I cannot pass level 251 on alpha Betty. Game has 42 squares to spread the cheese, there are only 41.  Mistake on games creator. I spread the cheese on all 41 squares 3 different times and could not pass the level because the game says there are 42. I can't go any further until this is corrected. What do I do?
