Rek'sai E bug

I'm sure people are aware of this one but I'd thought I'd post anyway.

I was playing reksai in poro mode. I had used my underground E ablity but died mid flight. There was one half of a tunnel there for the rest of the game. I could ult to it but it couldnt be destroyed. At one point I could have won the game because of it but didn't think that would be fair.

Please fix!
