Whenever I go to God Wars Dungeon, before I enter the Saradomin or Zamorak area, I need to turn on
"All Heights" so that I can see the agility course or ice platform that leads to the God area. If I don't do this, I can't get to the area. If "All Heights" are off, it's just a blank light brown space in the area where the agility course or the ice platform is.
Is it a bug, or was it intended?
