So, now i dont want to load any old saves at all. I went back a bit and found a save with much more of what was missing still in it. think it was about 10 days back in game time from where i was (174 vs 165), Happy days I thought and played an house or so, rebuilding most of what was missing. Left the game and just went to go back in after a few hours. Back to everything being missing. Everything I've built is gone and when I exit it creates a save showing 0 days and about 4 hours. It took me 3 goes to get it to load when I came back. It kept loading for about 20 seconds then crashing to the xbox dashboard.
So are all save files basically useless now?
