There is this glitch where i am able to go through block with a 1 block height, this is real bad because i went to the end and took the portal to get more shulker boxes and the shulker levatated me up through a block which the height was 3 blocks high and when i fell that 3 blocks high, i took 10 hearts of damage and died and lost all of my good gear. I went up 3 blocks high and died with full health from that height by going through the celling. The glitch is i can go through blocks and take damage and  i can go through 1 block height without any water
