I have a Minecraft world which I play with friends and in fact, I have it with a Realms subscription, the problem I'm having is that since the last update 1.19.63, it seems that the Minecraft world has suffered some kind of corruption, they disappear building blocks, mobs with nametag, and even objects that are stored in chests in a very random way, this has been happening to all of us within the server, so after a few days after the update, we ruled out that it was some "troll", there is I must add that this started to happen from the update to 1.19.63, this did not happen to us when we were in 1.19.60 or earlier. I would just like to report this error, since obviously I find it difficult to solve our case very promptly, but perhaps this report can be of help to you.
