I have 9/10 pages of Beneath the Endless Night. I've completed the entire season questline as well as the epilogue. I was unaware of a cutscene after the final mission and exited out after completing before it played. I have tried replaying the mission and staying but have not gotten the cutscene or the final lore book and secret triumph associated with it. Did I mess up the questline? Have I misunderstood where the last lore book is? Or is it just bugged?
