I ran into this bug. I had played the game through once, then sacrificed myself to save the world. I played it again and got stuck where QPernikiss needs a full memory album. The problem is that this time I had not gone on all 4 date types with Cassie, Karma and Sutra because this isn't required to reach this point. However, I could see the dates in my memory album from my first time through the game. To satisfy QPernikiss's full memory album requirement go on all four date types with Karma and Sutra and go on the two date types in the middle with Cassie.
