Supercell, I have been playing this game since it came out. Its definitely my favourite game no doubt. But, I just purchased gems for a legendary chest and got miner. And now it says I have -500 gems!! Please help, Ill have to work my way all the way back to positives or pay my way out of it. Which just seems like this game is asking for money. Help me!?
