Description

While hbck2 runs through fixes to meta, the Normalizer kicks in to "help". Mostly this is fine, however, things get confused when fixMeta is action on a region and then the normalizer decides to do something as well. Could be we advise operators disable normalizer while running hbck2, but would be better if the normalizer was less aggressive, so that there's fewer flags to fiddle.
