Maybe a bug in adm-zip https://github.com/cthackers/adm-zip https://npmjs.org/package/adm-zip? Using it to package the zip files, but no real need to use NodeJS for this purpose. Could possibly switch to command-line Info-ZIP. Or isolate this problem with adm-zip (if it is a problem with it and not my scripts, somehow).
