I speak to Legate Lanius, and I receive my orders. I proceed to the gate to start the battle, and it won't open. I don't have the option to open the door. I am stuck in this camp. Is there a way around this? I have had this problem before, and I had to delete the update, which makes all of my DLC perks, weapons, and equipment disappear.

For the past year, every time I fight under Caesar's banner, I have to do it without the updates or 4 out of the 5 DLC's. It's a shame, because I would like to play those DLC's with my current reputation. Is there a way around this problem?
