Commenting to advise this has happened when transitioning from 1.15.2 to 1.16 (20w06a). Removing a previously /op'd player from operator status appears to have restored the ability to break blocks.
With the message below, its triggerd when a mob entity in this case is teleported from its spawn location
[22:21:15] [Server thread/WARN]: Mismatch in destroy block pos: fp{x=-11290, y=67, z=14439} fp{x=19, y=65, z=-67}
Can confirm in 1.20.1. Also, this has nothing to do with spawn protection and occurs in the entire world.
Having the same ?issue? on 1.20.2. It is definitely related to the spawn area. I can move/destroy/place blocks outside of the spawn area. Roughly 20 x 20 block area.
Cannot break the crafting table, Sign on it, adjoining anvil and double chests in front of them all in one 2x2 square.
Server was started on 1.19.
Items aformentioned were there since 1.19.
Admin and user cannot break the items
