Roads would save from previous generation, it wasn't always perfect but that's fine.
I'm not sure how to explain it well, but I think the short version is, it's not just one city, is every city on the Azgaar map I have. There are 441 settlements, and even the ones that I have opened up weeks ago in the city generator seed and saved, are also now all changed (which I thought ahead as I built them the first time and did export them all so no big deal there). I will try to use pictures to help me out.
I have opened the map on a few different browsers as well to see if maybe Chrome is upset about something, but that doesn't seem to change it either.
This is what the preview will show for example
And here is what the generator will show when I open the "See in City Generator by Watabou" link. No walls, no plaza, no shanty town and 4 roads when I have it preset to 1 road.
