From what I can see you have the starsystemdef_UrCruinne.json and the career one in Streaming Assets meaning they will overwrite the whole starsystem files and cause your issue. You don't need to use the StreamingAssets folder. Move them to a StarSystem subfolder in your mod and add a line in your mod json manifest entry to include the starystem merges. { "Type": "StarSystemDef", "Path": "Starsystem" }
