[GAMEPLAY] Mundo's invisible cleaver's still not fixed

Occasionally, the enemy team can't see Mundo's cleavers. I'm not sure how to reproduce this, but it's happened to me on a few occasions (I think it might be random). After a quick google search, this has been an issue for a couple months. I did not record this video, but this is exactly what happened to me. I have a match in my recent match history against a Mundo where everyone on my team confirmed that nobody could see them, so it wasn't just me.

Could Riot at least address this glitch and talk about whether it's getting fixed? Or even if anyone from Riot has noticed it at all?
