When you have a connection set up with the Kinect event, unplug the Kinect, then plug it back in and attempt to turn your connection on, Mayhem will a) not turn the connection on and b) give you the "No Kinect Attached" error message in the error log, despite the fact that it is definitely present once again.

NOTE This will continue to be the case until you close and reopen Mayhem as a whole; even deleting and creating an entirely new connection will not rectify the problem

EXTRA NOTE also, "Attached" should not be capitalized in the error message :p
