text: Great report! I wish there were more notes like this! 
  
  You could also try some other pedestrian router. E.g. https://graphhopper.com/maps/
  
  Since you are the one who has had the problem to begin with it is easiest for you to try to recreate the exact same problem with some other tool.
  OsmAnd mobile app is another option (now also for iOS).
  
  If another router doesn't have the (same) problem then it's about the Mapometer and not the date (.. likely).
