If you haven't talked to Zynn Iwuhos before ever (easy way to do this is create new player and have them try to talk to him), the first conversation is totally bugged. After he introduces himself and says some words in blue, there's a question mark and ear icon next to him, which usually indicates a question. However, nothing at all can be said to him to get a response, not even "bye", and none of the words he says in blue, or any of the other common words such as "help", "offer", "quest", "job", "yes", or "no". You have to walk away from him a certain distance. Then if you walk back to him you can talk to him and his conversation functions properly. It just doesn't function right the FIRST time you talk to him. Zynn Iwuhos is the old guy in the back of the Semos library, by the way.
