Every so often during gameplay on my realm, the game will suddenly kick all players out and, when re-entered, will have reverted to an auto backup from about 30 minutes ago. This is extremely annoying.
What I expected to happen was...:
This issue to not occur.
What actually happened was...:
Progress loss.
Steps to Reproduce:
1. Open Realm, join world
2. Play for some time, wait to eventually be kicked (doesn't always happen)
3. Rejoin world, witness what has been lost.

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.

ive had this happen on my friends realm 3 times now. the server is always laggy right before the "crash" happens, and the game rolls back to the most recent save. the first time it happened, 4 or 5 people were on, 2 of which (me included) were loading new chunks in the overworld. i decided to stop playing at some point, and when i logged back in i was at the village i stayed at during the night (i guess that would be where the last save was), and i found out one of my shulkers got duplicated (1 was in my ender chest whilst the other was placed because i was sorting stuff out). probably something to do with the data thats stored in each save i guess? the 2 other crashes happened today, whilst roughly 5 people were on max at some point for the second one and on the 3rd only 3. i'm not fully sure till which save it goes back to, since i'm not the one that pays for the realm. the only major progress loss we've had was on the second one, since everyone was busy grinding for materials or building, which we all lost a part of after the server came online again.

Having the same issue. I love realms but if this continues I will cancel my subscription
