Accalia it's hardly outdated. i still use this as a film set myself.
I cannot download it? I must be able to Place stuff here and there... This one sadly doesn't make sense to me xc
From memory this map is very very simple.
You only need to place files called "Machungwaville.FHM" and "Machungwaville.FHO" into the folder inside the feralheart main folder called "Exports".
Then it should work for you.
