Movement System Rework

  • Player hitbox now updates continuously for all movement states.

  • The following abilities still deal damage and apply debuffs to leaping champions: Billy's Nothung (E), BMO's Game Frame (W), Choose Goose's Electric Charge (Q), Cinnamon Bun's Ring of Frosting (E), Flame Princess's Scatter Fire (Passive), and Ice King's Hailstorm (W).
