I have both ORBX scenery, and mega scenery earth 2.0.  When I use one, the other is disabled.  Recently, however, when I disable the ORBX scenery, and activate mega scenery Oregon and California for example, many airports have sunken runways. All elevations were fine with mega scenery California, but after installing ORBX Northern Cal, the sunken runways appear in mega scenery California even though the ORBX scenery is disabled.  Does anyone have any thoughts on why this might be occuring?  Thanks

There is a fix for this - I had the same issue when trying out P3D.  I can't remember it though :(

If I do, I'll post it!

Funny, I posted this same issue yesterday. I got one reply but it was not the issue. I hope there is a fix.

Even though you deactivated the Orbux scenery, there are still files in \Scenery\World\scenery to change elevations that might still be used. Those people need to quit mucking with airport elevations just because they can't fix the terrain any better way!

Well, I fiddled around a bit and was able to get rid of the sunken runways by this rather clumsy routine:  I did not disable the FTX scenery with FTX central, rather I disabled the FTX scenery areas manually within the fsx scenery folder.  However, the FTX "CFX" folder must remain activated for the appropriate flying area, then the mega scenery airport elevations seem to work ok.  Maybe a better way to do this out there.

I am a newbie with the Orbx software and I am experienceing the sunken runways also.  I have fiddled a bit with the scenery library and that make it worse, so I retreated a bit.  It's still not fixed, so am looking for possible solutions.
