We are experiencing the same realm disconnects and rollbacks! Just playing on my own switching some item frames and poof i get disconnected and when i try to log back in i first get an error (an error uccured message) and 2nd or 3rd try i do login to see the world rolled back half an hour... Those login fails always occur since the last week. This happends multiple times a day and is very annoying... Players stop playing due to this and when nothing changes i'll stop my realm.
Same here but on my Java realm. First it takes a long time to see an error occured. 2nd login try mostly is ok but sometimes a 3rd try is needed to login.
