I went to the usual place to get the obsidian chest in Ancient Burial Grounds (Crazed Forest Spirit aka Oakheart). I saw no chest in the room at all, so I decided maybe I needed to fight the boss to make it appear. After the battle there was still no chest. :-( Does anyone know if the chest is in a different place now? I cannot see it on my map like I can in the other areas, and I know I did not already collect it.
That chest is Kinda...... Well this is maybe a bug. Maybe you should send a ticket. And anyway, that not Oakhearth. Oakhearth is in another place in village of sorrow.
According to threads on other sites, this happens once in a while. For whatever reason, the chest becomes invisible. You need to walk around that room until you see a message popup to open the chest. I suggest checking the area behind the Sprite and the edges of the room first.
