it seems like over all structures are getting in the way on the cities... like MC-249759

The core problem here could be that mineshafts and ancient cities can generate overlapping one another. Here's an example of this.

May I suggest combing this with MC-249759 into one bug explaining how seemingly any structure can overlap ancient cities? Because Not only can lava lakes create holes under Ancient Cities, but even Amethyst Geodes can generate into the walls of cities and break them. Here's one that's generated right in the entrance of the redstone room, butchering it

If not I'll make a new bug report specifying geodes
