Again that's a different situation, it would have been booked in as accompanied baggage and from there it was an airline mistake that it did not accompany you.

It's also quite likely that it was already loaded in to a flight container & the container itself missed the flight, as the contents had already been approved it would simply remain sealed & go on the next available flight.
