In the group dungeon in Deshaan. The quest in there is bugged.
None of the taskmasters appeared and leaving and reentering the dungeon is not fixing it. This renders the quest impossible to complete and the dungeon being left black as a constant reminder that there's something in the game I haven't done. I'm going to try abandoning the quest and restarting it, but this is a serious problem, you guys need to fix this.

I'm on the european megaserver and I'm Ebonheart Pact.

EDIT: I abandoned the quest only to find out the guy wasn't there to give me the quest back.
I had to leave my group before the guy would appear again.

I also found out why I didn't complete the objectives the first time I went round with my group. MY FRIENDS KILLED THE TASKMASTERS! It wasn't that they never spawned, it was that they were taken out by my friends, who were dealing all the damage while I was healing them. This is a BIG oversight as this quest is supposed to be completed in a group! If one person in your group completes the objective, why doesn't it register as being completed for everyone in the group? You guys have to fix this! I can't solo this dungeon so I need teammates, and I'm the only templar so I have to focus on healing everyone! I can't complete this quest because you guys have made it awkward as -BLAM!- to do!!!!
