I love this game. HOWEVER. In the last several days, when I have cleared a level, the screen goes black..I have to go back into the game because it shuts off, and I have to do the SAME level all over again. Not only that, but I had purchased SEVERAL HOURS of play , which is not cheap, and I lost OVER HALF of my hours ?!! They just disappeared..THEN I earned free hours of free play, and THAT disappeared.Come on guys. This is discouraging and not fair.
