As of this update, the game will track if you accused Leona while defending Kaisar in Chapter 4, so there will be a reference to it in Chapter 6, which is still in development. If you don't replay, it will be treated like you backed Kaisar but did not accuse Leona (it doesn't make a huge difference.)
Also, the wording in some lines near the end of Chapter 5 has changed, but the meaning hasn't.
