- Lots of itemstack cloning removed. Only clone if the item is actually moved - Return true when a plugin cancels inventory move item event instead of false, as false causes pulls to cycle through all items. However, pushes do not exhibit the same behavior, so this is not something plugins could of been relying on. - Add option (Default on) to cooldown hoppers when they fail to move an item due to full inventory - Skip subsequent InventoryMoveItemEvents if a plugin does not use the item after first event fire for an iteration

Subject: [PATCH] Fix Double World Add issues
|
|
|
|
Vanilla will double add Spider Jockeys to the world, so ignore already added.
|
|
|
|
Also add debug if something else tries to, and abort before world gets bad state
