I recently got villagers on my realm and we put in the basic breeding area. We were breeding them but one day we noticed that some of our villagers were gone, at first, we thought it was a zombie we lighted the area more and went on with our day but they keep on disappearing. So then I decided to go and watch them for a full Minecraft day. When it got dark and they went into their beds they kept moving and went through the wall I tried to dig through the wall to find them but they were gone. this only started happening when we got the new update 1.16.100. Please help I don't want to lose all my villagers.
