  • MC-266586: May make these intersections more likely, but a fix would not eliminate the issue since structures can (and do) intersect ancient cities after beginning their generation from outside the deep dark.

MC-266446 doesn't quite meet the criteria for issue relation but is worth keeping an eye on, since if it were fixed, the nature of the trial chamber-ancient city interaction could be affected, potentially negatively.
