Test:
Disabled LSGG in the add-ons
Copy LSSG Scenery in the F:\Prepare3D V3\Addon Scenery
Declaration the scenery in scenery.cfg
THE PROBLEM IS GONE with FTX LC Europe / FTX Vector enable or disabled, Why !
That would only indicate OrbX tested its product only with the default scenery. You should have made the test in the opposite way: disabling OrbX and keep FSDT LSGG Geneva enabled. It would ALSO worked just as fine.
So, it's likely both that OrbX haven't tested their product with LSGG AND we haven't tested LSGG with OrbX.
But with a significant difference: we couldn't "test" LSGG with OrbX, since LSGG was made *years* before that so, we could only design it and test it with what was available at that time.
Instead, OrbX COULD have tested their product with LSGG and, since they were later on the market, I think the onus is on them to provide a patch to fix any compatibility issues they cause to products which were already on the market for quite some time.
