The developers of Legends of Aria don’t want you opening a world map any more. You shouldn’t have a world map in a sandbox, according to their design philosophy. The latest patch removes that function and will allow you to now purchase physical maps for the five world areas from vendors. You can also place notes about locations on those physical maps, although presumably you don’t need to buy a pad of sticky notes to do so. (Sticky notes had not been invented.)
The patch also allows for secure trading between players as well as transferring house ownership, and there are also new combat balance changes for players; Strength now has a greater influence on weapon damage and Affinity plays a larger role in evocation damage. It’s a smaller patch, but these changes should have a pretty big effect upon the game as a whole, possibly by getting you lost much more often.
