Play() does not cause SplineController to produce expected behaviour

[ConCat]

Out of interest, is there a reason that on Initialisation, it would override any values supplied before it?

To be honest, I don't know. The asset was created by another developer before I acquired it late 2017, so I am not aware of the motivations behind many of the old design choices. Even when I find a behavior not justified or improvable, I often avoid changing it to not break users' code that relies on that behavior. I do sometimes choose to introduce breaking changes, but I need to feel that the benefits are worth it.
I do have a ticket regarding reworking the initialization process of some scripts (from memory: CurvySplineSegment, CurvySpline, CurvyController, CurvyGenerator, CGModule) to harmonize them and reduce/remove the frames needed for initialization, but it's not a high priority task.

Thanks very much for that insight, and I really appreciate your honesty on it too.

I appreciate the work maintaining this project might be significant, if you ever need a hand creating or updating some documentation or looking into anything minor, feel free to reach out and I'd be happy to help if I've got some capacity.

All the best, and thanks again!
