This is actually a pretty big issue, not just with myself, but with anyone attempting to finish this quest.
The Priestess of the Nothern ritual site is stuck kneeling and you can go no further in the quest. People are assuming everyone needs to leave the area, issue with that is, there may be someone AFK. If it all possible, it'd be nice to have her reset on her own but... Yeah, well, point is. It's impossible to get further.
This is on the North American servers. Aldmeri Dominion. Again, this isn't just me, anyone currently attempting the quest is just stuck... watching her kneeling, like some kind of sick horror movie right before she gets beheaded.
Er, well, you get the idea.
