Hello, so I apologize if this has been asked before but I am having issues at Madeira where parts of the terrain just kind of slowly rise into the air. For example there's a thin section of grass next to the taxiway that looks fine until part of it gently slopes up and curves up into the air. As well as few other areas that float into the sky. I've tried a few things like reinstalling the airport running ORBX elevation tool. Anyone know what might be causing this?
I will try and add some pics when I get home.
