i'm trapped in Solitude during the quest Liberate Solitude, in particular after we've confronted general tullius and whats her name.. the script runs fine but when the general and the legate attack.. they are invincible.. i can beat them but the general just gioes down to one knee and you can't talk to him or anything.. it doesn't trigger a surrender or anything.. and the legate gets beat down to nothing.. goes down on one knee.. then gets back up again a few seconds later at full health.. if i sheath my wepaons they stop attacking but again nothing happens.. the door back outside is locked, presumably until the general surrenders.. is there a fix??
