The best example i can give and was my test was using this with Infinity Caves. The mod is hardcoded that if u land inthe void to place it on bedrock, but with this if u die below -64 it spawns the grave at -64 not where you died. Maybe make this option a config option on where the -64 cap is.

Thank you

Like to be clear i see the config option but it should auto pull in the datapack value to its best abiulity.
