Hi. I joined Stormcloaks and beat evrery quest from them. When i look at my achivments list i saw that i dont have one. One that you get after beating/capturing Fort Sungard. Is there and way i can trigger something (i mean go through some doors or smth like this) or is there any command that can help me in this situation.
