I've checked all those place. I can find NO editable files. I've included an image that shows the files I see from ../library/application support/hero lab/Data/pathfinder/
None of those files are editable in the Hero Lab Editor. My suspicion is that the individual datasets (like Bestiary 1) are somehow in Bestiary1.pkg. The only problem is I don't get a 'Show Package Contents" when I right-click so I can't see what's in them.
Very frustrated.
