I seem to have run into a problem that I cannot finish the 3rd mission in Ares campaign as Arabian trucks have probably broken pathfinding as after a few runs from the orange warehouse to the NW corner they just sit there with full cargo and nothing happening. Did I ♥♥♥♥ something up, like accidentaly barraging their route so it got broken with those few tricycles and captured American cargo bays from the convoys?

Also, how are you supposed to defend that hill with just two bunkers and an armory on a damn bad place?
