We post options to our paid Patrons each month to vote on which Rewind titles our members will get keys for and then we add community copies to those as well. This just happens to be one that is offered in this month's poll. It ends next week.
You can join our Patreon as a free member to keep up to date on what we add community copies to (all our new releases start with a large amount of community copies too), or I can reply to your comment again if this title is voted as a rewind title and we add them.
