Was just looking at the old 2018 Solstice of Heroes armour and the parts I didn't complete the Masterwork objectives for, ie. the helmet (Complete the Nightfall Prestige at or above the bonus level), the gauntlets (Complete 5 strikes with at least one clanmate) and the chest armour (Complete the "Leviathan" raid on Prestige difficulty). Does anyone know if you can still equip those items now and complete the objectives to unlock the Masterworks on them?
Did you ever try to complete your missing 2018 Solstice armor masterworks? I have just completed my first Leviathan prestige raid and there does not appear to be an option to masterwork the hunter Solstice Vest (Resplendent) even though I have now obtained the prestige raid emblem :( Admittedly I wasn't wearing the Solstice chest piece at the time but I didn't think that would matter as from memory you did not have to be wearing the other armor pieces on completing their masterwork conditions. It looks like my memory may have failed me and I needed to be wearing the chest piece on raid completion but if none of the other masterworks can be completed now either I will give up on a second attempt.
