In my game with Jeremy Good -- Hostage Chess game

I am having some difficulty transferring freed pieces during exchanges
from the grey prison area to free blue area. The system will allow the
player on move to drop a piece, but the opponent's freed piece will not
move to the blue area, even when attempted manually. As a result, pieces
do not appear available to the opponent, even when the
potentially-droppable piece is free.
