Features
- Added ground cover to the district map: rock, ice, desert, steppe, grass, woodland and lush.
- Added a button to recentre the map on your own territory.
Changes
- The ground palette now fades back under the Arable, Forest and Height map modes.
Bugfixes
- Fixed that thinly-traded goods swung in price every cycle, so buildings bought them in and out on alternate cycles.
- Fixed that housing showed FILLING / DECAYING for movements far too small to matter.
- Fixed that the map mode selector disappeared before the world map view began.
- Fixed that the country name and the map mode selector switched at different zoom levels.
