The reply has answered all your questions. Your application will be reviewed by the admission committee according to the mail you presented aforehead. However, given that your were applying for Divinity School of the most renowned university on this planet, I think this recommendation letter event would affect your application badly. It depends on the admission officer's understanding of such events. If I have to guess, the best senario is they consider your application as equal as if there were no such an event, which would be so difficult to happen. I would rather call this a cultural differnece rather than a cheat, which certainly is not your fault but just unlucky to be the black swan. Anyway, good luck.
