headhunter alkali bug

Recently I brought a headhunter akali skin but when I use it in game, her Q seems to have a delay on the animation of the mark and activating the mark by auto and it is a huge bug for such an one shot champ with a delay. Hope that Riot can fix it cause headhunter akali is the best skin for her but but due to the bug I had to refund it for blood moon akali.
