Hey, love the game, only managed to play it a little while today, and I have linked it to my Rock Band World too, but I'm having trouble with score wars.
My actual problem is that on the app, it says I have two score wars, but in-game I have no messages about them. I have played the song required(seven Nation Army, in this case) but in the app it hasn't updated with my score. Also, in the game, I have managed to send a score war against a random person, but only through the recommendations, is there any way to send them to friends through the game? I know you can do so through the facebook app.
Another awesome harmonix game, gonna have to juggle this one with learning pro guitar.
