After the new nether update non of the maps work correctly. They don't record new discovered areas, if the map is brand new it only maps out the basic start area and then stops. They also don't show the players' correct localization - for example shows the players in two opposite ends of the map while they are standing right next to each other or the localization jumps randomly/doesn't move while the player travels. Both me and my sister experience this issue, I play on PC, she plays on PlayStation.
