I’m not sure that the problem is two points being coincident with each other. Rather it sounds like the typical issue of having two features with the **same** feature ID. When both are added to a topology then it becomes ambiguous as to which feature should be used (so neither are used). It usually happens when a feature is copied (rather than cloned) such as when a GPML is copy’n’pasted (and so the feature IDs are also copy’n’pasted).

This [post](https://discourse.gplates.org/t/which-features-are-chosen-by-topologies/190/2) has more information.

I’m not exactly sure how you copied - you do mention a copy but it also sounds like there’s only one feature added to the topology. In any case, feel free to send me some example data that reproduces the problem.
