Symptom: When I create a new route by using pins/breadcrumbs after 10 to 15 pins all of a sudden the route changes when I drop in a new pin..it changes to a different route, like having chosen the shortest route or so.
Explanation: This occurs when the routing system cannot find a route using all the waypoints (click points) that you have specified. If it cannot find a route, it falls back to choosing the shortest route from beginning to end. We are looking at this, although choosing the best behavior is not as obvious as it might seem since the underlying issue is that the routing system thinks part of it in unroutable.
Here's what we suggest:
- as you are clicking to add points, observe WHEN the route fails
- then click the "remove last point" button to remove the last point, and place it somewhere else, or move it to somewhere else. The positioning of this point next to a different road segment, for example, might fix this.
Also, check what routing mode you are in -- you might find the "gravel" option might work in this case, if the routing system thinks one of the roads is unsuitable in normal "road" mode (See FIGURE 1)
