Path 750228170 has been removed, while there was a green hiking trail on polish side. Now green trail ends in the field, while it's supposed to end on Przełęcz Lubawska (https://www.openstreetmap.org/relation/8297093). Have you seen that the trail has been removed? If the path is hard to pass maybe it's better to add trail_visibility=bad instead of removing the path. Recorded tracks suggest that people do follow the green trail: https://www.strava.com/heatmap#17.00/15.98177/50.68797/hot/all.
