Hi
I am a Discovery mod fan, but Crossfire just landed onto my computer 
I was exploiting SP and that nomad base took me some time(hehe, 10 minutes)
For all those who wants onto nomad base in Styx:
- first you need an editor, which can edit freelancer savegame files
->I am using FL Tools, where you can find a programm, which can open fl savegames
->supposedly Windows File Viewer Lite works too, but no on my comp 
There are two way of presenting location:
-> on base
-> in space
The easiest way to enter that station is to get into that system, exit the game, open last autosave with your editor, search for location, delete lines with "pos" and "rotate" and write "base = (location from that system)_01_base". Then you save that file, enter the game load that autosave and you are in that Styx base.
You could also downwrite that location and next time, when you start SP, you can write that location into the file, change your starting credits and you can start the game with ragnarok or with whatever you want.
Have fun
