Me and my friends are having a problem while playing coop terrorist hunt.
Either one of us, or all of us exept the host loses the connection. We then end up in the main game menu and the "This game session is no longer available" text appears.
Then the host must re-invite, and we may continue playing. This may happen 2 or 3 times in one game.
As I write, I lose the connection to my friend in the other end, even thoug we where just chatting in the game lobby.
This is for PS3.
The NAT is 2 by the way.
