It could be duplicate feature IDs somewhere (see [this post](https://discourse.gplates.org/t/trouble-creating-boundary-topologies/269/3))?

Perhaps some features were copied rather than [cloned](https://www.gplates.org/docs/pygplates/generated/pygplates.feature#pygplates.Feature.clone) when you created some of these features in pyGPlates. Copied features have the same feature ID whereas cloned features do not.
