Anybody else unable to clear this place? I've done it on previous playthroughs but this time its just not happening.

I turned off the turrets at a terminal in a trailer, killed all the raiders outside then went back to Sanctuary Hills to sell all the loot before I went back and killed all the ghouls throughout the mines. Well now everything is dead (I spent an hour crawling through it firing a pipe gun every 20 feet or so and the "hidden" display doesn't even move slightly so theres nothing down there that can hear the gun shots.

Now I'm reluctant to turn on Freedom radio in case I get a mission to clear Dunwich Borers because theres nothing down there and the interior is not respawning, the exterior quarry part does though.

Not good because doing minutemen quests is how I raise approval with my companions.

Dead raiders inside the mine have disappeared, dead ghouls are still there. All corpses looted.
