I believe the game crashed on the phrase "this place, it looks familiar again". At this time I was trying to pull up the menu using the escape key. I managed to play up to where it crashed so no need to worry about the save. Hope this helps somewhat

Hello Crealdew, sorry again for the crashing issue.
From what I was able to deduce, there's nothing at that part of the game that could make it crash, my take is that the engine randomly crashed.
Now, however, I am still working on why the save file got corrupted.
I hope you'll still be able to enjoy the rest of the game if you have the heart to replay and I'm deeply sorry your immersion was ruined.
Thank you for reporting that and I hope to be able to fix it!
