I own 3 realms. Two of which rarely decide to work. I've added a few add-ons to them and they work perfectly fine. A few days later the realms don't let anyone connect anymore. I reset the world and it's perfectly find again. Sometimes closing it and opening it fixes the problem also. But I'm now trying to replace the world but I get an error Message for everything. Whether it be changing the name, removing or adding a addon, resetting the world, replacing the world, downloading the world, changing settings, connecting, activating another world, changing it to a backup, or even making it required for players to accept resource packs. Everything gives an error. I've taken everything off and pressed reset in which it said it went through and worked but I can rarely connect and when I do connect it's the previous world i had on there. Also when trying to replace the realm it will give an error but still rename the world to the new world name yet having the previous world in it.
