So I'm in The Snitch. Midway through one of my part members goes AFK with no notification. Obviously, the entire group is unable to progress on the quest because we can't assemble near whatsisface, the Halfling. We've already spent 40 minutes on the quest and now I have to wait for a half hour for this guy to DC.

What's the correction action to take? Is there a report for something like this? This guy has wasted a lot of our time and ruined an otherwise good quest run.
