Skupos Updates & File Consistency

With the 12/13 Skupos refresh, the old and new files going by the same name do not seem to have the same content. For example, I have two versions of the file “Convenience_Retail_Transaction_Items-0-DATE_TIME-2019-07-01”: one version from a download on 10/27/2023, another version from a downloaded on 12/15/2023. The contents of these files do not match. The same is true for “Convenience_Retail_Shopper_ID-271”; I haven’t checked others.

Does this mean that with every Skupos update I need to re-download the entire data? Not just new files?

If so, could this be changed in the future? It would be more efficient to only need to pull files with new content from the API.
