You loaded an old save it looks like
in 0.0.9e, Stations were spawned by the engine every time you saved and reloaded/shut down the game/etc
In 0.1.0o, stations are only spawned on new game, and from there, Save to the file, and reload from the file
This includes position data, as it is now possible to move stations around.
You will need to restart in 0.1.0+
