In the Core rulebook for WFRP 2nd Edition there is a note in the Navigator Career (page 78) that says "since there are no compasses in the world, all ships employ a skilled navigator".

Is this an error in the book or has there been some clarification of this somewhere else? There seems to be no information regarding this in any of the related books but compasses are mentioned in passing in other context (e.g. Inn names). Has this odd line been corrected by an erreta - or has any other published material expanded on this to suggst why this might be the case?
