Massive glitch

IF YOU GUYS WANT A BETTER EXPLANATION PM ME YOUR INGAME NAME AND GO ONLINE ONCE YOU DO, IN THIS ALL I TELL YOU IS HOW TO SURVIVE IN THE WATER ON WAVERIDER!
Ok, first off you do the stair glitch at waverider (pic 1)
Then you walk across the side till you hit the tunnel (pic 2)
Then you jump into the water, you will not die, why? I have no clue. (pic 3)
Then you go under the tunneland go till you look up and see a little grass patch, by then, you can turn to face the right way and you will see 1 square floating and if you go towards that.... Ill let you guys figure that out on your own. And Ill give you some pics that prove its real.
In this photo I am on the road behind all the buildings, to get here, pm me and Ill show you in game, Reason im doing this? Nexon will patch if they figure out how.
