During the quest "Sacrificial Bloodlines" when I choose to 'attack' during the conversation that starts the quest and then kill everyone combat does not end.  Someone named Lliras walks in 'nods', I get "nameerror" in the combat log and combat continues despite the fact that he's not hostile.  I've reloaded and this happens no matter what responses I choose between starting the conversation and picking 'attack'. 
   
   
   
 I was unable to compress either my savegame or the output log to less than 507 kB
