The quest "Taking Independence" is not going smoothly, as I cleared out all of the Mirelurk eggs and Mirelurks, even all the way down to the small dock and surrounding areas. Every time I try to speak to the guy standing in the rubble near the transmitter, only keeps saying there are more enemies to kill and they could be in the walls. I checked everything on top and in the open area of the armory and nothing is left to kill. I then try to go use the workstation and it tells me "cannot use while enemies in area". I am stumped and stuck.
