BUG :: When having a maneuver equipped to quick slot, you can hold down the number and it will turn off and on at the speed of the frame rate.
Further Info :: This is no big issue with 'Guard', but if 'En Garde!' is active, since it plays a sound it will slow down the game a lot, causing a large lagg in movements, and the enabling and disabling can last for minutes depending on how long it was held down for.
Suggestion to fix :: Only enable or disable a maneuver if button is released.
