Re: Routes not displayed from Layers files
I see the same problem (on OSX) if I put the gpx file straight in the layers directory.
If I load (Import GPX) the gpx file via the routemanager and then select the routes in this file and export (Export selected) this info to the layers directory and delete the routes (and waypoints belonging to these routes) and restart OpenCPN the layer contains now the routes and waypoints.
Also the gpx file is now smaller than the original.
So looks like OpenCPN does not like the layout of the original gpx file as a layer.
I didn't see any corruptions during this procedure
