What's the problem with the whole invite system?
-If I send an invite, my friend often doesn't get it and visa versa.
-If I accept an invite, it makes me leave my current game and then tells me 'game no longer exists', even though I know for a fact my friend is still in the game I'm trying to get to.
-After we both get online, it can take as long as half an hour for my friend to appear on my friend list for inviting, and visa versa.
-Sometimes he is on my list but I'm not on his and visa versa.
Why does this happen?
