The issue is on a Minecraft realm. The Minecraft realm rewinds by five minutes to an hour after everyone logs off randomly. From what I understand it only happens after one player plays for a while and doesn't seem to happen after several players leave. The owner of the realm and I have tried fixing it but we don't know what's causing it.

The realm world is 2-3 years old and we believe this issue started after 1.16-1.17

If you guys are able to patch this that would be amazing.

Thank you!
