[h4ckc3llF]

Hello,
Im trying to do the "Master of Elixirs" quest in the "Black Morass"
I tryed to enter "Black Morass" and the game tell me that I must complete the quest "Return to Andormu" before.
I talked to "Andormu", for the quest "Old Hillsbrad".
I finished with "Erozion" in "Old Hillsbrad Foothills" and he give me the quest "Taretha's Diversion".
I finished the quest "Taretha's Diversion" with "Thrall".
Then "Thrall" gave me the quest "Escape from Durnholde" but I failed it the first time.
I canceled the quest and now "Thrall" let me to say to him to "Start walking" before accecpting the quest "Escape from Durnholde".
I followed "Thrall" outdoor killing all NPCs and then followed "Thrall" to "Tarren Mill"
I killed "Epoch Hunter" and waited for "Erozion" but he don't let me to complete the quest "Escape from Durnholde" and I am stuck here.
Can you help me please ?
