That seems likely a question for the
Modder's thread and while i rarely even use the patch. It does have an step by step with even images
I'm mostly interested in changing how Flora, Natalie and Nicole address you by and even in pictures how you do see that the relationship is Mother, Big Sister and Little Sister and not as Housekeeper, Guardian or whatever the F is atm.
It's been a couple of months since played this from scratch so im going for sure start from 0 and stand corrected about the ipatch changing these things accordingly if needed to be used at.
