I completed the quest requirements before, but turned in on the Nexus after, the main story line was completed. All Priority Ops, Allies and Relationships, and Heleus Assignments were completed and the only thing left are Additional Tasks. I turned in the quest, made my dialogue choice, and it completed. Check mark and all.
Maybe try turning in after you've finished the main story line and see if it works for any of you Pathfinders?

Just when you think all the glitches are cleared, bioware keep one in the chamber to kick you in the plums. Still glitched for me, even after patch 1.09.
I'm on the fully patched version (1.10) and this quest is still bugged for me...
I think I killed the big guy too quickly, and then had to wait for another wave of enemies to spawn - my final tally is showing as 24 out of 15 !!!
The optional task - to beat the best time - is still 'active', but I've been back to Voeld and the quest no longer triggers.
Am I still going to be stuck with this after everything else is completed?
I hate unfinished quests....
