So this is my second play through and I am avoiding Concord at all cost to avoid Preston (he's soooooo annoying). So, I've been playing for a while now and I decided I would liberate the Castle myself (not very hard). I killed the queen and cleaned up all living Mirelurks, activated the work bench, turned on the power, activated the Radio Beacon, turned on the Water Purifier in the back, ect, ect. I have about 6-7 settlers and everything seemed fine. So, I left and came back a few day latter thinking the settlers would clean up the place (remove MireLurk eggs, clear away all the debris and just clean up in general) but, that’s not happening. The place still look like [censored].
How do I clean up the Castle?
