Simple... everyone trying to identify the cargo. Flipped PS rides this bloody transit system all day long and does not rest or slow down (except when plaque builds up) and why don't many BPs declare this cargo as where all trouble begins? Maybe because Peregrine holds the patents and BPs will not make all the profit ...well, except the ones that license out these rights to exploit Peregrines cargo and soon Peregrine becomes profitable
