In a battle with 8 of my units against 6 brigands, I get to a point in the second round of attacking where 2 of my units still have attack points (moves) left, but the game won't allow me to attack either of the 2 remaining brigands, and if I hit the next turn button nothing happens. One oddity I noticed is that one of the remaining brigands has 0 hit points but is apparently still alive:

The only way out of the battle is to hit the auto-resolve button. Sorry I can't post a saved game, but the game won't allow me to save in the middle of a battle.
