After a month (I'm new and still a little underpowered) I found someone running the mission. We ran it and killed Kela De Thaym, but the door never opened, and it eventually timed out and I didn't get credit for the mission of course. Please fix this issue, as I really don't want to have to keep spending time successfully "completing" the mission and not getting credit for it.
Not sure if it has anything to do with it but during the fight she did get stuck behind the exit door but we could still do damage to her. Then she respawned behind the glass, and the fight continued as normal.
