I have modified my home airport to match recent real world upgrades made, (YBUD regional Australia, no one else will use it, update it or look at it ever probably). The new runway length is 2000m and now after extending it in WED, successfully exporting it to X-plane 11 means the runway dips following the contour of the "land" making it weird to land/take off, where as in the real world its flat. Can this be fixed? and how please?
