Feature request: Explanatory messages when DeathChest is not spawned

[SlimeDog]

On player death, player was transported to the expected Graveyard and gifted a DeathCompass, but no DeathChest was spawned and the player inventory remained intact. src list reported no DeathChests. No errors were reported in-game or in the log.

The problem was gamerule keepInventory set to false. gamerule keepInventory true resolved the issue.

So, feature request: Report to the player and the log why a DeathChest was not spawned.
