Sorry to insist, but isn`t there any solution for this problem?
You can quite surely reproduce this bug, if you swap some units twice.
As you can see, the connection of this unit is no longer shown by that green circle, and mostly the morale fell.
The auto-assist doesn`t help, because it seems not to work in the opponents turn, and the advice of the Duke of York only helps in the beginning of the turn.
Since i know you already tried to correct this in the first bugfix, it shouldn`t be such a huge problem to finish this fantastic game.
