The Wild at Heart

While the unlocked description specifically states "Stay up through the night until daybreak, outside of The Grove", mine popped while I was inside of The Grove the entire time from dusk 'til dawn (since I didn't know that it needed to be outside of it).

So once you head back to The Grove when the sun is going down, don't go to sleep! Just run around or idle until the music starts to change; it will be morning shortly after that and the achievement should pop around the same time.
