[Fiora] Blade Waltz damage/animation not completing but still invulnerable

So basically, the title. It didn't seem to need any special circumstances or anything Fiora R'd me as Teemo three times in a game and it would hit and damage twice but then put Fiora behind me while still untargetable for a short moment. Tried it again with Fiora vs. Rammus. Same results. Ultimate would begin, 2 hits, then the animation would cease, she was behind me and unable to be targetted. These were noticed on Howling Abyss. My friend posted a video of it for the sake of the PBE, also, he's salty because he loves Fiora. lol [https://www.youtube.com/watch?v=irJeZmAx48M](https://www.youtube.com/watch?v=irJeZmAx48M)
