Age of Discovery has messed up the ability to claim the Story Arc account rewards from the Recruit events.
I made three Delta recruits the first time you created that event, I completed and claimed all of the Story Arc unlocks on all three.
I made one Temporal Recruit, I still have the last two story arcs to complete (Delta Q & Future Proof), but have claimed the rewards for the rest.
Now I have claimed those rewards on most of my characters, but I have two that I haven't.
A Delta Recruit created during the rerun of the event, and an Age of Discovery character, the Story Arc Account rewards are grayed out to them both. Completing those "GTFO Wrapper" missions with my Temporal Recruit would appear to unlock the rewards for my Delta Recruit.
However the issue is with my Age of Discovery character as nothing I do is unlocking those rewards.
