me and my girlfriend share a world, she plays on pocket edition and i play on a ps4 console. in her world we had two netherite chest plates, two netherite boots, and one netherite helmet displayed on two armor stands. when we logged into our world yesterday the armor and the two armor stands had disappeared. today when we logged in a diamond sword and diamond pickaxe that was in my girlfriends inventory had disappeared as well and we are certain that she had it in her inventory when we had both logged off.
