Hmm, that's odd. You seem to have already completed all of the requirements, and most of the time, it works. You mentioned that you haven't met with the Night Witch in your current save. Try doing that, I think that's it.
Ok, that's that. It seems the game DID NOT COUNT visting nightwitch IF you disagreed to give her a favor which every sane person would do, who doesn't want to be in debt in some powerful creature. Hmmpf...
All I assumed that in previous playthroughts all you have to do is talk with "both" witches about mindcontrol NOT AGREE with both to their deals.
It's really not intuitive. I thought, "Oh, daywitch agreed to help me so I don't NEED the help of the 'other' one", well, apparently not...
Thanks. You helped me a great deal.
