TBF this second update was primarily because, either by accident or on purpose, they had Akashi improvements survive plane conversion quests, meaning you could get, say, M53 Iwamoto +10 by upgrading before doing the conversion. Obviously this was unfair for those who'd already done it, so they had to release a method for them to upgrade their planes as well.
