I think this is the right category; i flag this situation; when in outdorr I set a path the ford result impassable.
See example (https://graphhopper.com/maps/?point=43.864454%2C11.770778&point=43.862737%2C11.772602&locale=it-IT&vehicle=hike&weighting=fastest&elevation=true&use_miles=false&layer=TF%20Outdoors)
also in this case the ford hinder the path
sorry, i had signaled the problem in another category
sorry for my english
Yes, this is a known limitation and we will allow fords once we can include warnings in the instructions: https://github.com/graphhopper/graphhopper/issues/236
