I accidentally did a batch change of version names intended for 6 photos, change 81K. Apple Z didn’t seem to work, so I clicked more than once; hence, nothing seemed to change back. I probably didn’t give it enough time.

If I create a new library with the 700 photos that i have not updated to my vault; then create a new vault with those 700 photos; then restore the original vault, would that work?  

Any suggestions? thanks ahead of time!  sharon ann
