Today, 12:09 AM - Quick Update :
There is slight issue with utorrent 2.2.1, and some of the recently auto-uploaded torrents. These torrents have been tested, and are working in other clients such as deluge, rtorrent, and so on. The issue only seems to happen when using utorrent 2.2.1 .
It will be corrected with the newer auto-uploads.
If you experience an invalid torrent issue when using 2.2.1 on some stuff, switch your client temporarily, or upgrade to a newer a version of utorrent, and everything will work fine.
