hi everybody.I am in a very desolate situation. For no known reason all airports on my FSX scenery are not flat anymore and now have mesh breakthrough with trees and houses on them!I have installed FSGenesis mesh 3 years ago and never had any problems. No other mesh. I deactivated all my addon sceneries - still uneven airports.It is as if something is calculating lower airport elevations around the world or the flattening of airports doesn't work anymore.Does anyone have an idea what has happened and how I can find the problem?Reinstalling hundreds of sceneries and programs would be a disaster for me.I would be very thankful for help!Robert Picture of FSX default <Vancouver Int.> Canada showing mesh breakthrough. (Autogen slider = 0)The same situation worldwide.

I found the culprit!It was in the Terrain.cfg with a corrupt entry line (missing a separating Return) - causing a FlattenMode=flat not to work correctly.That saved me weeks of new installation time ;-))
