It isn't counting as completed, no matter what route I take. I set up all defenses while befriending Father Bernard and Jeremy, don't give Bill any pain killers or alcohol, shoot Bernard/Jeremy, and kill Bill with the axe. I end up surviving and the "cutscene" plays, but the achievement won't trigger. Am I missing something, or is my game bugged? Restarted the game at least 5 times and restarted the player twice.
