My Sylvari chose Pellam for Trading Trickery, after I hide the Hylek, the story does not advance anymore. Pellam shoots the flare to alert the Dengatl but they never spawn. I cannot complete my Storyline quest. Please help, thanks.
From what we can tell, this particular bug only seems to come up in group story; are you doing this with other players? If you just want to continue your story, doing it solo should allow you to progress.
That being said, we also have a fix for the group story issue in the pipeline. Thank you for your patience!
