I was in a survival world, and I had bundles in a chest with ores, and valuable items. I broke the chest they were in to quickly transport them to my new base and the bundles inside with items in it completely disappeared. Everything in the bundles had just gone away and now all my valuable items are gone, but after I did it again to show screenshot, the bug didn’t happen again.
