The reason ECC got dropped first game was more due to my ignorance than anything else I guess. What seem to happen is that the game freezes and you lose contact with the player who has taken a break. Game resumes once the player clicks "No" on his end.
I suppose you could say this is a bug, but it's not like you can exploit it really, as it "hurts" both the user and the receiver.
Neither can you force certain players to be dropped this way, like you could with a certain other program.
Though, I must say, I prefer the "old" way of just dropping gamespeed for some time.
