Ref. #34

"After respawning or even at will, items despawn or turn invisible in y<0 chunks"

[Razaekel]

Need to know:

Which is it? Despawning or turning invisible?

Does this also happen when y > 255?

Despawning. This affects all parts of the world including the vanilla boundaries. Also the player is not detectable after a respawn.
