Unsorted

 * Crossbow handling mechanics are different. In Java, the arrow will only load onto the crossbow when the mouse button is released; holding the right mouse button will then fire and charge the next arrow. In Bedrock, the crossbow will automatically load the arrow when finished charging; holding the right mouse button will then fire but not charge the next shot until the player clicks again; charging the crossbow will take an item damage.
