The realm will crash periodically between 5-30 minutes. Progress will be rolled back sometimes up to an hour. The realms frame rate and connection lags before it crashes. This has worsened significantly with 1.21.5 but was occurring in 1.21.4 as well.

I have had this issue as well! My Java realms keep crashing and all the data and our builds is getting lost. Next month I might switch to a server provider since Minecraft servers aren’t really working correctly.. I hope this gets fixed as soon as possible or I will have to take my money elsewhere! Thanks for reading.
