Why did this not count when I did one of these events in WvW where I used powder kegs? For me it added one to “kill with mortars” and that achievement. That is strange. Shouldn’t it update the demolitionist then?
Edit: To be precise: It was the event at EB, ogre camp. And I used a lot of powder kegs. Might be just a bug at this single event if no others report it from other events and ther correctly getting the demolitionist.
