This little patch fixes the bug where marbles were disappearing in the middle of the field. It's honestly crazy that this somehow got through all my testing. Anyway, keep enjoying the game and keep reporting bugs to me!
I'm still looking into a bug with the "refund all" button not refunding. If anyone has a save file where this happens to you, please send it over to [email protected] and I'll keep trying to fix it. Thanks and have fun!
