Hi
I'm doing the Hermaeus Mora quest, in which you should kill one from every race and the souls are supposed to be trapped. I successfully trapped 6 souls, but after that it just doesn't work. I cast the spell Hermaeus Mora gave me on them and then I kill them with Duskfang/Dawnfang. the souls are not trapped. Have any one already dealt with such problem?
I have all official updates and patches and a few unofficial patches installed.

UPDATE: it solved the problem:

Problem solved, but we will still move this to the CH&S forum.
