I don't know if call it a bug, but in the "Sixth world episode, Chapter 4 - Last battle" there was a cut scene where you get to see Ras waking up in the seven world, like an introduction to "Episode 1 - Chapter 1".

All good when you complete it the first time, but when you want to see it again in the Archive section, that scene is omited. I tought that maybe the scene was included in "Episode 1 - Chapter 1", but it drives you directly to a Vildred and Ras conversation (without context). Again, all of this is when you want to rewatch it in the Archive section
