I've been informed that this issue is fixed and we are hoping to push it to the game as soon as possible!I created some video to show exactly what is the issue.
Short summary - we need to change the tileset from WorldMap to None and use our own vista. (which is painted outside of scene editor)
This first video shows that the painted terrain is working in the Scene Editor but when the map is loaded in the game it is not there.
Just a side note - the quality of the vista is also worse in game as in Scene Editor.

Another video with the original tileset - WorldMap. This is not customizable at all.
