....and the reason that they are unapproachable (the docks), and are like hitting a wall 30 feet in the air is because, as Doug alludes to, that the docks were made with a hardened surface and then resized somewhere along the way, which causes this issue. If that particular object is placed as is and not resized, then the problem wouldn't happen, but maybe the original size is too big to look right and looked better at a smaller size.
