Getting external rows to be more consistent with the internal API - the formulas should be processed using the outputProcessing as they were being processed, but was causing an overwrite. The problem was that the external system internally processed the formulas/relationships, then squashed the relationships. Once it got to the external API, it would go through normal output processing, which would run over the squashed rows, causing an inconsistent behaviour.
