The game use to be very smooth and reliable, now it has constant errors with the network ever since they added watching videos to get more picks after a match. Game will error out after matches because of this network glitch, you will lose picks that you won in the match. Unable to use them and makes it even worse since it happens all the time in events. Putting you at an even lower chance of completing the events they have.
