Hi, 

How / when does the overview map or player position map get updated ? Does anyone know the rules or the mechanism ? Its not clear why I am able to see moving player positions sometimes but not at other times. 

Many a times players are within meters behind a wall and the position map doesn't have any indication even if I can see them in the open ground. 

When / how does the position map get updated ? Is there a way we can force a refresh ? 

TIA
