So I was trying to advance another game I play while I still had Cookie Clicker open and changed the date ahead a year. I then reset the date to the correct date and time. I got all the achievements I needed on the other game, but when I came back to Cookie Clicker's window, it now shows that the next sugar lump won't be mature for 307 days. Is there anyway to fix this? Or did I just screw up the sugar lumps for my game?
