Guild Wars 2

hello,
i wanted to do the challenge achievement and noticed that there is no challenge mote there. i watched some videos on youtube and if seems it should be at those stones next to marjory but it’s not there every time i open the instance. i finished the other achievements and also the instance, so that can’t be it. did the location of the mote change? am i missing something?

This is a bug. You can post in the bug forum, but by now it is known. I had the same problem and had to exit and re-enter the instance 8 times before it finally showed up.

Same happen to me. I solved it by playing with exit the game and log in, and also abandon the episode and turn it on again.
