I just want to know Riot is working on the invisible abilities

I know it takes a while to fix. I just want to know that Riot is working on it as a top priority. Because it really-really sucks when you get hit with invisible abilities. In my experience, it's never a one off invisible ability in a game. It happens over and over and over on the same ability for the entire game.

Finally there's a video of invisible abilities besides the Nid spears. There's multiple threads on reddit and here about abilities going invisible.
