Ornn ult bug, OX on steroids

This bug pissed me off soooo much. I was on my euw account playing Ornn support, even thou the champ is predictable i enjoy playin him. I never missed the ult.

In this game every time i casted the ult, even tested it on mid alone the elemental ox would just fly by past me starting from where i was standing. The ground thingy would flash red at the same time and my ult would be over. I downloaded the game after and replayed it, it looked normal so i couldnt post an attachment here The yasuo from my team wanted to see me cast it and he said he also couldnt see it.

Im speculating that it had something to do with my ult and another ornn ult (enemy) crossing above each other. The following picture shows where i saw the ox start and fly by next to me, elemental ox on steroids lul https://image.prntscr.com/image/fUhYCLOlT1C89CibVBZIlA.png
