"The sounds "Perfect", "Amazing", "Excellent" and "Brilliant" were being played inappropriately. Due to a bug, they were never being played as they were intended to — but enabling the "correct" functionality caused them to be played after every turn where the total damage dealt from an exploding projectile was greater than 50% of the maximum damage possible from such an explosion, thus altering the gameplay too much. They have been currently completely disabled." The function is used in later games.
