There is literally no reason for it to be there. The overlay doesn't work and it never has worked. When it did it sucked. Couldn't even use it since the controls were so clunky. Like wtf. Ur character literally does an animation with the map open just let us walk and look at that is that so hard to do???? The maps been broken since the game went 1.0 and there still hasn't been a single attempt to fix it when the solution is right infront of your eyes
