On the Factorio container, I am trying to start the server with only Base game and no space age mods. When I edit mod-list.json to have the three new ones to false and only base true, as soon as the container starts, it immediately overwrites the file and loads a space age save. Am I doing something wrong?
I even tried making a non space age save from the game and importing the save file, it still starts with the space age mods enabled.
