Every block a player breaks, drops a randomized item/block from all items that exists in the game. Blocks or items that should not be dropped are listed in a config file.
Also the Chest content can be randomized.
If the server crashed or restarted, the Block to Drop mapping is saved and will be restored.
If you want a new World or a new Randomizer you can simply create a one!
Do /randomizer to open den randomizer settings Inventory.
