Rek'sai makes people fly

So me and my friend were playing aram when i got Rek'sai and the enemy team had a Warwick. The bug occurred twice in which i would knock Warwick up like .5 seconds after his ult started and he would fly to the moon and back. I'm not sure that this really impacts the game but my friends and I found it quite funny, i also did this to the enemy Jax when he used leap strike on me.
