I have a Realm with over 60 users, and random areas of the world are resetting after players build on them! It is essentially destroying peoples builds with chunks resetting. This happened on my first Realm and when I contacted support they recommended me to reset the world. This disappointed all of the players on my realm because we had made a TON of progress and now the new world is facing the same problem. This is a major flaw in the game and you all really need to make fixing this bug a top priority. It has ruined at least a dozen peoples homes on my Realm. PLEASE fix this!
