on the description page it doesnt say what the blocks are to see. i figured out to see tnt i need to do /tracer register PrimedTnt but i cannot figure out how to see falling sand. in factions sand is a very important part of a cannon and seeing it would be very helpful, ive tried to register, sand, Sand, FallingBlock fallingblock, Falling Block, falling block, Falling_Block, falling_block. and i cannot get any of these to show me sand
