This is a Stand-Alone Fix for my own Base Super Sea Platform Landing Base, for my Sea Bases Series, it fixes te problem for the Platform itself, now it is possible to land on it, but now it is impossible to fly below it, the reason for that is that the base is underground but still visible.
Warning, this will replace the old Base, but I dont think you should back up it because this one is much better!
Warning, unless you use the Super high-RES Level 9 Earth 3.0 texture by Jim Willians, the island where the base is on might not be visible, I highly recommend that you should download that add on first. The reason for that is that the island is very small and it might not show on any other texture pack available for Earth.
