Error : verify_nav: Invalid or no current Nav cmd

Guys,

On a couple of my flights I had this weird error verify_nav: Invalid or no current Nav cmd

The plane after launch, when put in Auto mode did not accept and started flying circles and totally ignored the waypoints. There were around 130 waypoints on the flight plan.

I suspect its due to some limit on the max waypoints this APM can take. Can we have a confirmation on this ? What kind of limit is this ? Is this limited to Pixhawk also ? 

Thanks ! This was wierd and is important for people to know the limitations.

Thanks
