This code is fixed now, so...
Town Map Teleport:
Open your menu, go to the map of the town, and hold L. While holding L, use the dpad buttons to maneuver the cursor to a location on the map (anywhere is fine)
And then press A (while still holding L)
You'll be teleported to the location you chose.
Works online and offline and in other towns.
