Java and Bedrock are not made to be identical. This seems more of a feedback / suggested change than it is a bug report.

While there may be a chunk issue, I've lost an expert level mending librarian about 4 or 5 blocks away from the chunk border at his closest reach.

I created a village of 3 buildings with 4 villagers. I've been having a constant issue with villagers despawning. Originally got up to 3, 2 disappeared, so I went and grabbed more, the last one of the remaining 3 despawned. I consistently had this issue and I lost track of who I lost and who I kept. I built an addition to the side that ended up allowing villagers to stand on the wall and I wasn't too worried about it. At this time I had three villagers all brought in from the same grouping of zombie villagers.

I then some days later I grabbed another zombie villager for a mending librarian. I locked this one into a house. He had 7 total blocks within his blocked off area. The closest block that he could stand on to a chunk border was 4 or 5 blocks away from either horizontal chunk border. Of his 7 total blocks within his area, two were used up for a "bench" made of oak planks with a brewing station atop one, the workstation for librarians (escaping my mind right now) is taking up another block but not on the ground, just floating. and then of course he had a bed in there. this area is 2 blocks high.

I do have a Nether portal within render distance, although I can't recall this last time whether I had recently used it.

The odd thing I've noticed is that with this last group, the villagers I brought in three at a time, all vanished at the same time. The librarian remained and I assumed it was because the other three could get up on the wall. I now assume that the same amount of time between when I cured those three and then cured the librarian, is the same amount of time it took for the librarian to despawn although this was not me actually testing it out but rather just trying to play and these are the observations I made.

I wanted to throw this in to make the point that the chunk border didn't have anything to do with the last one although it could've with the other three if this were caused by two different issues.

Edit: Forgot to mention, I am playing on Xbox One.
