I'm a bit concerned about this 417-GiB torrent (last seen complete = 2023-11-09 UTC):

[Loyaldk] My Little Pony 4K Upscale
magnet:?xt=urn:btih:73605190116277ddda6bc24ee91c08a2af27a7e2&dn=%5BLoyaldk%5D%20My%20Little%20Pony%204K%20Upscale

I was unlucky >>10331 and 20 GB worth of files in that folder got corrupted.
>/z8/t/[Loyaldk] My Little Pony 4K Upscale/
was copied to
>/za/t/[Loyaldk] My Little Pony 4K Upscale/
with ~20GB missing. z8 is mounted as RO, za as RW. I couldn't get qBittorrent to change the location from z8 to the za. I tried doing that when pause, when unpaused, and after force recheck then quickly pause. Each time it tried to move the folder instead of just change its location. qBittorrent v4.6.0 couldn't move it due to being mounted as read-only, not that I wanted it to because each time I click "Set location..." not "Move...". Annoying, so I remove it from the transfer list then re-added it. Before doing that I copied these to files in "/home/ubuntu/.local/share/data/qBittorrent/BT_backup/": "73605190116277ddda6bc24ee91c08a2af27a7e2.fastresume" and "73605190116277ddda6bc24ee91c08a2af27a7e2.torrent". The .fastresume file has bencoded info such as:
