Not sure if this is the right place to post this!
I was playing "Jack and the Harlots" (RBN), in RB3, and i noticed that the hand animation for the slide at the beginning of the song is NOT ok, you can see how the hand jumps from the body to the nut!... if you see the same part in RB2 you can see the real animation i mean.. the hand goes smoothly.
Also i noticed some issues with the idle states.
Feel free to download the preview of the song and take a look in RB2 and RB3, also check all your charted songs just in case.
Any of you having similar issues?
