Graves Auto Atttack Bug

Every once in a while if you are attack moving Graves' auto attack will get stuck and not fire. To get out of it you have to normal move a bit then you can attack move again.

This has happened multiple times, I don't know how to trigger it for sure. One thing I can test next time I play is if it is when he is in a very crowded area (lots of minions and/or players.)

P.S. I'm certain it wasn't just the new reload function.

P.P.S. I think the Graves update is fantastic, he's a lot more fun to play - thanks for that!
