Ok, the cargo round just ended with the itani convoy reaching divinia, however it seems to have counted the itani cargo as arriving in the new round, not the old one. Also a UIT had cargo from the round and delivered it after the end.

Perhaps a 5 minute pause between the transports arriving and the end of the round, and all cargo from prior rounds could then expire when a new round begins.

Not that it matters, just not sure if this is functioning the way it was intended to.
