I tried to set up three AAA vehicles that player can drive but for some reason they cannot move. They are AAA bofors 40mm, AAA M1 37mm, and the AAA M45 Quadrant HB 12.7mm.
They are player can drive is selected and it shows the gear is neutral along with a symbol of an engine on the right side of the screen. The engine cannot be started with the LCtrl+E as shown in the default and the gear cannot be advance with the "X" key as in the default.
Any suggestion of where to look or how to correct this?
