The book/line nWoD: Blood and Smoke a styx chronicle is set to recieve a new name and cover (and no other major changed), and be rerelease as Vampire the Requiem 2nd edition
The options now are to:
copy the tag wiki across and delete the old tag, or let the tag delete itself when X months go buy without questions.
or to create a synonym (but fix the tag to be vampire-the-requiem-2e)
Possibly creating a synonym is unnecessary, and the wiki should just be moved. I think in this case it is more likely to be necessary since the book has actually been released under 2 titles.
