Giskard, I noticed you said that you couldn't get Solars to appear on the minimap. I made a system using your tutorial and the Ringworld system, and added/altered a lot of my own stuff to it, and I found that all the stuff shows up on the minimap - planets, asteroids, stars, all there! I don't think I did anything different to the tutorials, if you want I can post the system.ini file so you can take a look for yourself and see if you can spot what it is. I do know that it's the 'property_flag' (I think, don't have Freelancer on this comp to check) line that governs what the image on the navmap is, but that only applies to asteroids or nebulae.
On another note, have you worked out any more on getting the Systemshortestpath.ini to work?
