The problem connects the CONTROLS HOTKEYS and ISSUING MOVEMENT ORDERS as a vehicle commander.
ISSUE: the player as a vehicle commander is not able to issue movement orders to the driver.
1- If the player uses one of the DEFAULT CONFIGURATION, no issue occurs.
2- if the player changes the controls of the 4 directions of vehicle movement (forward/back/left/right, by default WASD) to something else (like TFGH or IKJL or ESDF ecc.) the issue occur:
The player as a vehicle commander won't be able to issue movement orders to the driver.
However the player will still be able to issue movement orders with the old hotkeys WASD (even if they are not there anymore, because they have been changed)
3 - if the player chooses the EMPTY PRESET (to start from scratch) no matter what hotkeys he chooses for the vehicle/infantry movement. He won't be able to issue movement orders to the driver, even if he chooses the old default keys (WASD)
