Small changes concerning balance, gameplay, or graphics.
RSO may be causing a resource duplication after you save, close and reopen a saved file. It will duplicate the starting resources in the area and place them randomly in the starting area.
I upgraded RSO for an in-progress game and noticed new starting resource locations spawned, so the save-close-load isn't needed for the corruption at least for the upgrade case.
