I have noticed sometimes, especially with air units, they not only fail to respond to move commands but actually go in the opposite direction. Is it known what causes this or if there is a solution, besides literally always shift-g moving your air units?
See replay 19263189 at about 8:50. If you view from my perspective and hold shift to see the orders, I clearly give a move command to the north, but my inties fly in the opposite direction.
