Research direction
Start by loading StereoCenters_CD (Last4).zip and reproducing the CDX save failure in Indigo, checking the different SA and Remote error messages. Compare the result with ketcher (Stereocenters-not all).zip and the expected behavior described in the issue; done means the ChemDraw input can be saved to CDX while preserving the stereocenters.
