All planets and locations from the previous version have changed. You cannot revisit a system from 0.97 in the latest, version, you can only export it in 0.97 and then put the exported file in catalogs/planets (and add it in universe.cfg) Quote Windswept
I tried exporting the system from 9.7 and dumping that generated file into the 9.7.1 scripts folder,
You need to put the file into the catalogs/planets/ folder and you also need to add it in your config/universe.cfg file, and not in the scripts folder.
Also remember to add a star which your planet system can orbit around.
