Describe the bug
When playing on a multiplayer server with MCA Reborn installed, my married villager and my child vanish entirely from the world. According to the MCA family tracker they still exist at their last known coordinates, yet physically they are nowhere to be found (See screenshots below). They are not listed as deceased in the civil registry, no death mails have arrived, and even the /tp command returns “No entity with that name found”. The mod’s whistle fails to summon them, and there are no viable exits in the building where they are, so escape isn’t possible. This disappearance appears to coincide with a server crash after it was under heavy load, though I can’t be absolutely certain. This issue also seems to occur in singleplayer according to my friend, however, he was unable to give me details, logs, or reproduction steps.

To Reproduce
This reproduction steps are heavily approximative and may not always work, or even not work at all, due to variability in server conditions and crash circumstances.

1. Be married to a villager and have a child via MCA Reborn.

2. Crash the server by overloading it (e.g., large structures or many entities).

3. Restart the server and rejoin.

4. Observe that the spouse and child no longer appear in the world, despite still being somewhat-alive in the tracker and other things.

I'm not sure how to resolve this. Crashing the server leads to data loss, this is a general problem and not related to MCA.
