In survival, it appears that the footmen want to all sleep at the same time. Have something akin tot he party screen where a footman can be designated for day or night patrols. Day patrols, they will act like the rest of the hearthlings. Night patrols, they sleep during the day, and follow their patrol routes at night. Also, have a sort of waypoint system of sorts, where a patrol route for specific footmen can be set?
