The game seems to have been a bit jittery since Thursday, in particular seeming to hang whilst opening the System Map whilst in Open, a work around is to exit to main menu. The game seems to run just fine in Solo mode however.
I have had this a while.As you say your workaround does work.It is in Solo play as thats all i play.There is another workaround.If you use the system map from the left handside display and it hangs up,exit,restart then use the controller command for the system map and it works fine,it also works if the revers is apparent.The game seems to have been a bit jittery since Thursday, in particular seeming to hang whilst opening the System Map whilst in Open, a work around is to exit to main menu.
