Using the existing 'World Map Location' dev tool, the world map can now
be given an overlay to show all the region boundaries and region ids.
This should make it easier to find out the region id of a specific
location.
One caveat is that this does not work with 'stitched' locations,
such as Motherlode Mine.
The map region change is triggered when a game starts loading new regions, but that doesn't necessarily mean the player is in the correct region. Additionally the currently loaded regions reveal very little information about where a player is actually located. Instead of relying on this event, the plugin now listens to game state changes, which are triggered for player region changes. When that happens, the plugin checks player region against the actual kingdom regions (2 in total).
