[GAMEPLAY] messed up projectiles/auto attacks, Brand ults on AA etc.

Just had one of the wildest games in my League time. Everyone had messed up auto attacks! Not just visually, but also gameplay-wise. Brand's auto attacks were brand ults, TF had a red card on every auto attack, Vayne's auto attacks were all condemns. And mine... Well, mine was probably the strangest. I could infinitely make turrets on top of every creep/enemy champion as Azir, and the passive would only go on cooldown when a turret broke down.

It was a custom game which I randomly joined on a whim, because I felt like a short game before logging off. It was on the Howling Abyss, and was not an ARAM.

I think that either: it was serverside and something was seriously messed up in the packets being exchanged from client to server. Or: one of the players in-game was hacking all of the projectiles.

No clue which one, but it was seriously insane. I'm not sure if I'll ever get this bug or will ever be able to reproduce it. And sadly, I don't have proof on it.
