Bug Report : Clipping upwards through terrain

youtube.com/watch?v=EVZGhuljpN8&feature=youtu.be

I found this bug by accident while mantling in a cave, then I kept climbing in the same region until I found the spot again. I believe what's happening is that the game is only checking for empty space to mantle into on the block directly in front of you. If you mantle on the edge between 2 blocks, with 1 of them being available to climb and the other being blocked by something solid. Then the game mantles you into the solid block. I'm guessing they have a failsafe that pushes you upwards if you end up inside the map as well, resulting in the player being pushed to the surface.
