I was doing the “In Her Wake” quest and after a certain dialogue ended and went back to the normal screen i got stuck without being able to do anything
Can’t move , can’t open the menu , there isn’t even a ui on the screen
The only thing it shows is a icon of a eye above my character
And a few minutes later while i was writing this i got dc’d
Same here, I’m stuck in dialogue with the priest kneeling at the burning-stakes in the center of Margrave. I was talking to him about the quest he gives you. Now I can’t do anything, no UI, no buttons work… What do i do?
Edit; After 5-10 minutes i tabbed back to the game and clicked the mouse and I could advance the dialogue and end it, getting the quest. Phew!
Same issue for me currently. I gave it about 10-15 minutes and then had kill the game (and now have a 120min queue apparently 
)
