Hello Elvyanix, is your map constantly freezed? If you can 1) enter the world map 2) experience the freezing 3) return to your city 4) go back to the map 5) no longer have the freezing, then that would be the issue that's supposed to be fixed with this update (which we haven't been able to reproduce since then).
If you simply enter the world map and cannot do anything there, then that would be the issue reported
at this link. While similar in behavior, the two would be different bugs.
