[Gameplay] Aurelion Sol can be seen anywhere on the map.

When Aurelion Sol dies AS HE IS CASTING ANY OF HIS SPELLS he will become visible to the enemy team no matter where he is on the mini map. The enemy team will be able to continue seeing him until he dies again. This bug only grants vision on Aurelion Sol, not the areas around him like a blue trinket. This only happens to one person though. I got it while playing Kog'Maw in Normal 5v5 Summoners Rift Blind Pick.
