Guild Wars 2

After finding the charr in the cage, and prompted to “Find Queen Jennah” the party gets an attempt to nail it, but if the party were to fail and get defeated, the enemies would reset to their normal positions, turn to “allies” (green) and the mission would freeze. The only way to fix it is to go back to the cage where the charr was by the tree and “interact” with the cage, making it close and open again; however, sometimes you would have to open/close the cage many times before it “sparks” the mission again, giving you the prompt to find the queen.

Not something that makes the party unable to finish the dungeon, but very irritating when trying to get through the dungeon in a timely manner.
