Gameplay Bug with ZED Shadow

While I was playing zed in a bot game and I would use his shadow attack after the shadow disappeared you still can attack with his shadow for at lest a sec AFTER ITS GONE.

Steps

1. Use zeds shadow attack (his w) 2.Use any attack so his shadow also attacks 3.shadow will disappear 4.Use another attack (the shadow will act like its still there and attack)

It will happen every time.
