Recently returned to Destiny for the first time since Echoes, and when i attempted my 4th iron banner match, I was met with a watercress error. The issue is that ever since this error, my warlock no longer has the multistep challenge for rank up and memento drop boost, even though I should be on step 2 of 4. Not sure what to do, as I'd really like the boosts, but don't understand why my challenge just disappeared
