After googling this problem, and checking the last few pages here I decided I should post my problem. My game crashes after a certain point. It happened the first time when I completed the main quest, but did not do the Broken Steel quests, but continues exploring. I saved in Megaton and the next day when I load it its all fine. I can save I can do whatever I want. But after traveling to any location, I cant save without a crash and after a few minutes of walking or entering a building the game crashes. So what I did the first time was load a older save game, before the last quest and continue exploring. That was fine until now. I reached lvl 18 and saved in Megaton and the crashes are back. I tried disabling addons, all different solutions floating on the internet but none works. Of course reloading an older one would probably solve it but I want to find a normal solution. Perhaps its tied to saving in Megaton ? Thanks in advance for any help.
