If there is no connection between your footprint posts, this can be for two reasons:
- The route line option is turned OFF for the according trip. Check this, by opening the trip settings, then go to "Advanced settings" and look for the option "Route line". Make sure it is turned to ON.
- If there is a route line shown, but it does not connect to all of your footprint posts, please make sure that the option "Aside the route" is turned to OFF for the footprints without connection to the route line. Check this by editing the footprints.
