Things are disappearing from people inventories on my Realm. My friend logged on and his elytra was missing. Another friend logged on an his elytra and fishing rod were missing. I had a nether star in my inventory and like 1 minute later I noticed it gone. My friend also briefly turned invisible for me and my other friend online. I am also unable to breed my 2 cats. They both get hearts and are standing next to each other but they wont breed. I have no idea what to do and am very disappointed as I payed for the game and am paying monthly for this realm. Plz help
