So basically, I want to be able to recruit Preston again, but he'll only keep harping on about taking back castle. I don't want to do that yet - I'm doing a fairly slow, steady playthrough and running that far South and dealing with a Mirelurk Queen is definitely not on my to-do list. Is there a mod to make him shut-up about it for now so I can recruit him again and do the quest later? For now I just want to get back to saving and building settlements. Thanks very much for any help!
Edit: It looks like We Are the Minutemen used to do that, but not anymore.
