After defeating Salokhnir in the 'A Blade in the Dark' quest, I can't absorb his soul. Anyone else had this problem? Is there a fix?

Did you try reloading saves and deactivating mods that may conflict?

I have this issue on the PC version as well. I deactivated all mods, and went back to several different save files and the problem is still there. This is very annoying as you cannot advance the quest any further with this problem.
