Description
When trying to use one of the shortest path algorithms, e.g. point to point, the resulting path does not follow the network everywhere, but it takes shortcuts (please see attached screenshot).
Steps to reproduce:- Load the attached 'network' Line-Layer
- Create a path with the processing algorithm "shortest path (point to point)"
The other tools show the same problem (layer to point, point to layer)
