This is the reason i'm thinking of stop playing the game.
When you don't add skill points, for example when you have a player with 149.8 level, so just before he go to another level, some players give a lot of money and tokens for that player.
Now Top Eleven adds the skill points automatic and after that the players are worth nothing anymore and you can't sell them because nobody wants them. So ending their contract is the only way but costs you a lot of money.
I allready deleded the app on my Phone, which i thought was the problem but it stays the same.
