Crash on loading a route (Mapfactor Navigator)

Hi MapFactor Forum,

I try to load a saved route by clicking on "My places" -> "My routes" -> "Click on route name" -> "Load". The route has a lot of waypoints (approximately 500). The App crashes constantly. If I reduce the amount of waypoints the app does not crash. The route was imported previously by "Route Importer" from a gpx file.

Tested on Nexus 5 with Android 6.
