class CustomBlockDataMoveEvent(plugin: Plugin, blockFrom: Block, blockTo: Block, bukkitEvent: Event) : CustomBlockDataEvent(source)
Called when a block with CustomBlockData is moved by a piston to a new location.
Blocks with protected CustomBlockData (see {@link CustomBlockData#isProtected()} will not trigger this event, however it is possible that unprotected CustomBlockData will be moved to a destination block with protected CustomBlockData. You have to cancel this event yourself to prevent this.
