I realized by the time I had a level 42 character that I had not done the level 12 Banished Cells quest, so I thought I'd try it alone. I made it through to the last boss, killed him, got the achievement, and oops...I had one more keeper to rescue. I went to rescue the last keeper, and then find out there's more to the quest...killing the boss I already killed. Now the quest is stuck, with a directive to kill the daedra surrounding the binding stone, but I already killed them...now it appears I cannot finish the Banished Cells without abandoning and restarting the quest. Is anyone else having trouble finishing this quest?
