In response to the release of 1.16, I download my Realms world and deleted my DIM-1 to reset my nether. After-which I installed more datapacks. Then I backed up and loaded my world into 1.16. I then uploaded the world into Realms. After playing for around 5 minutes my Realms kicks me from my server stating, "Server Closed." When I head back into my world my progress for the past 5 minutes is reset.
