I pull my downloads folder. As long as their body shop content is base game only then there's no expansion data. Body shop content really doesn't effect .package files but it's best to have them in base game so that the sims aren't missing anything and so that they won't be linked to non existent files. Pescado would probably say that the files still aren't clean, but they are as clean as I can get them. I do always recommend that anyone downloading .package files always run them through body shop and re-clone.
