Help! cannot summon Dremora Lord

[Pixelator]

I completed the mission (to get the sigil stone) and then tried to summon the dremora lord after and it didnt work. i dont know if i looted it but it is still at the roof at the college and i cant interact with it. not even attack it. Although i can see it its as if the dremora is not there.(I can post a screenshot but i dont know how)


I fully complete the animation and i hear the sound but its not there. I dont think i have a save even if i revert back ill lose lots of gameplay.fix plz?

The Dremora may not leave after having given you the Sigil at the last summoning. He will instead stand there in a state where he cannot be damaged nor interacted with. If you have finished the quest, however, this will not impact the ability to summon Dremora Lords or use the other Master spells. This is a known bug.

any way i can be able to use the spell then?

To me it makes no difference, i tend to use duel cast dremora's anyway, as i see no point to a permanent one.
