I downloaded the new version and the problem is still there. How do I delete all the save files? I don't mind starting fresh. Edit: I figured out how to delete saves. Should I delete the "persistent" and "auto-X-LT.save"s?
If you really want a clean slate 1. install the game into a new folder 2. delete the entire folder called SpaceJourneyX-123456 or similar that is in Windows <User>/appdata/roaming/etc... (save your multiverse file before you do, maybe...)
