I completed the legend campaign on my titan and then on my hunter. On my hunter I had not completed Lightfall yet and had not unlocked strand. When I completed the Final Shape campaign I proceeded to complete the 4 adventures in the Lost City to finish unlocking prismatic. I noticed an issue after completing The Hollow parts 1 and 2 when nothing was unlocked. I replayed them multiple times and now after completing legend Lightfall and completing the adventures again nothing in unlocked. No reward is shown available at the adventures after completing them once.
