Mundo Glitches when he wants to - The deadly invisible cleaver!

So recently I played ARAM with a friend and there is this enemy Mundo right? So you think cool cleavers to the face but then BAM! Out of no where I get hit by nothing. That's right, Mundo's cleavers on ARAM right now are invisible. Now I love dodging invisible miasma (thank you whoever fixed that) but invisible cleavers are extremely hard to dodge. I just wanted everyone to have a heads up to avoid those invisible cleavers, they hurt especially with the buff. I have no video but if someone can catch it that would be awesome.
