Note: Having one ribbon for both the challenge and completed achievement allows the challenges to also be categorized (which I think they should be) under the Tale of Two category. Pedalpusher (talk) 14:45, 13 October 2015 (EDT)
Another Option
I can probably make one ribbon without needing the duplicate for the completer's ribbon (IE eliminate the need for 'User1 earned' and 'User2 earned' ribbons) but the wording will be changed and both expeditions will be listed in the ribbon contents. Something like:
User1 and User2 earned A Tale of Two Hashes Achievement
by visiting {commonPlace} on {link to challenge report | date1} and {link to completion report | date2} respectively.
Doing this would be confusing though if there are multiple users for one expedition(which we already have).
