Today, Yaga released a map software update (v 1.62).
When activating the coordinate grid (press "G") you can now also see the "map regions" as used in mission descriptions. There are 9 regions:
northwest, north, northeast, center west, center, center east, southwest, south, southeast
Map regions are shown by dashed black lines and slightly colored area overlays.
He also added a new experimental function: we can now display special deed info when the mouse pointer hovers over a deed symbol. (This can be useful to inform about special resources, like mailboxes, Epic portals, market stalls etc.)
Please contact me (Olufus ingame) if you would like to use this special feature for your deed.
