I don't know where else to ask this question, because when you email support you NEVER get answers. Can you PLEASE answer these questions.
How far from a bed can a villager be and still claim it?
What conditions must be met for a villager to claim a bed
What different ways can a villager unclaim a bed besides breaking it
This is a bug tracker, and not a place to answer your questions.
Try the Minecraft discord or the Minecraft forums instead.
