I was playing on the first level of the Bodhi's Dungeon, just after leaving the Asylum. I explored the entire deungeon and read some guides on the Internet and, what is supose to happen is that I need to find the hand of one vampire (wich I got it) and three gems that act as keys (With I got 2). A golem give me one, and a goblins give me another.
What happen to me is that after completing the puzzle from the statues, In the chest appear an Ioun Stone and a Star Sapphire, that has a different description from the other two gems and are stackable(Clearly, it's not the third Gem Key).
Then I go to the portal, I use it, a werewolf appear: I kill him, and a gem dissappear. I use the portal another time, a Demon appear: I kill him, another gem dissappear. I use the portal by third time: Nothing happen and the Star Sapphire does'nt dissapear and I'm unable to use the portal anymore.
If I use CLUAConsole:CreateItem("MISC8Y") and make appear the Sapphire with the same description as the other gems, the portal do exactly the same thing that happen before at the third time I use it.
I don't know how to solve this, and for that, my save is broken. At least, I have some savegames just before enter the Asylum and the Bodhi's Dungeon.
A savegame file are attached, just before using the portal by the third time.
