ai campaign infiltrate the convention

because of the impending fix to campaigns I figured I'd better actually finish the ai campaign because I didn't want to lose any boons. so while doing this quest I gathered the parts and items for mella gave them to her and then the quest disappeared. couldn't go any further with it. I looked thru my open quests (which is kind of difficult because ai doesn't have it's own section you have to sort thru general and pe quests... but I don't see it anywhere. I tried just going to the next part over by grazilax but it's not there.

I actually have the same situation on my hr so before going to do that one i went looking for the actual quest. I can't find it at all even though i have it and I got the beholder thing in the basement and its available to get on the airship... I haven't tried doing that quest yet on this toon. but it's weird I can't find the quest anywhere.

I did it on my hr and it directed me to grazilax which I'd forgotten i have to talk to him but since the quest went away it wasn't directing me there and it wasn't clear I needed to talk to him. confusing if you don't know the quest by heart.

where is the quest kept?
