Ran a couple tests on that one,, 2 possibilities for earlier versions,, if Phi Phi islands depth was corrected in a later version then that's why it would do that in the default start point,, in the 2nd start point there are some AI sailing ships right in front of you so possible those were moved in the later versions. But with V1.3 doesn't do it,, of course if I try moving forward from the 2nd start point I'll get rammed by those sailing boats
That pic looks to be from the 2nd start point between the islands.
