Re: HOW TO CREATE APARTMENT?
@kwohld I only know what the mod documentation says: that normally, a door can only be designated as an NPC door if it's inside a room, or inside an enclosed fence (amounts to the same thing), but the mod allows doors not enclosed to also be NPC doors. I mentioned it because it looked from your screenshot like you might need that feature.
Can you use the apartment callbox to summon Olive Kipling after adding her? Does it help to "save as"/quit/reload? I haven't used apartments enough to know if there might be a delay in the ability to summon the sim using the door or if the callbox is more reliable. But I do know from reading mod-related forum discussions that this approach should work.
