So i was about to raid an ocean monument but i didnt had a lot of time cause of lunch.

I made myself a small mini base where i could spawn and i stored my armor and other things like netherite picks, axe, shovel, elytra... In an shulkerbox and the shulkerbox in an enderchest so it is save if i would die. After that i turned of my ps4 and did some other thing.

A couple of hours later i turn minecraft on, and my shulker box with everything inside just disappeared completely while it was in the enderchest.

Anybody an idea what i can do to recover my stuff cause i stored everything in there thinking it would be safe and im really not in the mood at the moment to grind all over again to replace all of it.
