OK, here is the bug. We went to the lighthouse and found the ghoul standing in front of the door and his skeletal buddies lurking nearby. I put a Flare into one of the oil barrels and created a huge area of fire that included the ground under the ghoul. He stood there in front of the door the entire time and burned to death while doing things like either re-animating some of his fallen buddies so they could fight us again or simply standing there doing nothing. He never moved and he never attacked us. We did not have to fire a shot at him to put him down.
Some of the undead lupine horrors were also caught in the fire but they moved out of it and came after us.
