I had the same problem,now as for the 2 Chestnut Ridge neighborhoods I think that's a EA problem. I will tell you what I did because now I can finally travel in and out of Chestnut Ridge. First of all I took out my mods and I made sure no active Sim is living in either neighborhood then I exit my game and did a repair through the EA app and this is was solved my traveling problem. I really hope this helps.
I tried this. I still can't get it to work
Same. I tried as well. I removed my saves, and mods, and tray. Opened a new clean game, saved, exited the game, and repaired the game. Opened the game and Chestnut Ridge is still not available for me to travel into.
