### My Question

Does anyone know why the orientated bounding box from a point cloud would spit out duplicate points (i.e. not an actual prism)? Didn't make a bug because I haven't written code to reproduce yet. I was using Python 3.12. volume() returned 0 for the results. Also tried all the permutations of doing it (_minimal, not minimal, robust, and not robust)
