Square Enix has delayed the release of Final Fantasy XV update 1.21 for unknown reasons, with the patch having failed to roll out yesterday as previously scheduled. Oddly enough, the update has also vanished from the game's official website, which isn't exactly encouraging news.

There's been no word from the publisher regarding the delay, and it's not yet known when it'll see the light of day. The update would have been quite substantial, as it featured the end of the Assassin's Festival, the addition of a new training partner, and a new standby option when at a camp. 

Other additions include fresh items for Alessio's trading camp, new drills for the tutorial, plus another round of obligatory bug fixes. The most recent Final Fantasy XV update included the ability to swap characters among other features. 

Square Enix announced earlier this month that it will release Final Fantasy XV: Royal Edition on March 6, which bundles the original game alongside all available DLC. The PC version of the JRPG will also launch on the same day.
