[GAMEPLAY] Warring Kingdoms Jarvan IV autoattack animation bug

Played a game as Jarvan IV with Warring Kingdoms skin. Not sure if skin is actually relevant to the issue or not. When autoattacking, be it minions, champions, turrets, anything at all, the autoattack animation wouldn't play 80% of the time. Opponent reported not seeing it as well, said I was getting stuck in the animation and skating around. Damage would be dealt despite the animation partly or not at all playing. Little to no gameplay impact, save for a possible issue with his passive. Seemed like my passive wasn't procing consistently on the first auto - could tell by damage numbers and sound. A few times I autoed full-health minions, didn't hear the passive proc, and dealt the same amount of damage on every hit until it died.

Only played the one game where I saw it happening, so can't say anything as to frequency. Wouldn't be bothering to report if enemy team hadn't seen it as well. Did not see the issue at all across the last however many J4 games I've played with this skin, only this most recent one.
