Nostalrius Begins - Quality wow vanilla realm (1.12)

So yesterday when I hit 50 I decided to do all the prequests for 50 priest class quest which in the end leads you ST. So in the end I got the quest the quest linked below and logged out.

http://db.vanillagaming.org/?quest=8257

Today when I logged back in I went to ST but when I got to the boss needed for the quest I saw I didn't have the quest anymore and I cannot pick it up again from the quest giver in Azshara http://db.vanillagaming.org/?npc=8405.

Can some admin help with this? I want to get back the quest or admin can send me the reward I would've taken from the quest which is http://db.vanillagaming.org/?item=19990 .

Greetings,

The sunken temple class quests have been removed and will be added in patch 1.7
