The Options > Downloads > Automatically Add Torrents From directories do not work.
As with previous versions of qBittorrent, I save torrent files to these directories. In previous versions these torrents would then appear on the torrent download list in a paused state. I would un-pause them, resume them, and they would download/torrent properly.
Now, however, these torrents do not appear on qBittorrent's torrent list.
This only happened once (as soon as) I ran version 3.4.0alpha.
