My understanding is that the corrected HTA version came from factory sets and the error HTAs came from packs. It's been years since I did the research though and I can't find any of the information that I had used to come to that conclusion. Hopefully someone else out there has something more conclusive than my faulty memory. Once I concluded that the base version didn't have a corrected version, I moved on from this one.
