I'm afraid I don't quite understand your answer.
To be clear, if you:
* make a fitting model
* run one or more fits
* re-run feff
* save and close artemis
the next time you open that project file, it is *guaranteed* to be
broken.
As I said, this is a shockingly obvious avenue for failure. Until I
harden the program against this, the work-around is /never/ to re-run
feff after running a fit. In fact, you should /never/ re-run feff
after you have started dragging and dropping paths onto the data page.
