I got a bug where I hit a wall south and north from platform in Vulcanus. I have been on the same map now for maybe 2-3 hours and not getting a randomly new one. I can go far on both east and west sides but having trouble to get Tungsten because of it. I think the bug may have occured when I had the overlook (M) activated at the start of arriving to the planet.
Hopefully it might be the Ribbon world with the same seed combination that makes it be like that. I will be continuing playing and update if the seed changes.
