NEW ECONOMY SYSTEM: There is now a brand new economy system with all new prices. The currency = Skulls. Why skulls? because emeralds are duplicated easily.
NEW SPAWN: The spawn/safe zone has been revamped!
NEW RULES: You used to be not allowed to kill villagers, however, this rule is no longer in effect since we have a better functioning shop system. Now it is also impossible to change shop prices thanks to the book and quill update!
