I don't know why but they seem corrupted, if compared with the original they have 2 or 3 bytes with same bits different, near the start fo the file.
edit: i tried to understand more so i examined the differences while comparing bit for bit, but more than missing bits seem that same bytes has their value increased or decreased so more bit changed in the same byte; for example i got a value 0x1b change to 0x2c
00011011 to
00101100
same bits are set to 1 and other to 0 so it seem that the entire byte was replaced with arbitrary value; sametime there are 3 bytes differents, sametime 2 and they're really close, there where other details to search for but i dind't.
Also the corrupted torrent (obviously) generate a completely different magnet url while magnet links posted by Girlcelly are correct, so the corruption happen while uploading of after the torrent upload.
