I know we're all sick of hearing it, but I think the developers of all those other space games really need to start cribbing notes from No Man's Sky more often. More than once I've seen silly bugs along these lines in E:D and/or Star Citizen and I realize that NMS already foresaw and preemptively solved that problem years ago. Generated structures in No Man's Sky will always have a patch of flat terrain created for their footprint, regardless of all other environmental factors. This can get quite silly at times including perfectly cylindrical patches of dirt rising from the ocean floor or city block sized golf holes driven vertically into the slopes of mountains. But by gum and come hell or high water, at least all the buildings touch the ground.
Did you get your SRV out here and drive around under the buildings to see what happens?
