If you run in to any errors, follow these steps:

Items

Drop chances

The following instructions speak of the ChanceOfDrop variable in each chest category.
When a chest spawns, the plugin picks a chest according to the set drop chances.
Set the chance of this chest dropping with a value between 0 and 1. (For example 0.2 would equal a 20% drop chance)
The lowest chance a chest can have is 0.01 (1%).
The sum of all 5 chest drop chances should equal 1.

Other options

MaxZRange: The maximum Z distance from the 'center point' that the chests will drop.
MaxXRange: The maximum Z distance from the 'center point' that the chests will drop.
Set the time between drops in minutes. (Make sure to give players enough time to reach the chests)
CenterOfZone-X: The center of the zone in which the chests drop.
CenterOfZone-Z: The center of the zone in which the chests drop.
dropWorld: The world in which the drops should happen. The nether/end are not recommended worlds.

Only OPs may use these commands.
