———————————————————————————
Going from Indelukket 25, 4040 in Denmark to Bad Kösen in Germany fails to calculate correct time for the ferry from Gedser to Rostock. It first adds 1h 59m and 48 km and then adds another 51m and 49 km for that part of the trip.
I would have liked to add a screen shot, but that was not possible through this.
