please have a look at the attached GH definition with a patch component example. Depending on the number of spans, the patch component fails with a “…reference not set…” exception.
At 10 spans: Successfully patches all curves
At 20 spans: Around half the curves get patched successfully
At 40 spans: None of the curves gets patched
patch-bug.gh (40.9 KB)
Looks like a bug to me?
Thanks for looking into it.
