Leave the dungeon completely then reenter and see if that fixes it, sometimes a rezone will fix little glitches. I myself have never encountered this problem so it might be a rare occurance.
rly kind of you to take time to help but no way im running the entire dungeon again on the off chance the bug will not happen again,maybe i ask for my money back and a bonus for wasting 2 hours of my life.
Oblivion had many bugs but i used hacks to make it playable but this.......well ppl saying its game of the year and scoreing 5/5 on amazon..makes me wonder
