I often have these buildings placed and sometimes one of the legs dont touch the ground, if the ground is very uneven that is, such as a hill side.
Or when the ground relatively flat with some bumps, the feet of the metal buildings sometimes sink into the ground and not aligning/rotating itself to the contours (shape) of the terrain.
Now my request is to allow these legs to extend appropriately and the feet to sit on the terrain appropriately.
While this is not a major feature, it would be a nice touch to the mission.
See the quick mock up of what I mean in the image I uploaded, i made it in paint so not the best demonstrations but I think it shows what I am explaining.
