I'm currently doing the "Join the Stormcloaks" quest. I've already killed the ice wraith and am attempting to return to complete the quest. However, upon entering the palace and taking a few steps forward, I hear a soldier (it sounds like it's from a distance) say 'That's close enough!" The threats related to trespassing are repeated again and again, as long as I stand there. If I try to walk any closer, everyone in the palace attacks me. I don't have any bounty on me, I can actually talk to the guards right inside the door, and they're not hostile or anything. It's only when I try to walk forward that triggers this attack. I can't complete the quest! Please help!
