Long time? I did the same (changed the range) and lasted ten minutes... Anyway, about the stations, I think PR should include other canon ones like the stations I mentioned in the Space Stations topic, not upgrade the Golans: there are no other models for them and each Golan is distinctly different from the other...
I meant like ships are upgraded (Impstar I, II, etc.) That way they can remain on the same technology level as the other ships in the game.
