This is a repeatable bug.
1) Search for any torrent that has a folder
-- For this example I searched ExtraTorrent for "Firefly" and selected this torrent: Firefly S01 Complete 480p BluRay x264-EncodeKing
2) On the "Add Torrent" screen click the [Select Files] button
3) At this point you might receive an indicator that there is insufficient disk space on your device. What to do? Do I add the torrent so I don't have to search for it again (and remove all the files) or do I clean up the space on my device and search for the torrent again?
3) Click the [None] button
-- this will unselect all the files
4) Click [OK]
5) Click [Download]
6) Return to the list of torrents on this device.
7) Select the newly added Torrent (which should now say it is 100% complete)
8) Click the Files tab
9) Check any file in the list to download it.
10) When it's done downloading look for the file on the device -- it's nowhere to be found.
Thanks
