In the attachment rebuild process I discovered that approx 30K uploaded images are missing from between early July and mid Sep 2020.
They are in AWS S3 storage and somehow missed the mega image migration of XF2 upgrade. So they are not lost but... it's going to be an effort to migrate and re-organise the folder structure -- and then rebuild thumbnails just for that (not insignificant) batch.
So.. if you find missing images in historical threads - please report here so that I can confirm it is indeed just the known gap detailed above that is missing -- and not some other random time period as well.
