so im playing dead money, i bring dog/god to the place.. and then i go to bring dean to peusto de sal.. and when i go to enter the door.. my game crashes, i've tried reloading the game re save.. its not working every time i go to it

Same here. It seems steam (or bethesda) is slow to respond to this. In some cases, I dropped all weapons and was allowed to enter crash free. Other times that didn't work.
