Guild Wars 2

So I am at the final quest (Finally!). But the Pact-group that is supposed to be going to the story quests location (The Dungeon – Arah FYI) aren’t moving. They are just standing at one location doing nothing. Well, except killing one or two risen running their way.

The only solution that I know of is chain-pulling mobs, killing all of the npc’s thus resulting in the event resetting. But there are too few mobs in the area for me to pull. And I am the only player around, so it is close to impossible for me to do. How am I supposed to complete the quest now? Please help me out here.

In the pictures below you will see where they are standing. They aren’t moving 1 inch.

I can confirm this, and several players ingame is aware too. I am looking to do the final (i believe) quest too
