I may be mistaken, and if so I apologize. I believe there are a couple of quest that are not working correctly. When I try to speak to the necromancer, I get the response "I have nothing else for you." I can not accept the quest and I have 10 bones ready to give that he will not take. I read through the forum here and see this has occurred before. I have had similar situations with the Wounded Man quest. I have given him the bandage material but his brother will not respond to me when I return to him. I think he may be mad at me =(. I thought I was having trouble with the leather quest, but when I just tried saying "yes" he took my leather. I may have had that quest active without knowing it. I have tried this approach on the other quest but they only respond with "Sorry, I don't understand." I am use to this response as I am a teacher, but they still made me sad. I am able to do the fish quest and leather quest with no problems. I am only aware of these four quest so I am not sure if any other quest exists or are broken. Again, if I am just being a noob feel free to let me know. Thanks!
Edit:
I forgot to mention that I asked in /h if others were having this problem and some players confirmed they had issues with the quests I mentioned above.
