I can't seem to acquire some of the weapon essences apart from the fusion rifle and machinegun. I visited the lectern to see if I could get a bit of a head start to farming these weapons when they hit next week. Text displays that I could only have one essence at a time but I don't see the quest associated with them on all of my quests tab. The only exception is with the fusion rifle and machinegun. I think it has something to do with all the changes that happened recently because I specifically remember not deleting those quests. I hope this would be addressed soon if it's not just me not remembering how the lectern worked. Also, can we have more vex to kill on the moon. Some of the objectives are to kill vex but the issue is that vex are rare after the vex invasion was gone.
