Ancient cities can generate so close together that they're touching / indistinguishable, giving the appearance of a massive ancient city with two centers.

Hi; I'd like to request for this ticket to be reopened as this doesn't appear to be fixed in 22w18a. You can use the information provided below in order to reproduce this in this version. MC-249784 - 22w18a.png
Can confirm not fixed. Creating a new world with the original seed (-4958260856419505585), I still managed to find ancient cities that were getting submerged in aquifers.
/tp @s 1669 -33 -16758 120 30
/tp @s 42352 -35 -24530 -19 41
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.
