I've noticed something today. Some of the characters now properly show their previously missing bloomed artwork if you select them as your assistant leader, even though you can't select it in their character screen. Examples include Anemone, Epidendrum and Ivy. I thought I was imagining it when it showed up at random, but it's there.

EDIT: Monotropastrum, gentian (though she inexplicably gains pink hair), pine tree and chickweed too. Basically all bugged ones I have.

EDIT2: I suppose that means Peach and Plumeria too? Haven't bloomed them yet.
