Guild Wars 2

I had to repeat this quest four times before completing it finally.

Each failed attempt I’ve had the following:

1st. Retake the Docks, all NPC’s despawn, leaving 40+ undead on the field for ME to die to.
2nd. Defend the Front Gate does not progress after the plague-bearer spawn.
3rd. Defend the Docks does not progress after the initial spawn once the ship arrives.

The fourth run, I defeated a sole white-named undead, and it triggered the final cutscene.

I hope you guys over in programming can get this sorted out.

The trick to this for anyone reading is to AoE all the mobs on the docks to “tag” them before they die from NPC attacks.
