items missing after dying

[keebruce]

When I die in my server using this mod, then go back to the grave and break it, I always end up losing items.
The grave is in a closed environment so the items should all go into my inventory.
However, while I end up retaining most of my items from the grave, I usually end up losing something pretty valuable.
At one point, it was an iron chestplate and 2 stacks of iron.
At another, it was 10 diamonds and a bundle full of items.
This is a recurring issue that happens every time I die: My most valuable items are deleted for no reason.
Are you gonna fix this problem in 1.21.4? Or is this a dead project at this point since it hasn't been updated in 9 years? I need to know.
