Maybe I need to look into this. Never heard of anything like that before. If you'd be so kind, maybe work that problem through with me, since I wanna get any bugs out.
So the game ends? Like forces you back to the main-menu without any error-message?
Does this happen in between any dialogue? Or on the mornings in the apartment? Because the only planned 'back to main-menu jump" would be on the still missing Xici-Event on day 49, giving players the choice to jump to the ending-screen or continue their game for free exploration.
