Bard Tunell Physics
Vayne managed to click an E on me either before I entered the tunnel or just when I did. I ended up outside of the tunnel and good 2-3 character distances away from it.
That is not a normal. I'm not sure if this is a bug because I know you can die in the tunnel (which is fine). However, I do not think you should be able to be targeted in the tunnel because I think that is what caused this oddity.
