This fixed my ground stations:
there is a quick hack on a per save basis you can do but the save has to be created first. Go into your save game folder and you'll see RemoteTech_Settings.cfg, open that, delete the ground stations section there and replace it with the one in that github link. That's where remote tech goes to pull its info when you start the game anyways. So if the mod manager callbacks won't do it for you, just do it manually after you start a new save if it keeps happening in the future.
