One thing though.
The map is infinite, and i think the spawn location thing works by saving coordinates.
And on infinite maps..
You know, there's no way, it's infinite.
i'd think that it would create the world around where you spawn, and the more you explore, it just adds onto the direction you are going like the infinite mining mod on BL....
also, has anyone found sand?
or bushes/shrubs that actually grow?
