I have a problem with the imperial quest line. I was completing the mission where you have to release the imperial prisoners from a fort by sneaking inside releasing them and attack from the inside. now me being me I cleared the fort before i released them and after I had released them I was told to report to hadvar so I go to him and talk to him BUT it dose not allow me to "speak" with him so I waited a few times, rather than just reload a save. now the save I needed to go back to has been overwritten and I cannot continue the quest line if anyone has any ideas please help
