Guild Wars 2

So I’ve been playing for a better part of the day with my brother, and we both went through skrittsburgh recently. One part of it is the world quest in the center of the city with the skill point above it. The quest requires that some large crab be defeated, except that the mob does not exist, or at least we cannot find it. It has been this way for at least 5 hours now, if not more.

I took a screenshot:

Hope this helps you guys out!

EDIT: I should add that one of my concerns is for people trying to use the waypoint to this area. As you can see, it is contested, and thus cannot be used.

This area still has a problem, i hope that developers are looking into this problem, I cannot move on in this area.

The Skrittsburgh tunnels/caves is the largest bug I have ran into in the game, along with that entire area. Needs some serious re-coding and fixing
