Xbox version ignores all controller input if copilot status changes

If a copilot controller is connected or disconnects during play, all input from all connected controllers is ignored.

Steps to reproduce:

EITHER start playing with one controller, then connect a controller that has already been set as a copilot
OR start playing with 2 controllers then set one as a copilot
OR start playing with 2 controllers set as a copilot pair, then disconnect one controller.
