Players on the server i play on are having issues with the NPC just randomly despawning.
This has caused issues with marrages and Children.

Are there any commands to get divorced/find child?

The Whistle will immediately teleport all members of your family to you, and the Divorce Papers will allow you to divorce a villager. However, if they have despawned, that's a problem.

I am having a similar issue, the developers have not replied yet.

It appears they have despawned. Wish there was a command to divorce/remove family.
