I found a 2nd site that further corrobrates the Miracle ticket schedule presented in my guide (originally culled from the JP wiki updates to the Miracle ticket section). It lists the Dec 2017 Miracle ticket as the 4th ticket released in the DMM version, following the Dec 2016, April 2017, and August 2017 releases. I see no evidence at all to support this claim of a February 2017 Miracle ticket.
