As an old Humble Bundle key, this will most likely be "Townsmen - A Kingdom Rebuilt", not "Townsmen" (unless the key is from an earlier bundle and a lot older than the Humble keys for the Kingdom Rebuilt version). Maybe check again to be sure, then if necessary delete this giveaway and create a new one for the correct game. Otherwise this can lead to some problems later, mostly winners that can't redeem and Steam Gifts being unable to detect activation since it is technically a different title.

Thank you for this giveaway!
