New Option SPLINE_Waypoint didn't workout

Since version 1. 3.0 there is an option of “SPLINE_WAYPOINT”.

i’ve done a small flightplanwith mi Iris mounting PixHawk like this :

1.TakeOff
2.SPLINE_Waypoint
3.SPLINE_Waypoint
4.SPLINE_Waypoint
5.RTL

But after Takeoff (1) the run stopped there and didn’t go further, i had to stop the auto run manually by switching back to stabilize.

after replacing the SPLINE_Waypoints with Waypoint’s it worked fine, switching back to SPLINE_Waypoint given the same result as above,

spline WP are a feature of AC 3.2 which hasn’t been released yet.
