Retainers and Apperences

[MaethusXion]

As far as the house/private rooms, it's because no one aside from the homeowner/FC or roomowner can use the facilities within. My FC wanted to be creative and put the extra crafting station in a personal room... and only that person was able to use it. Same thing with retainer bell in a personal room, and vendors in the rooms. I'd guess it's all under that umbrella restriction.

I think that's kinda lame too. I personally don't see how using another FC's NPCs in their house is game breaking. I get why the garden, and furniture, and stuff is locked by why NPCs? It makes running Diadem HM a pain when I can't use the Party Leader's Repair and Junkmonger NPCs.
