I was looking for a someone who also has this issue. I play on the current version of Bedrock with the Gravestone add on as well. I placed all my diamonds, emeralds, iron, and gold into a bundle, then the bundle into a chest. I then continued building my house and when I went to go organize my items, all my valuables disappeared and my bundle was empty. This is in a relatively inactive realm, and I checked all player activity. I have been the only one on.
