You will only have an issue for transferring a torrent (that was downloaded with a private key; public key torrents are different) at the SAME TIME as another location; this implies a shared private key. It not a problem at all if you download from one location, move it to another location and/or IP, and upload it from there. For that matter, you can even start a torrent at the library, take the partially-completed torrent home, and finish it there, as long as it isn't still being downloaded at the library.
You were most likely not seeing seed activity merely because nearly all of the torrents on BakaBT are heavily overseeded.
