Every time I go near the CIT, I crash, straight to desktop, and fallout 4 closes, no pop ups, or anything else. This is also true for flying over it in a vertibird, making the "Shadow of Steel" mission impossible to complete, even with console commands. This is my second play through and I am using the steam version of the game, on ultra graphics, and I haven't spawned anything in. I have verified the files multiple times, and the only way I could think of fixing this is loading to a previous save, but my last save was only a little after Vault 111 (I don't svck at saving, saving svcks at me).

Is it the same as http://www.gamesas.com/topic/1546438-fallout-4-crash-in-specific-area/

If it is then the Beta patch should resolve this for you

Thanks, huge help.

No problem dude, best of luck
