Hm, that's strange. I just ran through that part again and it went through fine, and haven't gotten any other reports on that glitch. At which point did it occur? Right after saving (if so, is a save file generated)? Did the screen's colour go back to normal from the desaturated tint?
Since it's just a couple of minutes from the start, if you could run through that part again from the beginning and see if it happens again, that'd be very appreciated. Thanks for your time! c:
