I just finished playing at table 283171622 and was going to report a bug, but maybe not. At one point I reduced a 3-figure tank unit to 1 figure, and a target appeared in its hex. A hint? Not sure. Toward the end of the game I did the same to another tank unit, and again the target appeared. And when I fired artillery at it, it rolled 3 dice instead of 2 (it was 4 hexes away, no special card used). What to make of that?
