Hello!
I chose the southern city and played for an hour or so. Finally i ventured just outside of town to the north and died to a bear.
On the re spawn window where it gives 2 choices of last city or Home I chose last city. It then re spawned me to the north city.
Thought I should let you guys know as this can be very inconvenient if you had a lot of play time in and a vault full of stuff in the opposite city.
Thanks!
