Just a heads up,
be carfefull about exploring your world unless your OK about starting new worlds to get new content.

The game engine generates the terrain out to a radius of ~500 meters from the player as you explore. Any area that is considered "explored" by the game will not get new content as the game is updated.

If you want to keep your world and your OK with using mods you can reset most of your map and get new content.

I've been playing the world I made almost 2 years ago and using the mod everytime an update comes out with some new content. it lets you protect areas of the map from being reset so you don't loose anything you've put loads of effort into.

PS: Ashlands is a great place to farm Surtling cores and charcoal. just wandering around near the water you will get more cores and charcoal than you will ever need. Up to you if you want to mine the flaming meteors in the area though, the devs will likely do something to render any stockpiles of Flametal worthless when/if then ever give the Ashlands real content.
