Hi guys,
I'm just at the Molag Bal Quest in Cyrodiil and Melus Petilius lifts the Cursed Mace not who I beat him at the grave stone of his wife. The cause appears to be Morroblivion, is the problem known?

DAMolagBal cursed mace problem

Why do you think this has something to do with Morroblivion?
I have tested with this savegame. Is the Morrowind_ob.esm deactivated does the Quest normal and Melus Petilius lifts the cursed mace on. If the esm is activated, he only beats with his fists making the quest can not be completed successfully.
It would be nice what someone else is also testing whether the problem also occurs.

I can confirm that I have this exact same problem and it's also fixed by deactivating the Morrowind_ob.esm and it is ONLY fixed by doing that.
This happened to me as well, though I didn't know that it was morroblivion that was causing the problem. I ended up just completing the quest with console commands. It would be nice if someone with the knowhow could look into fixing the issue, I tried looking through the esm file and couldn't find anything myself.
