MLB 15: The Show Online Play Weirdness and Crash 

This will happen if one or both users have a terrible connection. Chances are your opponents connection was poor. And I have a friend that has a terrible connection and we played two games online to both games I got kicked out with the same error messages you because we would see different things. Im sure it causes a desync and disconnect the game. But to be completely honest I've played over 40 games online between DD and regular head-to-head and I've been very pleased with the way online is this year.

I have seen this crap also.........

Do they even test this out before they release it? haha
