As a guy who has spent over 30 years in international transportation, there is one "bug" that bugs me... :)
The container cranes at most of the ports in P3D are installed backwards. The crane arm is supposed to extend out over the water. In P3D, the crane (the tall arm part) is shown in a position that would extend it over land, not over the water. These need to be turned 180 degrees to put them right.
