Describe the bug
L63-65 of Graves.java has the following code:

if (pos.getY() < 0) {
  pos = new BlockPos(pos.getX(), 10, pos.getZ());
}

This is an issue because the world has been moved down to y-64.

Forgotten Graves Version
v2.0.0

Expected behavior
It should generate the grave at y-60 as opposed to y10 and have a minimum Y level of y-64 rather than y0.

This will be fixed in the next update (which should release later today or tomorrow). I'm finalizing up a feature and then it'll be good to go.

This has been fixed in 06720b6 and 75e0bce.

Closing.
