Well I was playing on Hard and I got to the Lou Guitar battle...I couldn't do it after multiple trys so I decided to go to training mode after I lost from the menu that comes up when you lose. Well it brought up the Guitar Battle Tutorial...That's not what I wanted so I exited and was back at the song and pressed retry. Well I start the song again and Lou is playing easy? Why is that...? I called my firend up and he tried it and it happenend to him too...not really a big problem, but could it be?
