Old Lady 

This myth was one of the first ones to be found because it is a myth of a side quest in the game. In this quest a old lady tells you to go deep in the jungle to find a crashed airplane on wich a relative was on. When you get there you fond out that the place was already 30 years old and that people now lived there. Also there is a man that says there isnt any old lady in the village nearby. When you go back to the spot where the old lady was you find out that the old lady disapeared. Also she says that she saw the plane crashing from her window and yet her house does not have windows. Some players say that you can see the old lady outside an outpost when you complete it and that if you try to take a picture or you get too close you will teleport to an infinite island with nothing but wilderness. This is one of the weirdest myths ever.
