Hello, The Wailing Caverns quest 'Deviate Hides' is bugged. My questlog says that the quest is completed, the npc that gives the quest has a yellow questionmark above his head. However, there are only 19 hides in my inventory (you need 20), so I can't press the 'continue' button to actually complete the quest. Since it is 'completed', there are no more hides that drop. Aborting and retaking the quest doesn't help. Any advice? Kind regards x
