PCG error on unknown overlapping spline points.

[KingKerel]

I am trying to work with PCG for the first time.
But even when just starting out I encounter an error which I can not solve.

I get an error indicating that spline points are overlapping.
I can find only 4 spline points, and they do not overlap.

If I delete the spline from the actor, the error goes away.
Adding a spline again makes the error come back.
So it must be this spline that is causing the issue.

All I can think of is that it somehow remembered the past (deleted) splines, which did have overlap.
Renaming the spline does not make the error go away.

Does anyone here have a suggestion of what to try next?

I was trying out some things to fix it, and came up with more questions.
Specifically, how are splinepoints being checked for overlap?

Should I implement splines in a different way for PCG?

Do you have an example project that has this part fixed?

I have been trying more things out in order to fix the error.
And I found out the game compiles and runs even with the error.

Also I changed the “Interior Sample Spacing” and “Interior Border Sample Spacing” around somewhat.
And this had an effect on whether the error was there or not.

So I guess this whole time the error had nothing to do with “overlapping spline points”.
I think if the “Interior Sample Spacing” and “Interior Border Sample Spacing” align exactly (which happens at certain sizes) it gives an error.

Why is this an error?
And why does the error refer to the spline points overlapping?

Any links which might be helpful regarding this issue is welcome.

Were you able to locate a solution to this? It appears to still be happening.
