User blog comment:Sagee Prime/Champions bugs!!! What are they? I must know!!!/@comment-3213322-20110404140811

Alistar:
 * Pulverize occasionally rockets the enemy out of the world screen for something~4 seconds.
 * Poor design more than a bug, but Headbutt direction seems to be determined by combining the vector of the target's movement to the headbutt direction.
 * Occasionally Headbutt does no damage and does not knockback on impact.

Urgot
 * Hyper-Kinetic Position Reverser occasionally fails to switch places (without being interrupted or debuffed).
 * Manamune does not add bonus AD to damage from Noxian Corrosive Charge
