I am currently on the part of the mission where I need to talk to the ranger about protecting the president. The ranger will talk to me fine and I can tell him I am ready. He then tells me he will brief me in the morning and the screen fades out. When it fades back in, the game freezes. I have tried every possible method of trouble shooting I can think of and still haven't been able to find the issue. I think I'll try killing the BoS and see if that will allow me to finish the quest, even though that is not how I would like to complete the story. I also have the pc version of this game and could easily port my save over. Does anybody know how I can fix this issue from the console? (setstage maybe?)
