Bug description:
If you played online and you are NOT the host of the match, your controller button mapping was paired to your Player 2 controls. This would result in the player being forced to play using the default button mapping even if you had re-mapped your Player 1 controls. The workaround was to have a second controller plugged in and to re-map those controls.
This bug has been fixed and both hosting player and non-hosting player's controls will reflect the controls that have been mapped to one's Player 1 configuration.
If you find any other issues, please report them here.
