New Brevoort Formspring

Hi, Tom, a while ago you claimed there was a miniseries that you had to write the final issue of (uncredited) because of problems with the writer. Would I be right (with this vague clue) that the issue involved trying to resolve/retcon an element concerning the "arch-enemy" and their back-story which readers thought ruined the title character. (and these developments were later ignored a few years later).
