Hi.
Recently, I had to abandon Research the Corruption quest because after collecting required items, the NPC (Gershala Nightwhisper) did not show the question mark on his head and not let me finish the quest. Now, I want to take the quest again but NPC won't give me the quest. I've abandoned some other quests and theirs NPC always give me the quests again but not this one. Could you help me?
Thank you in advance.
