Hi - don't know the policy for these but am providing landmarks for your reference. Haven't seen these residents in months - like 7 or 8... Have attempted to contact them but no replies, activity, or traffic...
All three are set to "No Entry" so the landmarks are next to the plots in question:
Dorn's House - Gearsawe's corner, Aglia (63, 78, 46)
Massiel Estates - Aglia Valley Store, Aglia (143, 66, 49)
Aglia - First Land - Aglia Valley Store, Aglia (143, 66, 49)
Thanks!
