It seems that the user modifiable config file, ./GameData/KramaxAutoPilot/Extras/FlightPlans.cfg, is only being loaded once - at time of initialization.
If you select "Refresh", or exit that scene and then go back,you are unable to ever see the data from the "FlightPlans.cfg" file.
This is shown in the ksp.log, and it looks like on refresh or subsequent reloads after initial that the path is 'off'.....
i have included the ksp.log, and both config files.
