Not sure if I should post this to Bug Reports or not. I restarted my game and on this run I raided Jamaica Plains, only one problem, Conqueror counted the ghouls too and one of them was a Withered Ghoul, now I am level 21, and it was a 'skull' level ghoul that kept getting back up after being beaten down. I had to spam attack and execute to time it to execute the damn thing *just* as it went down since it kept regaining it's health almost instantly. When I finally did the quest "Attack Jamaica Plains!" finally completed. Next time I know to go to Jamaica Plains and kill all the ghouls first *then* raid it.
