I have the same problem with returning to the home screen exactly that moment - must be a bug right? The gallery is fine though. I'm still running version 12.

I made this account specifically to tell you the issue; what happened was that Persona's accidentally released some 0.13 events (anything past the park event with Sora) in the 0.12 update. So the reason you are cut to the main menu is because those events are not meant to be there, and, therefore, weren't coded to have a proper transition from the game to the main menu. Hope this clears things up!
