Nami ult backwards/doesnt hit some targets.

Those bugs have been there forever and its affecting the games it happens in... Very annoying and game changing.

Sometimes (rarely), my ult goes backwards. This is the third time it happens and my ADC dies because of it.

Another bug is when the ult actually hits someone sometimes, it doesnt do anything, it goes through them like nothing happened.

I just cant take the game seriously after this happens and it affects the result of the game for my teammates in the games this happens in.
