I've been looking into cloning worlds so that it will be possible to have multiple copies of Willow Creek and/or Oasis Springs. With a bit of extra skill, I hope to be able to mix-and-match cloned versions of neighbourhoods from each of the worlds but first thing's first: which files make up worlds in The Sims 4, and where are they located?
I know that there are .world files in <Install Directory>/Data/Shared/Worlds/Areas but those are only for the individual areas. I need to know where to find the files for the full worlds. Would worlds be as easy to clone as other parts of the game or would they require extra work? I know that in The Sims 3, they could be cloned merely by copying and pasting the .world files.
