(GAMEPLAY GLITCH AURELION SOL ULT SHOWS NO COOLDOWN)

(GAMEPLAY BUG WITH AURELION SOL)

With Aurelion Sol, my first game with him I found a bug. So when I was about to die I fired my Q and then right after my Ult, (with me using my Ult right as I died, almost simultaneously) and when I respawned, my Ult showed I had no cooldown and could use it again. It would let me aim it with the marker like it was ready, click it again to use it (even though it wouldn't fire) and it would make the sound effect of me firing it (even though Aurelion Sol wouldn't do the firing animation, or use it) and I tried to ping the remaining cooldown on it, which worked and showed it was on cooldown even though it would let me press R to aim it and press R again to fire it. I was killed by a Bard with an Udyr getting the assist, and I had a Rod of Ages and sorcerer's shoes... If thats important at all. This was on 5 v 5 Summoners Rift.
