I have recently purchased La Palma X airport from aerosoft. All my GSX is working, but all GSX items are buried half in the Apron and Taxiways, as if running around about 2-3 feet under surface/ground level.
There was a similar problem some time ago with Maderia X, when all GSX items were running around actually under the Aprons etc. At that time Ricardo-R produced a BGL file that corrected the issue.
Not sure if he is able to help on this one, but if not are FSDT able to help?
Many thanks
