I don't know if this is a feature or a bug, In the game there is a "Generate Grave in Void" configuration, it works perfectly in TheEnd but in OverWorld it's like a bug. Specifically I configured 'Generate Grave in Void = 50', every time I or other players in my server die under Y=-14 coordinates, our graves are always placed at -14 instead of at the coordinates where we died. I think the configuration should only interfere with the void of TheEnd instead of OverWorld, because no survival player needs to go through the bedrock layer under OverWorld.
Version: youre-in-grave-danger-fabric-2.4.16

I'll leave this as a future note for myself when I'm able to take a deeper look at this, but I will likely add a more diversified configuration, mapping dimensions to specific y-values. This way I can also have a set y-level instead of just "this many blocks above minimum y"

This has now been implemented in the newest release of yigd (2.4.17)
