[Gameplay] New HUD level up artifact

Whenever a champion levels up a small artifact will be left behind as seen on screenshots. As far as I can see it doesn't matter which champion it is, although didn't try them all. Changes made to the HUD remove the artifact until next level up. Recalling removes it because it ads the countdown bar, resealing your HUD in options also does it. You can just move your slider at any direction and back and it will clear it. Reproducing the bug should be easy, since it was there ever since the HUD was updated. Artifact is located above the inventory. It looks like a bunch of ability level up arrows stacked together. On first screenshot you can see the artifact, on second it is not there, it was removed by rescaling and then returning HUD to 50% size in options. On third artifact is back after another level up, and on 4th it is removed by using recall.
