Update: maps continues to break in new and frustrating ways. The map no longer updates and recalculates when I use a different route than the one it outlines at the beginning of my trip. It simply carries on as if I'm still on the original route. This is dangerous and needs updated ASAP. Edit: did everything suggested by developers below. None of which would be necessary if they just, you know... Tested their code before releasing it and hosing Maps
