Shipment tracking disappeared

Good morning, I hope this is the right section.

I bought a parcel, which the seller correctly shipped, providing the tracking code. This appeared in the “purchases” category, as usually happens, until the parcel was marked as “forwarded to the Perugia branch”. At that point, the option to track the parcel disappeared, meaning that in the purchase history, on my order, neither the shipping code nor the button to view the shipping history appears anymore. What could have happened? Should I consider the parcel lost by now, or is it an internal eBay problem?

Thanks anyway.
