You can go through blocks with enderpearls, that's very weird on a pvp server when anyone gets into your house and then kill you. Place a block then get under it then right click a couple of times with enderpearl. You will see that you can go through blocks with it. Another enderpearl bug is when you have in front of you a 3x3(3 width and 3 height) or bigger glass panel wall and then right click a couple of times with enderpearls you will see that you can go through it. The same bug is with cobblestone fences and mossy cobblestone fences. Thank you!
