For some BioCASE-based datasets that lack source occurrenceIDs such as https://www.gbif.org/dataset/e88fdc62-ea3b-41a3-8967-b3780f602c0b, I've seen re-issuance of new gbifIDs upon recent re-harvest but apparently no significant/relevant new adjustments or enhancements were made to records in their source. For instance, this occurrence record is deprecated https://www.gbif.org/occurrence/1946076733 whereas it has been issued a new gbifID, https://www.gbif.org/occurrence/4981443192. In other instances, it looks like the interpretation of occurrenceID and occurrenceStatus has been mistakenly swapped, resulting in an issuance of new gbifIDs. See https://www.gbif.org/occurrence/144842729 and what appears to be its replacement https://www.gbif.org/occurrence/4979384474 by way of example.
