Every time I go on the app it takes forever to load it and when it dose, it starts being really lagy then crashes. Please fix I love this game and I would love if I could play it without it laging and crashing. Please fix soon If you do I will rate 5 stars thanks. Im playing on iPod touch 4th genoration.
