What were you doing before bug occurred: Getting chests from the underwater crypt ruin thing.

Air for breathing underwater script are probably server sided to prevent exploits. So, as long as the server thinks you are underwater, even if in your client you are outside (such as when lagging), the script will keep going and you will keep loosing air. If this is the case, Vetex can’t do anything about your internet lag.
