I uploaded a save of Island Paradise with changes that I found mentioned by other simmers as troublesome. Because a save folder has a few different files in it, it requires a few files downloaded and placed into one save folder. Then, use that save as a template. In other words, use "save as" to save your play. Then this save will stay untouched for another save later.
