It struck me when I started being interested in geography of Faerun and looed at maps, to see where game events are located.

On the maps I found online and even on this very forum, Whole Act 1 setting, Moonrise Towers and the city of Baldur's Gate(as well as Elturel) are located on the same, north side of the Chionthar River. So why does our team arrive in Rivington on the south riverbank when transferring from Act 2 to Act 3 and has to pass through the Wyrm's Rock Crossing? What do you guys think? Please write if I missed something about the location of the places I mentioned.
