I'm a Steam user and am currently having problems with my game. Whenever I enter the BoS bunker and get gassed my game crashes while loading the content. I walk into the bunker, and to the room where you get gassed, fall to the ground, get four notivication that my followers have returned to their towns and that I lost their perks and then the loading screen pops up. During the loading screen my whole game crashes back to Windows.
When I try to check the integrity of my game cache it says there's one file that is corrupt and it'll download that file (though it's probably a small file because it finishes instant). When I run the check again it says my files are ok. Then when I run the game again to see if it works it's still broken and the cycle of checking begins again (one file corrupt, next check all is fine). I've tried restarting Steam several times with and without the integrity check but this didn't help.
