The country (NOR) for edge is not correct for destination here: https://graphhopper.com/maps/?point=68.408295%2C18.128023&point=68.408277%2C18.128039&profile=hike

Seems to be right on top of our simplified border.

Loaded the borders file into https://geojson.io and the problem is indeed caused by inaccurate simplification:

@otbutz thanks for checking this!

If this is a problem of an incorrect border we should improve the original data at https://josm.openstreetmap.de/export/HEAD/josm/trunk/resources/data/boundaries.osm
(Similar to how others changed it here or here. See also their github mirror here.)
