Why can't I find caves?
I'm pretty sure I covered all of my map with my friend but I still can't manage to find caves.
How is that ?
Solution 1:
After wondering for about a day, we finally found out that there's an option that is not enabled by default in the world creation.
This option is disabled by default because it requires the host to have 2 worlds (top ground and caves) running at once, which drains a lot of resources.
