So the new update announcement just dropped, and it adds another biome..

So will it be a type of thing where u wipe all chunks that have no player activity or whats the scoop...

Nope.

Are the map gonner be expandet insted?

Considering the new additions to the game, I'd be perfectly fine not adding them in. I'm probably alone in this, though lol

Im sure there is plenty of map not yet explored

Okay
