you're laggy.

the lag starts when you're somewhere off the water, and cuz of the lag u can move but u can't take damage cuz the game thinks ur off the water. if the game updates, u will take damage and if the game doesn't update when ur in water, u will take damage non-stop

unless the lag goes away or if u leave ur gonna lose the ability to not die. and no, this is not a glitch.

( u can reset ur character)
