Offer ID unusable after deletion of Offer
Offer Type is permanent once you start the process of offer creation. Offer ID is also unable to be reused even when the Offer is deleted.
That means that if you create an Offer with your desired Offer ID, and during the validation process it is determined that you had chosen the incorrect Offer Type, the Offer ID is no longer usable.
It seems overly punishing that an Offer ID on an offer that never passed validation or was published should be locked out forever.
If Offer ID and/or Offer Type were editable up until the Offer was published, or was not submitted until validation was passed, mistakes could be rectified without locking users out of expected IDs.
