I havent found any way to repair advanced metal extractors. Moreover i´d like to make a suggestion. I think there should be a option to show all units on the surface. especially on planets with vegetation its hard for me to see them. Or they should be more colorful (like the teamcolor). Then there could be an command or key to rotate the camera, not just move. I hope everyone understands my english. greetings
This is mostly because the advanced metal extracter exists of 2 parts, the small extractor with the advanced ontop, and you can both still select them with some pain
