Lost in Random - Unable to progress

I spent 15 hours playing Lost in Random. Then after a fight my game glitched and I am now unable to progress further because the game is not aware of where in the storyline I am and I cannot get back to where it thinks I am.

I am stuck now because the game does not have chapter selection or any way to get back to a previous checkpoint.

More details about the glitch: I had a fight in sixtopia but the game said it was over before it was so I threw dicey after the fight was technically over. I got stuck in the dicemention so after the game saved I went to main menu and restarted my game, but after that the game thought I had just arrived at sixtopia instead of knowing I had already been there for roughly 15 minutes.
