I'm not sure if I'm doing something wrong, but I got the Sword Of Misery, and the curse never actually happens on any of the enemy equipment. I'd get if it wasn't stacking, but it's not appearing in the first place.
There is one part that seems to be an event that happens before it's supposed to when you're gathering the purple flower as Maoti. If you try to climb the upper hill, there'll be a conversation with a woman you haven't met about seeing a man in black?
Same problem as the above comment. Fixed 2 days ago, but Kong doesn't let me update the game. I hope they resolve their cache problems soon. EDIT: This is fixed now and the conversation only appears once it's relevant.
That was a bug, we just hotfixed it. Try reloading.
