the mine carts in my guardian farm keep disappearing as well the whole area they are in is in a ticking area so they continue to run but every time i come back they have vanished
having the same issue did you ever get an answer?
i'm just commenting so i can keep an eye on this as i still can't get simulation distance above 4 on realms.
also i'm using minecraft realms on the xbox there appears to be no way to add that as a version
I can verify that this is a pretty big issue. I work as a dev with a large multiplayer server, and we use (Old) Username -> Name history to unban users after verifying that they have changed their explicit/inappropriate username. Hoping its fixed soon so we don't have to redesign our solution.
