First reported in MC-248722. This report was made during the Experimental snapshot so it was marked as invalid. This issue still happens in 22w13a.
The bug:
I was going to a bunch of different ancient cities to learn more about the ancient city structures and seeing whats new. I came across an ancient city which was completely destroyed from the generation of both water and lava aquifers.

In both of those cases provided the center structure is not take over by aquifers and properly immersed in deep dark. At this point we have decided not to restrict structures more than it needs to be to keep the center structure dry. The following examples are within parameters we have set for the ancient cities. At this point, the placement of these ancient cities is working as we have intended.
There still IS a possibility for center frames to be submerged, but it should be extremely rare at this point.
Can confirm in 22w14a.
