Some of us are blessed with Fourier eyes, others with QFS memory. :)

Honestly, I remembered because the event gave me an aversion to ever using QFS in a large Artemis project, and when I saw a similar issue on the list I recalled why I avoid QFS.

I think in the changelog you mentioned whatever you did to fix my problem had some effect on how the fit history was saved, breaking compatibility with earlier versions. It seems (although you likely know much better) that there's some quirk about how QFS path data is saved which can (perhaps still) generate errors that are different and not as well-handled as atoms-derived path data.

Wow! Jason, that either impressive or really creepy!

I concur that those seem really similar. And I don't see any evidence in my change logs that I ever actually addressed that complaint. Apparently patience is a virtue. :)
