OnControlPointReached not triggering when metadata attached

[cyclo]

Hello there,

In my game i make use of OnControlPointReached.AddListenerOnce().
The problem i run into is, that every once in a while (maybe 1 out of 200 runs) the Listener will not fire for control points where there is a Metadata script attached to it.
It works fine most of the time, and i have no clue what could cause it not to fire in these rare occasions.
Any ideas? The code looks something like this:


       protected override void Start(){
           if(Application.isPlaying){
               OnControlPointReached.AddListenerOnce(OnCPReached);
           base.Start();
       }
   
       public void OnCPReached(CurvySplineMoveEventArgs e)
       {
           if(Application.isPlaying){
               Debug.Log(e.ControlPoint.ToString());
               var metadata = e.ControlPoint.GetMetadata<FinishMetadata>();              
               if(metadata!=null){
                   Debug.Log("has metadata attached");
               }
           }
       }

So on a good run the Console output will look something like:
Spline.CP0002
Spline.CP0003
Spline.CP0004
Spline.CP0005
has metadata attached
Spline.CP0006

on a bad run:
Spline.CP0002
Spline.CP0003
Spline.CP0004
Spline.CP0006

CP0005 is just missing and not "listening" at all ....

That's weird. And it happens only for CPs with meta data I guess, right? Can you tell me what Curvy version you use? And also can you send me a reproduction case?

Yes, only happens for CPs with meta data. Curvy version is 5.2.1 and Unity version is 2018.2.10f1
For the time being i made a workaround, i will send you a reproduction case once i got a bit of time on my hands.
The reproduction case would ideally be just a Bezier Spline containing some CPs with metadata attached and a SplineController with the OnCPReached listener.

I tried to reproduce but couldn't, even with thousounds trigerred events. I looked at the code, and I don't see anything obvious that would make the event logic depend on the existence or not of metadata. I attached the scene that I used to test it. Let me know if my test scene do reproduce the bug on your setup
