[GAMEPLAY] Urgot ultimate gets cancelled while/after channel (Patch 7.2)

So basicly, I was playing urgot yesterday, and everything was great my ults worked as it should for few times, but then I saw that something went wrong: I started channel it, so me and enemy couldn't do anything, but after fully channel nothing happens, I was standing where I started cast it and enemy didn't change his possition too. Firstly i though that enemy just died, or someone stunned me, but no. From that moment every time i tried to ult someone it just didn't work like before, no matter if it was in 5v5 fight, or 1v1, ult just didn't worked properly. I didn't cancel it manual (if it's possible)

First video where ult didn't work Next failed ult

Today i tried play him again and the same problem occurs (i used only 4 ults in whole game, 1st worked, but 3 next didn't work)

First video where ult didn't work Next failed ult

It's hard for me to describe why it happens (I have got full game replays if you need I can send them). I found that some other people had this problem since patch 6.24, I didn't play urgot a lot of time, so I can't confirm it.

I hope that it will be fixed soon, today I played urgot in community event, and my team lost a game because of useless ult (and because enemy team was better)
