"Unusable by NPC" not working
I am trying to lock NPCs out of various rooms in a community lot, and this function is not working. The doors ARE facing "out" of the rooms into the common areas. It happens with single doors, double doors, and archways. The rooms are completely closed-in, and there is either a roof or a floor above with floor tiles in all cases. There are no other doors or other means of access to the rooms. It doesnt matter if I have an active sim in the room or not. All of the visitors to the lot simply ignore the function and stroll in and out as they please.
I AM running mods, but they are Nraas mods, up to date, and have nothing to do with room access or anything else that would logically conflict with this functionality.
What am I missing?
