There are real problems with the Torrent files for collections. They are automatically created when a collection is first created and uploaded, and so they only include the files of the initial upload. For very large collections (100+ GB) it is common for a creator to add/upload files into a collection in batches, but the torrent file is never regenerated, so download with the torrent results in just a small subset of the entire collection.
The solution is to use one of the several IA downloader script on GitHub, which download content via the collection's file list. I don't like directly downloading since I know that is most cost to IA, but torrents really are an option for some collections.
Turns out, there are a lot of 500BG-2TB collections for ROMs/ISOs for video game consoles through the 7th and 8th generation, available on the IA...
Is this something the Internet Archive could fix? I would have expected the torrent to get replaced when an upload is changed, maybe with some kind of 24 hour debounce.
It sounds like they put this mechanism into place that stops regenerating large torrents incrementally when it caused massive slowdowns for them, and haven't finished building something to automatically fix it, but will go fix individual ones on demand for now.
