Sorry to be a bother because I know itch dropped support and you probably don't want to spend much time fixing bugs on here anymore, but I downloaded the new free update days 1-17 (I previously bought the 1-16 Elysium edition) and decided to play through entire game again. I got all the way to day 15 and right as the laptop scene was supposed to start this error popped up. 
If you are able to guide me to a fix that would be awesome, but if not I totally understand. I hate that itch is doing this to so many wonderful creators such as yourself. No matter the outcome, I wish you nothing but success. Thank you again.
