QuickChat

"one-way" - Unidirectional isolation. Messages FROM the isolated world stay INSIDE it (other worlds don't see them). Messages FROM normal worlds CAN be seen by players in isolated worlds. Private messages (/msg) are NOT blocked in this mode. Ideal for arenas where you want players to stay informed but keep their own chat private. isolation-mode: "one-way"

We recommend deleting and regenerating world-isolation.yml
