Game Crashing After Deleting Default Royal Families - Save File Unplayable

Thank you for testing my save! Let me clarify a few things:

1. What exactly happens when the game crashes?

When I select the new DLC world from the Manage Worlds screen of the corrupted save, the game closes completely before the loading finishes.

- With MC Command Center installed:A lastException error pop-up appears right before the game closes.

- Without any mods: The game still crashes to desktop, and a `lastException` file is generated in my documents folder (the same ones I attached in my previous replies).

2. How did I create this test save?

I first disabled all other expansion packs  in the game's pack selector, then disabled all custom content and mods  in the in-game settings. After that, I created a brand new save file with only *Royalty & Legacy* active. The only action I took was deleting the default families — no other gameplay.

Just to clarify: the original crash happened when all my expansion packs were active — that's the save where I first deleted the default royal families. The clean test save I sent you was created with only Royalty & Legacy enabled and all mods disabled, just to confirm that the crash isn't caused by mods or other pack content. Hope that helps!

3. Additional observation:

I've tried loading the save multiple times myself.  Occasionally (1-2 times out of many attempts), I actually succeeded in entering the world. But most of the time, it still crashes. Currently, I have  four identical lastException files  in my documents folder from these attempts.

Hope this helps! Let me know if you need me to test anything else.
