Ok so this has been driving me crazy. I have unlocked and fully researched PoA rank 4 in my sanctum, but I am unable to progress past the trial of loyalty on the first four memories, and I am unable to progress past the trial of courage on the other six memories. The selection screen just says I need to defeat more bosses to unlock the next difficulty tier.
I have done all possible quests, I have crafted all the equipment available to me. I have defeated all ten memories numerous times on all three of my soulbinds. I have never dropped or switched my covenant. Nothing I try will unlock the next difficulty tier. Is there a counter for how many bosses I need to defeat? Am I just bugged? Any help would be greatly appreciated.
