[GAMEPLAY] Jarvan IV's auto's doesn't display properly, and doesn't always go off.

**OBS: I'm trying to reproduce it, since I missed that part. If I manage to, video proof will be comming up as well. **

I was playing Jarvan IV just recently, and from the very start, I noticed that his auto's doesn't always go off visually, and sometimes they won't even register at all.

The events that took place before the bug appeared: 1: I bought a Hunters Machete, 2 Health potions and a Vision trinket. Summoner spells was Smite and Flash. 2: I start with the Gromp (I was red side btw). First ability was E, and I used smite on the Gromp immideatly before using E on it. I also used 1 HP potion. 3: I picked my Q ability when I hit level 2. Then went down to botlane, flashed in for a kill, then died to the turret a while after, while trying to go for 1 more. 4: Then I bought the Rangers Trailblazer, and 2 more Health Potions. I went down to kill the Blue buff. 5: From here on, Jarvan's auto attacks didn't display properly, and sometimes didn't register.

I was using his default skin.

I hope the event list could be helpful in discovering what's wrong.

Thank you!
