I would like to expand at level 50 and earn more then 220,000,000. First problem, Every time I reach level 50, the game recognizes the level, then it drops right before my eyes to level 48. I continue to work through the game, reach level 50 again and again and each time it drops me to 48. This has happened 4 times. Second problem, the game drops me to 200,000,000 each time I reach 220,000,000. I have been unable to earn more coins. This has happened more then 9 times.
