Spline prefab problem - resets spline

[yezzer]

Hi!

I'm using Unity 5.2.2f1 (Android) with Curvy 2.0.2, and I'm having a problem with a spline prefab.
If I change the shape of the spline, then hit apply on the prefab, it resets back to a square

There's this error in the console:
NullReferenceException: Object reference not set to an instance of an object
FluffyUnderware.Curvy.CurvySplineSegment.get_localPosition () (at Assets/Packages/Curvy/Base/CurvySplineSegment.cs:704)
FluffyUnderware.Curvy.CurvySpline.IsPlanar (CurvyPlane plane) (at Assets/Packages/Curvy/Base/CurvySpline.cs:1988)
FluffyUnderware.CurvyEditor.CurvySplineEditor.OnEnable () (at Assets/Packages/Curvy/Base/Editor/CurvySplineEditor.cs:39)

Any ideas?

..actually that error may be unrelated.
If i drag the prefab into an empty scene, then just hit apply (without making any changes), it resets back to the square.

Do you have a CurvyShape (e.g. Rect) attached to the spline component? In that case it's working as intended, because CurvyShape applies the shape when updating. If you want to apply a shape only once, disable or remove the component afterwards - that's how the editor shape wizard does it when hitting "Close" instead of "Save".
