Fiora ult graphical bug

I don't know how to recreate this glitch but I can tell you the situation. I was taric top lane and I was fighting a fiora. I have chogath come chase me with fiora and then I get knocked up by cho and ulted by fiora. And her ult is vertical to the ground and you can only see the pink lines going above taric and nothing else. She was using project:fiora if that matters
