But I am beginning to wonder about conflicts, since we have had several that are really inexplicable.

I certainly didn't delete this financial costs piece by Jérôme, for example. I would not delete a piece as substantial without referring to the author. And when you pointed out that it was missing, I would have remembered and said I took it out for one reason or another. I wonder if he and I were editing close in time to one another and one version scrambled the other.

And Jérôme didn't see the version that resulted from your copy-editing, then mine...
