[GAMEPLAY] Invisible Mundo Cleavers

So I don't have a video of this, but it's just as simple as it sounds. For the entity of the game, our whole team could not see a single cleaver that the enemy Mundo threw. He didn't seem to have any idea that this was happening, nor did his teammates say anything about it, so he at least could see his cleavers. Unclear if the rest of his team could or not.

He'd just throw one, and the animation would go off, when it hit, it effected us properly and hurt, but we just couldn't actually see them fly through the air haha. There didn't seem to be anything that effected it outside of the fact that the cleavers were just plain invisible.

Anyone else have this problem? Regardless, pretty horrific bug to occur. Especially from a support Mundo. Thanks in advance for reading, riot, cheers
