I finished killing the newborn dragon at the burial site with Delphine. As I traveled back to Riverwood to meet her at the Inn, everything was okay. I talked to her and she told me to meet Melbourne in Solitude. That's when everything screwed up. A thug appeared outside of the inn and started attacking me. Then EVERYONE did! I can't go anywhere without being killed instantly.. it's pissing me off. Help? :/
