Guild Wars 2

Just tried to do this achievement. I am 100% certain I didn’t trigger any traps. Talked to Kasmeer and didn’t get the achievement. I went back through to check if I had triggered any of the invisible ones but I hadn’t. Did you get this matter resolved?

Just encountered this problem. I didn’t attack any of the risen before the bone wall turned up. The first 6 risen all have the buff that makes them invulnerable, so I can’t progress any further. Tried starting again multiple times and no luck…
