Hi all, it seems my clean-up enthusiasm caused some inconsistencies with datasets' deleted status. I encounter the following phenomenon: datasets appear totally fine in the data libraries, but once they are loaded into a history, they appear as deleted there. I dug through the database and found out that the following query returns all datasets in the libraries that were uploaded before my clean-up: SELECT * FROM library_dataset_dataset_association INNER JOIN library_dataset ON library_dataset_dataset_association.library_dataset_id = library_dataset.id WHERE library_dataset_dataset_association.deleted = TRUE AND library_dataset.deleted = FALSE; When I set both deleted to false, only datasets that were added after the clean-up appear. Do I break something, if I reset library_dataset_dataset_association.deleted to FALSE for the inconsistent datasets? I tried it for one dataset and that seems to have fixed the problem. Is this some bug in the clean-up scripts? I guess that actually they should have been removed completely. Best regards, Sarah
