"A smaller section of wall that can be placed into corners to allow for perfectly-fitting walls." (OLD)
The Corner Wall is a wall that replaced the old corner walls. The problem was that the old corner walls took up unnecessary space, so the new corner wall was made, which doesn't take up more space than it needs.
The old corner walls took up an unnecessary 8x8 units, disallowing other items to be placed inside of it because of the hitbox.
