Could you be more specific please? We released the permissions feature that replaces ops for Bedrock. What you are seeing, is that happening on Java or Bedrock? Is it still happening?

If any of you download your world and play locally, is the problem persisting there as well?

Very old bug with few occurrences recently in an area we have fixed a lot of problems with. Bug is also too general to act on. If problems persist, please contact Mojang Customer Support.

Could not reproduce in 1.14.2 (Mobs spawned as expected both locally and on Realms)

Please contact Mojang Customer Support directly if you need specific help or support regarding your Realm.

Indeed, the realm will be stopped after no-one has been playing on it for a while (usually about 5 minutes). Then the next time you enter the realm the fix will be applied. If you can not make the realm empty for that long, the best solution are the steps TXLW and Jason listed.

I appreciate your candidness. If you speak to our support staff and refer to this issue they will be able to help you with the request for compensation .

This issue has been resolved and the fix is rolling out as we speak. It will require a server restart to take effect. Thank you for bringing it to our attention and for your understanding in the matter.

A fix is under way. Very sorry for the inconvenience, as Mega_Spud noted, you can temporarily work around this by using commands to op and deop players as necessary.
