visual bug.
causation: the move 'rollout'; when using the move 'rollout' (a five turn move if each hit is successful), if the user literally 'rolls' through xis enemies (single hit kill, such is likely as rollout gains damage for each successive hit) the pokeballs of the enemy are not rendered greyscaled. furthermore, if the target is the last pokemon of the opponent, the pokemon's graphic and health bar persists on the "win" screen.
How it currently is.
How it should be.
