Guild Wars 2

I’ve gone through this twice now with the qualifier still active after beating Togonn Windmane, and it hasn’t counted. I went in with a party, and they all got the achievement just fine.

In the screenshot that I took, you can see I still have the little buff, and this screenshot was taken at the very end of the instance next to the cave. Is there any way I can be rewarded the achievement without having to repeat this instance all over again? This achievement has caused me and my party a lot of stress, and it was all for nothing.

Edit: We decided to give it one more try and I managed to get it. Turns out you have to damage him for it to count, I spent all my time just avoiding his attacks that I never actually hit him. Feel free to delete this thread.
