Guild Wars 2

I was part of a party attempting to complete the Ascalonian Catacombs dungeon on explorable mode tonight. We took the first path, the one which pits you against the [spoiler=graveling patriarch] Howling King[/spoiler]. It was a full party of five (human guardian, charr elementalist, norn ranger, sylvari ranger, and sylvari necromancer), and we managed to get up to the final boss of the dungeon, and defeated him along with the crowd of minor enemies that are in the area along with him.

When we defeated this boss, our dungeon objective did not update, no chest was spawned, and the NPC who was traveling alongside us did not have any new dialogue or actions triggered. Our party was presented with an empty arena. At first, we suspected that we had perhaps not killed enough of the secondary mobs prior to this boss, so we entered several side areas and killed all of the mobs there, to no avail. After a while spent with no results or change to the dungeon objective, we broke up the party and left the dungeon with no reward.
