I can't seem to complete the quest for Neutt's Sand Castle destruction and therefore can't get the knowledge gained from the quest. When I approach Meutt's sand castle to interact with it I get the following text prompt; "This character does not exist, or is out of range". Stranger still, Meutt will give me the follow up quest to destroy Neutt's sand castle even though I have yet to destroy his. But then I will get the same text prompt for Neutt's castle. Neutt will then give me the same quest that starts the whole quest line creating a infinite loop.
