I am unable to complete/ progress in a quest – Issue Fix
During some quests another quest activates which needs to be completed first in order to progress. Make sure that you don’t have another quest in your journal related to the quest that you have an issue with.
If you are unable to progress in the game, verify the integrity of the game cache and load a save file created before encountering the issue.
A variety of issues may be caused by corrupted game files, e.g. immortal enemies, crashes, glitched graphics or inability to launch the game. If you have encountered such an issue, please verify the integrity of game cache and load a game save file created before this issue occurred (if possible).
