good afternoon mojang staff sorry for the inconvenience I think I found a possible mistake as my villagers (with his name tag) started to disappear first was one but then half of my villagers disappeared and could not have been killed by a zombie Because I have all of them locked in a mountain a few meters from my house and can only be accessed from an underground tunnel, but returning to the subject the problem is that my villagers disappeared being tagged.

If this is not a mistake, sorry for taking away some of your valuable time
