Can I make a suggestion bud, in the future make multiple saves mate so if one becomes corrupt you can back track. I'm not criticizing you I'm just hoping to save you a lot of time and effort and if I can extend my advice a little further, don't rely on auto saves in anything if you can. Remember this games is still early access and although it receives all due care and attention required from the devs to keep it a relatively smooth experience sometimes problems will occur. The system I use in all things that allows for a little control over my data is a three save system and one back save. You save make three descending saves slots (save slots 1-3) and then after that you always overwrite the oldest save slot (so goes like this 1-> 2-> 3 ->1-> 2-> 3) and every so often (for me it is after about five hours game play) you make a save on slot ten so even if you mess up your three working saves you do not lose all of your progress entirely, a checkpoint if you want. Might seem tedious but for the most part, keeps you covered.
