this is the second time i had an error. after clicking on a dude to kick the ball for street soccer, it says something like nullpointer and then i click on my games and theres 0/0 when i know i have 32 games.i refreshed and its back to normal.

This is a well known minor bug. It happnes from time to time, but as you have noticed you are out of the problems by refreshing the page.

A bit inconvinient, but rather rare so you can live with it.
