My villagers are despawning. 

there is an issue with villagers despawn , villagers that i’ve interact with ,trade with and even villagers that i named . breed villagers are also despawning . The villagers aren’t being killed by other mobs because they are underground. they all have bed , work stations, and players that have traded with them and yet they keep despawning .

please resolve this issue it’s really annoying to lose villagers with good trades.

Sincerely , an annoyed player .
