well, you could either look if its a kown bug, find the id for the item and add it to your invo, leave the quest, or stop and think what you may have got wrong or havent done.
I'm on Xbox so I can't change anything. As for doing anything wrong, I don't know what I could have possibly done. There were supposed to be two hags; one who I'd apparently proposed to, and her sister, who was supposed to attack me. The latter portion of the interaction occurred, the former did not.
If I can't find a solution to this... Fourth quest bug I've run across
1. My MQ is broken
2. Alteration Ritual Spell is broken
3. Helping out the female dark-elf mage at the college is broken
4. A Night to Remember is broken
This may well be the last straw. Bugs happen, it's understandable. But 4 different broken quests plus the screen freezing/crashing, the animation chopping up and going super slo-mo during certain battles, the disappearance of dozens of saves, and several other things have finally made me side with the people who said the game was released too early. I don't know what the technilogical limitations are, but if those are the reasons for all these problems then scale the thing back or spend a few more months getting it right. The game demands a lot of time as it is; at least have it work the way it's supposed to.
