In a recent game I had a couple of weird things occur and wondered if they were bugs.
1) Can't do a quarter turn at the edge of a map. I moved some med foot 2 squares to the edge of the map then went to turn the unit diagonally(to allow it to do a flank attack on the diagonal next turn) but could not click on the square (as it was at the edge of the map). So I was prevented from turning diagonally one square.
2) Fragmented troops charging.
I had a fragmented unit which won a combat and pursued the enemy. It then came into contact and charged that other unit. I didn't think fragged units could initiate combat if fragged.
