Four packages arrived on the same truck, only one got destination scan

[Tou Piao]

Is it usual?

I am expecting four packages shipped by the same shipper.
The tracking says all four packages departed at the same time, and arrived at my UPS hub yesterday also at the same time. So I assume they arrived on the same truck.

However, only one of the four packages got a destination scan in the afternoon, the other three packages have been staying at "arrival scan" status.
Is it usual people scan packages arrived on a truck, and stop at the halfway?
Not sure if I should be worried about them gone missing.

The google lead you here, but unfortunately this is not a UPS help line. You can check with the UPS 800# or the UPS facebook page.

The shipment might be loaded in two different trailers, check to see if they are all scanned Monday morning for delivery.
