I didn't know we could gain extra battle hearts before this update (what was the way to obtain those before ?), so i only had 3 until then.
Now i have 10, bought them with the NPCs, and i'm pretty sure i got all of them because i looked every locations during morning/afternoon/night time.
Yet the acheivement is wierd, i'm guessing it's a bug ? Or am i missing battle hearts ?
I'm also curious how those hearts were obtained before. I wondered if you obtained a heart if you lost the minigames a certain number of times, because after losing, it would show progress on what looks like a "heart event" with the main character. I initially thought that would be a kind of special game over scene, but when I filled up the progress for it, I didn't notice anything happening.
