Today, while playing my level 6 Theurgist, I noticed that the quest helper believes at least some of Wizard City is Austrilund, Grizzleheim. This error is consistent in these locations:
The Commons is designated as Austrilund from any location in Wizard City. Diego to Ambrose quest says Ambrose's office is in Austrilund. The Commons Smith is located in Austrilund, Grizzleheim
