Guild Wars 2

Based on the requirements given to us by the devs for this achievement it must be bugged. I have completed the requirements on 4 separate occasions and have never gotten credit. In my last run I never even got hit by a single cannon shot nor took damage from any ground aoe during the cannon phase nor immediately after it. I’ve but an obscene number of hours into running this dungeon for this one achievement and this is costing me my sanity.

Can confirm this. Two thieves sat in a corner chain stealthing each other while us three ran around the other side of the room. The cannons never targeted the thieves and neither ever took damage. Can we get a clarification on this achievment. It’s either bugged or there are other requirements that have not been made known.
