Unfortunately, the urge to start over took hold and I again built up this mosaic by stages. My workflow gets me to the same stage as previously; but now, having cleaned up the unrelated cp's, I can still only get to a 9-image mosaic. Adding image 10 and 11 again results in a scrambled result in the Fast Pano preview. The translation parameters after optimization look ok, so perhaps there really is a bug? One workflow step I did change, based on further reading in the Hugin FAQ, was the mode of the horizontal line I've added to each image. That mode is now set to 'horizontal line' rather than 'Line #', as it seems better suited to the purpose at hand.
I've attached the PTO file in the hopes it can reveal the issue I'm having now. If the images would help I can upload them to the cloud and post a link. Thanks for any insights you can offer.
