Zoe's E passing through a big Nautilus

Playing as Nautilus, I got a complain from enemy Zoe saying that her E doesn't hit me and went literally through. I saw the replay and indeed, the orb of Zoe's E didn't hit me. I was channeling Nautilus A (animation just started) and Zoe spell did hit my Yasuo mate right behind me... Also, I think my warmog was just beginning to passive heal if it can help... you can find the replay of the bug on my profile (EUW server). Thanks
