Quest: Rescue the Farseer
Location: Nazjatar
Problem: Step 1 is to find the cave Farseerer Ori is located in. Step 2 is to kill Tidebinder Sarjezi and get the prison key. However, if people are killing Sarjezi in front of the cave, it is possible to get the key BEFORE the game acknowledges that you’ve located the cave. If you loot the key it will not work. If you kill Sarjezi again, she will not have the key because the game knows you already have it. You must abandon the quest and start all over. It’s an easy fix. The game knows you have the key which is why it doesn’t drop a second time. Just have the game check for the key once you enter the cave.
