[GAMEPLAY] Graves bug - I can't hit Yoricks Mist Walker

I had this bug , where i couldn't hit Yoricks Mist Walkers as Graves. I don't know if it was because I used attackmove. This bug occured in a ranked game. It happend multiple times, the ones in the video are just some i found right away. It should be easy to recreate, since it happend quite often. The visual of warlords was there, but there was no damage.
