPC. The quest cannot be dropped so I cannot re-do it. Now I'm stuck. It's a main quest so I think it;s kind of important. What do I do to fix this? Quest is called Truth and Illusion IV. Regards, Edit: A guildie helped me out. It's okay now.
