Obstructives shields and random fall damage

The new update made shields acting weird and obstructive by riding a boat or a horse and after you fire a bow while crouching,and the fall damage are insane i went to the end one time and i was just one block higher amd after the levitation effect is off i instantly took 4 hearts and sometime if u walk in an edge of a block u get random damage sometimes half a heart sometimes nothing so i hope u fix these in the future.
