So far as the supervisor I talked to (from the RI hub) said, she's been inside the hub the whole time, but we are also keeping the breeder up to speed.
By the time I realized the snake was being sent via UPS, it was too late to change it. I will be making sure I insist on FedEx in the future. Guess I was too naive to think people were still shipping UPS with its track record of losing packages (not only snakes but all packages). I just hope this girl doesn't suffer or die because of some dumb human's (be it mine or the breeder's) mistake.
