When I talk to yuri the progress does not move
So I was doing the campaign with a friend and around the time you first meet liath, I took a quick break and skipped to lagoon.
I got to the end of chapter ten and then I went back and walked to do chapter 9 and 10 over to see if that would trigger it, it did not.
then I went back and rekilled liath. Did not move the progress
I am thinking I need to redo the step right before I get to the portal and the tower with liath so she opens the way again but i am not sure how since my quest marker is not pointing to anything I can do
