MP2 requires that each drone remain in its starting quadrant during the downdraft period. This suggests that each drone must start the match in the same quadrant as a hidden dig site of the same color.
The various images of the field setup throughout the game manual show each alliance's closed dig sites located in diagonally-opposite quadrants; i.e., one of the blue hidden dig sites is in a quadrant containing a blue cargo ship and the other blue hidden dig site is in a quadrant containing a red cargo ship.
The answer to Q&A777, regarding drones' starting locations, was that each drone starts the match in a cargo ship. In order to start in the same quadrant as a like-colored hidden dig site, this would mean that one of each alliance's drones starts the match in a same-colored cargo ship and the other starts the match in an opposite-colored cargo ship. Is this the case, or should the hidden dig sites each be located in the same quadrant as a like-colored cargo ship?
