The wording in the Bungie Help post seems to have changed 43 minutes ago. It seems to imply we may get to do the quest again. Patrol stuff is lost which is fine but Faction Quests we may have another shot at. Here is the new wording on the help post [quote]• We're aware of an issue where Patrols and Faction-specific Quests are not granting the expected rewards upon completion. These rewards will be granted as expected for these activities starting on 9/15/2015. Patrols completed before this time will not retroactively grant rewards. Faction-specific Quests will be able to be completed at a later date.[/quote] So it is goodish news. Sucks it happened but at least people may not be screwed over.
