I downloaded and installed the latest MC update on my PlayStation 4 today (10th March 2021). After about an hour of playing in my world i went to my village only to see that it has become a ghost town. I play on peaceful mode and the village is completely walled off. I lost all my librarians, cartographers, and fletchers. I had 2 librarians that sold me mending, and i had 1 librarian that sold effiency V. I even noticed some of my pets that had name tags have gone missing too.
