This reminds me of a similar tracking behavior I saw last year. It was both frustrating and hilarious. Item shipped via FedEx from TX to CA. I think the ETA was 5 days.

   Day 1: Left TX
   Day 2: In transit in NM
   Day 3: Arrived in Tracy,CA
   Day 11: Left Tracy and arrived in destination city
   Day 14: Left destination city
   Day 15: In transit in southern OR
   Day 18: In transit in northern OR

It hasn't been seen since. When I contacted FedEx, their investigation showed that the truck it was on was currently sitting empty in WY. No explanation for why it sat so long in Tracy, why it left the destination, or where it ended up.

So the seller shipped a replacement.

   Day 1: Left TX
   Day 2: In transit in TX
   Day 6: Arrived in Tracy
   Day 7: Left Tracy
   Day 11: Left Tracy, again
   Day 12: Left Tracy, yet again
   Day 13: Arrived in destination city
   Day 15: Delivered
