I know a lot of people post about this, but I really do want to see if anyone has found a solution. I have Sequence 11 COMPLETED, and all 11 fast travel points are unlocked both above and underground, but it still says 10 out of 11. Also, whenever I fast travel to the city hall one, I have no torch and an invisible wall prevents me from exploring the rest of the tunnels. If anyone knows how to fix this it would be much appreciated.
