Whenever I try to break an oak wood plank it freezes the game. I was trying to break an oak wood plank to get to my secret hidden chest. I expected it to break normally so I could check to see if I have any diamonds. Instead when I broke it, it froze my game! I couldn't even access my pause menu! The only way to get back into Minecraft is to clear the app and go back on. I even tried restarting my iPad and it still didn't work! If you could fix this I would be very grateful. By the way I am playing on 1. 1.2. Thanks!
