This is complete bullshit. I recently lost a game in Ultimate Dynasty that was to award me a 97+ dynasty player but instead "lost connection" to the EA servers because "I got signed out of PSN." So instead of a 97+ player, I was awarded 2,500 coins. Maddening.
Now they introduce a mode where we play four 6-minute quarters and we need to get tons of wins. I'm only in my third game and in the 24th minute, I again "lost connection" despite never have been signed out of PSN. This is utter bullshit. Get your stuff together EA.
