Let me start by saying I play on an official extinction pve server on ps4. I've had this problem for a while where my player/mini map resets constantly I have half the map uncovered but each time it resets. I read somewhere that if you go into single player on the map your playing and admin command "player command Ascend2" it rolls credits and kicks you back to the main screen. But when you go back to the official server your map is blank, but it doesn't reset.
I just tried it, and my map is blank, even though before it was half discovered. I placed a pin, and exited the server. Got back in and my pin is still there. So I'm hoping this is the fix everybody has been waiting for
