Ankylosaurus Knockback Immunity Triggers Cooldown On Dino Despawn

When playing as Ankylosaurus and activating the Rushed Stride buff while crouching, if you despawn the dinosaur without receiving any knockback attacks, the knockback immunity effect will still enter cooldown.
The knockback immunity should only consume its effect and start cooldown after being hit by an attack that causes knockback. Despawning the dinosaur should not trigger the cooldown if the immunity has never been activated.

After despawning the Ankylosaurus while the Rushed Stride buff is active and no knockback attack has been received, the knockback immunity ability goes into cooldown automatically, even though the immunity was never triggered or consumed.

The knockback immunity should only enter cooldown when the Ankylosaurus actually gets hit by an attack that applies knockback. Despawning the dinosaur should not trigger the cooldown if immunity remains unused.
