It is in world some i use i singleplayer, it is from a server and the chunks are loaded before i upgrade from 1,.16.1 to 1.16.2. I has not explore the map so much but i can do more tests.

It is a 1.16.1 world cords -3218 80 -557 and go to -2579 80 -1188

The world is 4,3GB

If i load same seed but is not same file, I get this errors  (is not exactly same world it is different dates, so one file can have more changes, but chunks are loaded before 1.16.1 and first was the chunks around the player loaded in 1.16.1).
