Guild Wars 2

I noticed this in the last part of the Claw Island bit and in “The Battle of Fort Trinity”.
I’m not sure about the Claw Island bit, but in the Fort Trinity bit i started getting xp and then after I saved the loggers it just stopped.
I’m using a Birthday booster, but I don’t think that should resutl in me not getting any xp from killing things.

I upgraded them yesterday

I just want to start by saying that my computer cost about 3,600 USD, is gaming optimized and works perfectly with everything i’ve thrown at it. Except GW2.
When in GW2 it crashes somewhere between 5 min to 2 hours, more often if I use a waypoint or a portal, but sometimes seemingly at random.
I have the latest uppgrades for my graphics card and my motherboard.

I feel pretty cheated since this still is a problem and it’s ONLY in GW2 I experience this.
