[GAMEPLAY] Caitlyn ulti sometimes not resetting when target dies before cast is complete...

I was maybe halfway through an ulti cast on Graves on ARAM when my team killed him, no bullet fired, ulti went on full CD...

according to wiki:

Ace in the Hole will be canceled and put on a 5-second cooldown (but not refund the mana cost) if the target dies or becomes untargetable during the channel.
