New content such as tar pits, mountain caves and Mistlands in the future will not appear in areas that have been already generated. Areas are generated 300-500 meters from a player's location. "Exploremap" and "resetmap" has no effect."

Well I guess it was hiding...in plain sight

Thanks

Also, anything that is a "trader's distance" out in the fog counts as explored. It renders about 500m past the fog. If you see the edge of a mountain on your map, consider the whole mountain spoiled.

I take it you've had the 'pleasure' of experiencing this first hand or is the definition of "explored" hiding in some dev post that I've not seen? Inquiring minds want to know (so they decide to restart/start a new seed).

Any parts of the map that are already uncovered (discovered) will not get the new content and the new content will only appear on areas that are far away from uncovered areas of the map.

This means that if a console command (or mod) was used to reveal the whole map, that map wont receive any of the new content unless the map is once again "undiscovered" (covered up again) and refreshed.

not sure but do the new stuff spawn on old saves?? otherwise you can search forever but dont find anything if you run on an old save

The new mountain caves will spawn on unexplored mountain biomes, even on old saves. Keyword being "unexplored".

If you want to find where the caves would be without searching, consider checking out Valheim World Generator[valheim-map.world]. You can punch in your world's seed and see where everything is that way. Hope this helps you experience the new caves!
