How do I enable lost cities generation in an existing world? 1 19 2

[sigmaface1]

In general, I created a world to play with friends, but forgot to enable city generation, I remembered about it only now, and we have been playing for quite a long time and I don’t want to make a new save. Is there a possibility to enable their generation?

That's unfortunatelly not possible. The only thing you can do is make a new world and use some kind of editing tool to copy over your buildings
