5th attempt failed w/o generating a zip and without completing the log page (where the log should appear as it had after the 4 previous attempts, only “Loading…” now appears)
The overall operation appears to be devolving, i.e., doing less and less each run. Is this a clue?
Am I misunderstanding, and the resulting zip files are parts of a whole?
