Today in Skyrim

Hi readers here's what I did today in Skyrim. I started by getting out of Cracked Tusk Keep and then I decided to go to Forelhost to defeat Rahgot and get the mask. I started that quest which you do when you go in there and I kind of got lost in the Stronghold but then I managed to get to the Crypt. Then I discovered this bug. At the Draugr Deathlord room in the crypt, that Deathlord kept respawning! Anyone know a fix?
