"Invalid state" is a system message in UniUni's tracking, not a physical stop on the route. It usually means the scan or update the parcel received did not match the step the system expected, so the tracking could not label it properly. The parcel is most likely still moving through UniUni's network, between a sorting facility and the delivery stage.
This message by itself is not a sign of loss or damage. It is a tracking glitch more than a delivery event, and the parcel can keep moving while the history looks odd. If the line stays as the latest update for longer than the previous steps took, treat it as a possible delay.
Normally the next scan corrects the record. That is typically an arrival scan at a facility, or a move to out for delivery. The history may then look tidy again, or the odd line may simply stay in the list as a leftover.
