[GAMEPLAY] Shifting auto-attack focus with Nasus Q slows auto animation

Shifting target of Nasus' Q during animation causes his second animation to be very slow, effectively stunning him for the duration. Once the auto-attack lands, his speed return to normal.

1. Activate Nasus Q
2. Select a target to auto-attack
3. During animation before hit, select a new target

This bug occurs on every attempt I have made.
