Alter Q leading inside terrain.

I played a gun run on skull town earlier today.

I placed a portal inside the corridor of North-Eastern building in center of the map which lead to inside of its hitbox, that would not be accesible otherwise. I like to push the limits with that ability and will update this post if I accidentally stumble upon other locations that are glitched in the same fashion.

I am under impression that this is not an indended gameplay feature.
