Does an update change my existing worlds?

No. A world keeps the terrain it was created with through every update of the mod. New terrain in a new version
applies to new worlds only.

Do I need Alien Biomes?

No. Terra Nauvis runs on the base game. With Alien Biomes the ground follows real regions across a wider palette,
and Destroyed Europe, Blue corrupted UK and the Moscow zone need it.

Does it work with Space Age?

Yes. Terra Nauvis changes Nauvis only. The other planets generate as they do without it.

Does it work with RSO?

No. RSO replaces the map's ore with its own, and the game warns when it is active.

How do I pick the map, the scale and the city?

The scale and the spawn city are startup settings (Main menu > Settings > Mod settings > Startup). The map is a
preset at the top of the new-game screen: Europe, Old World or Atlantic.

How do I report a bug?

Open a bug report on GitHub.
The form asks for the mod version, the map, the scale, the spawn city and the map seed, which is what it takes to
find the same place again.

Where does the map come from?

The reference maps come from EarthMaps by HySpeed (GPLv3). Forest and marsh
outlines come from RESOLVE Ecoregions 2017 (CC BY 4.0), and canal routes use data from OpenStreetMap contributors.
