[Gameplay] Aurelion Sol Passive visibility Bug

I played a game of ARAM yesterday against an Aurelion Sol and had a bug occuring to me. I communicated that in ALL chat but since none of my teammates said anything about it, I presume that I'm the only one having that bug.

Everytime Aurelion Sol's orbiting stars touched a bush or touched the unplayable area of the map (outside the map), there was a chance that 2 of his 3 irbiting stars went invisible. There was ALWAYS at least one star visible at any, but the other two always disappeared together.
