Started the New Light Campaign so I could get the Saint-14 mission to be able to do Iron Banner. Got to about halfway through the New Light campaign and now it is gone; can't see any quests for next steps nor is it in the Archive Terminal in the Tower; it just disappeared? I believe according to videos on the walkthrough I should be at the "Learning Light" quest. Did the game bug out or am I missing something to kick the campaign questline to continue? Thanks.
