There seems to be a mix with prisons inside Mana-Tombs with their position, what they should spawn and a missing one.

To explain it short, there are supposed to be 2 statis-prisons in Mana-Tombs. 1 should be near the beginning of the instance which is in heroic mode. This prison serves a purpose for a Consortium quest. You get the key when you accept the quest, and you finish the quest by using it on the prison to release the person in it.
The second prison is in the last room where Shaffar is. This prison is used to unlock an optional boss on heroic that is named "Yor". You get the 1 use key(https://www.burning-crusade.com/database/?item=32079) for unlocking this prison by doing some work for consortium and dailies. Once you are exalted, you can get a permanent key(https://www.burning-crusade.com/database/?item=32092) for unlocking this prison.

That is how it should work, but right now these dont seem to work or is not making sense.
----------------------------------------------------------------------------------------------------------------
The issues:
1. The object "Mana-Tombs Stasis Chamber"(https://www.burning-crusade.com/database/?object=185519) is in it's wrong position. It seems you guys are using the wrong prison object at the wrong location. On your server right now, can see tooltip at the bottom right(Ignore th e addons!) http://i.imgur.com/gijkx2l.jpg
2. The object I mentioned above summons Yor right now. Since it is a different prison, it requires the quest key, which has absolutely nothing to do with Yor, and would mean that people can keep on summoning Yor after getting this quest. This is pretty much using a bugged state at getting a certain optional boss to spawn everytime for your mana-tombs without actually getting done to Consortium rep/quest requirments.
3. Shaffar's Stasis Chamber (https://www.burning-crusade.com/database/?object=185522) seems to be missing from this instance. This one should be in Shaffars room instead of the other prison, and this one should summon Yor, not the other prison.

The fixes that need to be applied:

1. Make sure that Mana-Tombs Stasis Chamber summons Ambassador Pax'ivi. Right now, this object summons Yor. (http://wow.gamepedia.com/Quest:Stasis_Chambers_of_the_Mana-Tombs, please read the notes section)
2. Place the Mana-Tombs Stasis Chamber at it's correct position.

3. Shaffar's Stasis Chamber is missing right now. It should be at the spot in Shaffars room where the wrong prison is at.

4. Shaffar's Stasis Chamber should have the Yor summoning script once people unlock this prison.
5. Make it so that the quest http://wow.gamepedia.com/Quest:Stasis_Chambers_of_the_Mana-Tombs gives quest credit with the small RP text once people unlock Mana-Tombs Stasis Chamber.
6. These should only be able to done in Heroic mode. I guess either don't make them spawn in normal, or make them uninteractable in normal Mana-Tombs. (http://i.imgur.com/5KqLDa1.png)
