hi alex
i just found out that the filenames in the products_attributes_download_groups_to_files only refer to products_attributes_download_groups_files.download_groups_file_id but not to the .download_group_id.
so this causes a problem for different descriptions with the same download_groups_file_id.
you would just have to add a field in the products_attributes_download_groups_to_files for the group...
maybe you could build that in your 1.1 release...
