The crashes aren't random.Building something, leaving the area and then returning to the built stuff is currently crashing the game Exactly this, unfortunately happened to me too. When i reload i'm in my house, where i just finished to build a fence(not completely). I have Zeds banging on my walls so i have to go outside and trying with a shotgun to lure them away. On the way back as soon as i get close the game crashes. I reloaded 3 times but unfortunately on the 3rd Zeds got me b4 i could run off. It was only 10 days but i was doing good. I was on a new game on the steam beta. No mods of course for me. P.S. Oh, and just for the stats, without manually backing up(the game did it itself) my 2 previous saves from .16 work. I haven't played them, just loaded up to see if they could, so i don't know if the ctd would happen there too. I have the exact same problem
