I have also had this problem with Orbix GLOBAL....Its an excellent add on & a lot of work has gone into it making Flight Simming better than ever.
I notice that I have water problems around YSSY airport. Such as Houses in the water & TREES on the tarmac ! ^_^
I believe they are working on a repair patch & new add-ons .
Does anybody have the same problem >?....Any advice would be gratefully received
Happy Flying !
