In battles... the current attacker [displayed in the circle on the left] goes out of sync with the list of attackers on the right.
You'll click to attack the enemy and nothing happens.... the attacker in the circle on the lower left will change or advance, but the lower right list of attackers will not correspond with your attacker or the enemy you're attacking.... sometimes the current attacker will show up 3 or 4 placements down the list on the lower right.... then I'll reload the game and everything's ok for about 2 or 3 attacks, then it goes out of whack again and the game needs to be reloaded again to fix this out of sync issue.
