Cheers for the feedback! Will definitely add a north sea route. It didn't make it into the first build because the current navigation system only cares about finding the shortest route. So with an open north sea route, all of the Suez Canal traffic immediately reroutes up through the arctic... Should be pretty straightforward to fix though :)

Thanks for letting me know!! Will have a look into it :)

Oh, interesting! I thought I'd put in a check to stop that, but obviously it's not working... Thanks for letting me know :)
