[GAMEPLAY] Aurelion Sol Bug Ult Reset?

There is a bug when Aurelion Sol ults when he is about to die, and the ult goes off. However, the ult resets causing the damage to be dealt, but the ult cooldown resets. I have had this happen to me twice and it was over a span of my first eight games. I did not intend to find this bug, but I believe it is game changing. This is how to do it. (Sorry I do not have a screenshot)

1. Have a champion kill Aurelion Sol
2. When Aurelion Sol is about to die, ult
3. The ult will go off but the cooldown will reset and can only be seen by some teammates

I hope you guys can pull through on this one like you always do Riot! Sincerely, Yi 2 Challenger
