When is Ver. 0.60?
[Spoiler] 0.60.1 Contents
In the deepest level of Misty Abyss. At 0, 3 position, there a small chance you can get a scarf by investigate this "?" grid. (I try around 10++ times and just find one)
I suggest you to save at the nearest point of this grid (for me 0, 4 is fine) and interact to it, if you couldn't fide it, reload the save and try again. Since when you interact with it, it will disappear, and you need to re-enter the level to interact it again.
