A few days ago, the AI for the character who follows you to the Eldergleam did not activate: he neither approached you or followed you when you allowed him. And using any instance of moveto just made him walk back to the bench in the Temple in Whiterun. I had to use the console to complete this quest.

Now it's happening with the Greybeards; only the representive approaches you, the rest don't gather. So I can learn the word Ro, but not gain the knowledge from Einarth. And, unfortunately, it doesn't look like the console will be getting me out of this one. Manually applying a Dragon Soul to Ro does not move the story further. But if it happened to Einarth, it would likely happen to the rest anyways.

The only AI-related mods I have are the 4 Quest mods (No Mercy, etc) which shouldn't affect existing AI, and Live Another Life, which shouldn't touch anyone in Whiterun or the Greybeards with a DB background chosen. Is there a console command to force the Greybeards to initiate their 'giving' animation?

Bringing it back up for one last chance.
