Route calculation never comes to end

[hike39]

My version of OSMAnd pro: 3.5.5

Since I updated to the newest version of OSMAnd I have the problem that the calculation of several routes never comes to end.

After the message "fast calculation failed" with an index etc it continues with the slow calculation which goes on for "hours".

I've already updated the relevant map. But that did not have any positive effect.

And we expirience the same with the smartphone of my wife.

Best regards

Can you share starting point and destination?

And di you use specific settings? avoid motorways, avoid toll roads, etc.

Starting Point was the service station ARAL near Weyarn,Germany (47.86413 11.79666).

Destination: Ansbacherstraße 21, Rothenburg ob der Tauber, Germany (49.37593 10.18745)

I can confirm that problem.

I've tried "Magic Earth" which uses OSM maps, as well. It has no problems computing the route.

When going by car I do prefer Magic Earth since it uses very few bandwidth and the traffic information is in real time and extremely precise. It reroutes automatically if the planned route is blocked or has a very long delay.

Any route from Aral Weyarn to close of Rothenbur or even center of Rothenburg works fine, but not to Ansbacherstrasse 21.

Routing from Rothenburg center to Ansbacherstrasse 21 works as well.

When I block the Ansbacherstrasse from A7 exit to Rothenburg it works as well. Something is wrong in the map at that specific point.

Routing in openstreetmap.org using OSRM works as well.

I don't have time to check openstreetmap to see if it is really an OsmAnd bug, or a recent change in Openstreetmap and changed back.

Note that Magic Earth maps are 3 months older than the OsmAnd maps.

I've done some tests and found out, that the problem is the transit of the street segment ID 315255992 (Bild1.jpg) onto ID 315255987.(Bild2_jpg).

There the value of the key 'change:lines:backward' changes from 'no' to 'not_left|yes' and the value of 'cange:lines:forward' from 'not_left|yes' to 'no'. in addition the number of 'lanes:backward' from 1 to 2 and 'lanes:forward' from 2 to 1.

You can see that in the attached screenshots.
