Cho'Gath Ult Bug

I don't know if this is occurs on all maps, but on the Howling Abyss Map in ARAM, there was a bug with Cho'Gath's ult that occurred. What happened was that the moment he died, if he ulted in the exact instance just before he died, then the attack would still hit, but the cooldown would not activate and the skill could be used again immediately after respawning.

I also attached the Game Log file of that match, if this helps any.
