yesterday i submit 2 games. Each game was valued for 20 coins so it should be value 40$. But now my value is 30$ and it must to be over 60 bcuz long time ago i was submited 2 more games. So yesterday my value was something about 25$ and when i submit 2 games (both for 40$) i must to have over 60$ not 30...
