In the case of an interrupted upload, Duplicati will remove files that did not make it to the destination and then cleanup the database.
In the special case where multiple files were sharing exact metadata, the cleanup step could sometimes remove metadata that was needed. This would be detected and the repair rolled back, but the backup would fail to run.
With the fix the criteria for removing metadata has been narrowed to the correct subset.
