I reloaded several times to try again, but it still happens. I play it through the itch.io game manager
It's unfortunately not an error I can fix right now, but I do have some ideas how to circumvent it in the future. If you come across it, try pressing F5 so that the game reloads without closing the game, it should hopefully skip it this time. Make sure you're not running anything else either that slows down your RAM.
