Aurelion Sol ult bug, shoots backwards when clearly targeting forwards.

Sol has a bug with his ult where he casts it backwards from where you start casting it for some reason. I'm not sure what triggers it exactly, maybe mousing over the map quickly after firing the ult or when you're over a certain amount of movement speed. He'll start to cast it in one direction and then turn around and fire it completely backwards from where you indicated. I've actually lost a couple of games this way, probably have had it happen 7-8 times since I started playing Sol.

It's super annoying so I hope you guys can find / fix it.
