Hello! I recently downloaded your domed city addon and i love it, makes really good scenery for screenshots. My only question is that is there any way to not make the cities tumble around on the ground once time is resumed?
in SE 0.98 my cities are like ships, if you block the orientation to the horizon, this will help.
you can also go in debug mode and set "force orbit" for a major stability.
anyway, these are only tricks. there is no way to add fixed objects to the ground.
with the release of SE 0.99 things should change. but I don't know if it will be possible to add stations and cities only to the planets of the catalogs or even to the procedural ones (although I don't think, unfortunately).
