• The dwarven, human and Nurn villages lay the mod's stone path block where a vanilla village lays a path. Dwarven and human streets, the stubs that close a road off and the fountain plaza still behave the way vanilla's do - a tenth of a street still grows over, and a street crossing water is still bridged - and the driveway and the porch at each house's door are the block outright. Nurn's roads, its road stubs and the plaza around its well walk on the block too, where the desert village they are built from walked on smooth sandstone; its walls, well and lamps stay dark stone.

• A Nurn lake no longer writes outside the chunks it is allowed to write, which filled the log with Detected setBlock in a far chunk errors as the player moved and left the edge of the lake and its grass shore cut off. The whole lake, water and shore, now stays inside the feature's write window.

World generation

• Mordor and the Ash Mountains no longer hold water. The dimension's aquifer fills those biomes under the sea level and in pockets high above it, which no biome setting can change, so chunks now turn that water into lava as they load. Terrain generated before this change is converted too.
• Nurn is the watered half of that country: dark stone ground broken up by cobbled patches, tan water, a full 1.0 of rainfall, and no lava of its own anywhere in the biome. Grass grows only near water - on the low shores and islands a few blocks above the water table, and on the meadow a lake lays around its own water - so the biome reads as dry ground with green at its edges.
• Nurn's lakes are dug by a feature of their own, at most two chunks across, and asked for once every 18 chunks so the lowland carries the occasional lake rather than a chain of them. Each one lays the grass meadow around its water, up to sixteen blocks out, and the whole lake stays inside the chunks a feature is allowed to write to, so nothing is left with a missing edge.
• Nurn's villages are the vanilla desert village rebuilt in dark stone. Every sandstone and terracotta shape is swapped for the dark stone block of the same kind, the farm rims that were sandstone stairs become deadwood log fences, the crops stay the desert crops, and the roads get their own terminator pool, because the desert pieces that close a road off are raw smooth sandstone and do not pass through the street templates. A Nurn village only starts on dry ground.
