Rek'Sai Tunnel/Ward

It's not much of a bug but more of a problem. If Rek'Sai has an active tunnel, and a friendly places a ward on top of the tunnel, that side of the tunnel will be in accessable to her, because the ward hitbox overpowers the tunnel hitbox. So I don't know a solution to a problem like that but let it be known. If there is a ward directly in the middle of Rek'Sai's tunnel, she can't use that side of it.
