I was hoping I wouldn't have problems like this, since I don't even have the DLCs. But now when I try to leave Megaton, the screen goes black when I get outside. No controls work, but I can still hear the music and everything. If I restart and fast travel out, then come back, it seems to work. But if this is some sort of corruption, I don't want to just keep going and leave it in there. I went back and deleted all the last saves since the last time I quit, hoping that would fix it. But it still does it. So I don't know what changed to make it start doing this. Any suggestions? I'm afraid it will start doing it when entering or leaving other places.
