Okay so the problem is I have found all the obsidian chest and every one of them has let me interact but one and that is the obsidian chest in Mooshu Cave of Solitude..I have done this over and over and it is still not letting me get to it..even after defeating the boss..anyone else having this problem?
btw..I have reported this bug? hope to get this solved soon ;)
[size=15]I've also had problems and submitted several bug reports for a broken quest on the MooShu Obsidian chest quest.
Where I once was allowed into the building. I no longer have access. I have teleported into the building and the chest will not interact with me. I have completed all quests in mooshu and should be able to enter the building.
