Now that I have GH3, I just leave one Wiimote in there all the time and just disconnect/reconnect the Wiimotes when I want to use the guitar. But now I'm having problems with the Wiimote in the guitar randomly disconnecting. I'll get the guitar Wiimote all connected up and then go into GH3. But as soon as the game starts, the guitar Wiimote disconnects and the other Wiimote is then connected as the first controller. This also always happens when I go back to the home menu after finishing playing GH3. I've had this happen at other random times a few times as well.
What's going on?
