Guess that explains a similar bug I have. Been progressing Talia and Yumi. I meet Talia on the balcony at night, go and talk to/kiss Yumi, and then immediately get dumped out to the main menu.
*Edit: Weirdly, progressing other story lines and then trying again on the balcony has resulted getting past that particular bug. Very odd. I'm sure it's a nightmare to track down and fix permanently if it is such a hit-or-miss thing to trigger.
*Edit 2: Just hit another loop bug I guess. Been interacting with the cashier and suddenly no longer named Cashier, but Abby in 2 interactions. Then I try to progress Emma's story and pick up the book sequel where I actually learn the cashier's name is Abby, and it crashes to main menu at the end of the interaction. I was really hoping to not have to start from scratch, but I guess I will have to if I want to enjoy without hitting these weird continuity issues/bugs.
*Edit the 3rd: Just tried a from-scratch playthrough. This time when I go to get the spaghetti westerns from the shop, I get dumped to main menu. This is admittedly somewhat of a speed run attempting to get back to where I was in the story. It seems like several shop interaction scenes end with bugs/getting dumped to main menu from my playthrough attempts this morning. If a save game or anything would help you troubleshoot, let me know. This won't deter me from playing the game, just means I have to go through and more carefully pick and choose which story lines I need to advance I guess.
*Edit the 4th: Since this seems to be a known issue, putting in my 2 cents to request cleaning up the dependencies in the code before adding more content. But I know that's not a popular opinion.
