I'm not noticing this with animals but definitely noticing it with my villagers.  Single player world and no crashing.  I leave my village fairly populated and I come back to only two villagers left.  There's so much I want to do with villagers but there's no point in doing so right now. I even created a couple of iron golems that disappeared with them.  

Bedrock version 1.14

I'm also noticing this issue. I don't have a problem with other mobs as the "duplicate" defect is talking about, only my villagers.  I started out with over 20, lose all but two, build them back up then run away so that there's no way possible that there's anything causing them to die and they're still despawning.  I hope this gets fixed asap bc there's so much I want to do with villagers but right now there's no point.
