Basically this. I just can't go near it. I tried game cache verify - and it all right. Then I think that maybe it's happen because I used to many mod and disable all of them - and still got CTD. "Maybe my save file already corrupted?" - and so I started a game without any mods and with completely new character. Using COC command transport this new character to Bunker Hill and tried to go to Constitution - and still get CTD.
