@carlwhat, this version still removes/recreates those orders_products and orders_products_attributes records. There are notifiers now issued by EO when it's preparing to remove and then re-instate those records, though, so an admin-level observer can keep those additional fields intact.

That said, I expect to have that processing changed in the next major release.

If you find any issues, please report them here since I think that this support thread has a wider audience.
