Hi!
I love Transmission! I have my torrents downloads on an external disk, like many of you.
I don't really know in which version, but the behavior of Transmission when you open it without the disk connected changed recently. Instead of pausing all the torrent, a special error tells you to reconnect your drive and that's great!
The problem is if I connect my drive and restart the torrents, it just redownload it. If I use "Move data to.", the same thing happen. The only solution I've found is to check for local data for every torrent (which is very long).
Did I miss a way to recover the torrent without checking local data? Or that's more a bug?
