The destination is buried underground.

We have recently received numerous reports from players stating that the coordinates they are directed to—serving as objectives or waypoints—are frequently buried underground (i.e., the Y-coordinate is below ground level).
While we understand that such issues can occur when using custom maps, this problem is particularly prevalent with the current map (https://codefling.com/maps/oil-point-custom-map-by-shemov).
Is there any way to mitigate this issue?
For instance, are there settings available to ensure coordinates are always placed at or above ground level, or options to adjust coordinate placement based on the specific map being used?
