After Windows 10 1909 OS Build 18363.815 updated, you CANNOT savegames in any way shape or form. I had to roll back the update in order to get to save again. So if you want to be able to save to NOT update Windows as of apr 24, 2020. This bug will have to be fixed before I even come close to playing again.. already lost 3 to 4 hours of time. was fun! but all the work was for nothing.
