Mojang are aware of the issue (see this comment) and are working on it.
Please limit comments to information about conditions that seem to result in a disconnect. Comments that do not add information may be removed.
From some of the duplicate reports, one or more of the following actions consistently produces the disconnect/rollback for some realms:
- Specific player logging on
- More than one player logging on where either one can play fine separately
- Having large number of villagers in an area, if approached or player relogs there
- When the realm does its auto-save
- Traveling between dimensions
We started playing on our current realm a couple of days ago and everything was working without any hiccups. Today however the realm suddenly starts to perform resets and to load the world, it falls back on slightly older back-ups. At first it was a one time thing, but about 15 minutes later it reset itself three consecutive times. We decided to leave the realm alone for the night and see how it performs tomorrow.
We'd like to know what could be the cause of the sudden resets.
UPDATE 15/01/2021 : Logged on this morning and so far it seems okay. Will keep you posted through the coming few days
UPDATE 17/01/2021: Realm still hasn't performed a reset since 14/01/2021. I'll keep updating 'till the 21st of january
Update 21/01/2021: So far still no problems found since the first ones. Will update again only when Reams start disconnecting everyone again.
