Graves Smoke Screen bug (gameplay) with replay.gg

There is a bug where graves smokescreen doesn't fully go through, the damage and smoke canister doesn't appear on the ground. There is a brief animation of casting the ability this appear during this gameplay exactly at 30.59 and the cooldown is reset. Not sure how this happened.
