Guild Wars 2

Proximity Test: Megadestroyer
I wildly run around while clicking on my generator but nothing happened. after leaving the area, the achievement was mysteriously there.

Proximity Test: Goemm’s Lab
This one does not work at all. Defeating Goemm several times, running around while clicking on the Synergetic Generator, nothing happens. Not at the chest or at the death position of Goemm.

anyone else got those problems?

edit: never mind, I got the Goemm’s Lab Proximity test. The chest was invisible, because of auto-loot. Found it near Goemm. (in the direction where you come from, near that wall in the middle)

Goemm’s chest actually appears elsewhere, but you need to use the generator at Goemm’s position. Legitimate bug.

Obviously you got the Megadestroyer one the proper way. I expect you just didn’t see it :/
