Hi Marco, Hi Michael,

Marco, thank you very much for catching this and posting to the list Marco!

Michael, I would go for option 2

I have also sent an email to the mapper who made the mistake. Mistakes
happen, it is just the nature of things.

If someone wants to fix them up via option 2 above, please let us
know. It will take me at least an hour before I can dig in and fix it
myself, but I will let the list know when I do if no one has started
before then.

Thank you again!

Regards,
Blake
