Completed all of the steps for the Luna Calling. Went through the portal and offered Memory of Vell Tarlowe to Eris. Listened to her speak. When she finished I was prompted to open the chest. All I got was glimmer and a fragment. NO powerful reward! It is bugged. As I have lost a powerful reward towards my progression this week, I humbly ask you Bungie, for an extra powerful reward be given elsewhere in the game this week.
