Not sure if there's another thread but, this was added to the preliminary patch notes.

Due to an operations error, some items to be implemented in future patches, such as Patch 2.45 and 2.5, were incorrectly included in the Patch 2.4 notes. Because of this, we have removed these items from the patch notes. We apologize to players who were eager to obtain and enjoy these new items.

One of the items removed from the list was Wind-up Nanamo, not sure what else was removed from the list.
