wipe it all if your going to wipe it. That way the goon squad that has c4 and explosives already will not raid within the first 6 hours of the wipe. Or hell making guns 1 hour in(yes I know they can just go to rad towns and get one but still) So please wipe it all if your going to wipe not just the map. Rustafied says there just going to wipe the map not the blue prints.
basically you got no blueprints, so you would like noone having blueprints. Gotcha.
Well then, it sounds like you need to start making rad town runs then in order to get yourself some BPs.
