Dirty Job: Demolition Detail/Dirty Job: Wood Work

[Crystalinn-aerie-peak (Crystalinn)]

There’s a larger thread open for this irritation:

World Quest "Dirty Job: Demolition Detail" is bugged

Apparently it doesnt even work unless you do the side-quest pre-requisite (your character will simply not pick up the dredger no matter how many times you click), as well as there being no credit given for completing the demolition tasks sometimes, and the mobs spawning out of nowhere giving you very little time to protect the dredger-buddy. Really poorly designed and raw.
