Loving the map....maybe a bit too much! I've found a weird issue if you try to send an AI worker to the area around field 40 (underneath the bridge)and the vehicle stops above the field, tries to jump off bridge! Also any vehicle returning to the dealership area in the NW from Southwest of the map tries (unsuccessfully) to join the raised highway from ground level and/or attempts to climb the cliffs!
Not sure if any of these are under your control? They're not huge issues and they're the only ones I've found in over 24 hours gameplay. Great map!
