I think there may be something going on with the epilogue resolution of the Jiyel personal plot? When I played through it I successfully cured myself, chose to seek justice, got the achievement, and saw every possible scene, but there was no reference to it in the epilogue - I just got a weird interlude that ended with "You couldn't help feeling like you had missed out on something important". Is there some final, invisible skill check or is it just bugged?
