I have refurbished Pleasance House in Chola Springs, New Austin into a little love nest for John Marston and Penelope Braithwaite. (Poor Abigail) I have also set her not to walk off so will stay around the house.
I have also set up a faithful border collie, but sometimes he doesn’t do what he is supposed to do!
Just take the file (once unzipped) and place it here (this is how it appears on my machine, yours may well differ)
C / Program Files / Epic Games / RedDeadRedemption2 / MapEditor / Maps
You should then be able to load the map once inside the game by launching the Map Editor (which you will need to install)
