Sometime today, my friend and I were playing a world, and we made a chest room. We joined then later in the day and found some of our chests disappeared, and we couldn’t access them. We then found out that we couldn’t get our stuff back. They were items like enchanted books, fish, armor, seeds, cobblestone, and wool. We replaced those chests with new ones since the only thing we could do was break them, but all of our stuff was gone. We also noticed around our base that some of our banners did the same thing, and we could break them, but not get them back. Our furnaces as well we couldn’t access, them but they were still visible. I hope you can fix this problem, because we worked pretty hard for all our stuff, or just at least give us some advice. Thank you!
