I get your invites mate but when I try and join you's are obviously mid battle so it just says can't connect so I don't wait in case you don't send another when you're finished your game. I'd send one back but I'd be in a game if you accepted and it wouldn't connect. Unless someone does what Dave did and send out invites and just wait for folk for 5 mins then we'll be sending invites and not getting any games together lol
