Rek'Sai Tunnel Twisted Treeline

Ok, I just finished playing a game on TT. My team was myself playing Kennen, TH3 RAVEN on Orianna and ChiefMagoo playing Zed. Enemy team was AbyssalEdge playing Zyra, OxidizedGreen the Rek'Sai and OxidizedRed playing Singed. Just wanted to throw this all out there off the top in case it helps in some way.

Anyway, we were East side of the map and enemy team spawned West side of the map. At whatever point in the game, Rek'Sai had made a tunnel from the brush to the West of the buff platform going towards the jungle camp that's slightly South-East of said brush. Anyway, we'd been doing a really awesome job in keeping these tunnels in check however this particular tunnel that I've just explained could not be broken.

And apparently this Rek'Sai fellow was catching onto this because he abused the shit outta the fact that we couldn't kill this damn thing! Unreal. This needs to be looked into. Wish I had more infos that might help.

Thanks Rito!
