After completing quest main objective to Defeat Baron Montclair (please find attached screenshot as proof), Revandis Ravenwatch just never appears, I completed this quest 3 times already, after restarting and reloading, because
I encounter same bug on 2 previous attempts, I REALLY DON'T WANT to do for the 4th time. You have you screenshots, I can provide you with my character name, PLEASE just progress me through this nightmare. I can't do it for the 4th time, because I know - It'll be bugged again. Thank You!
Opening support ticket as well, with reference to this post.
