I am having an issue with editing spline waypoints in the latest beta version of mission planner (1.3.66 build 1.3.7070.16921).
When I insert a new spline waypoint it inserts at coordinate 0,0 and cant edit my selecting the waypoint and dragging it to a new location it snaps back to the original location
The same thing happens if I load a previous mission with spline waypoints
