CreateEncyclopediaPages crash on loading saved game with custom kingdom and settlements

[sinkpoint]

Hi all,
I'm creating a mod ( 1.5.8 ) with a new custom kingdom and new settlements on the Main_map.
So far everything works fine on creating a new game, but as soon as I load a saved game, it crashes.

I've been scratching my head, as I've compared with multiple custom kingdom mods and I can't see what I'm doing differently.
Reducing the mod down to a single clan and hero still causes this.
Anyone have dealt with something similar before?

The stacktrace is

Thanks!

Ok I solved it.
It's because there are missing culture definitions on some mintor NPCCharacter defs.
Double-check that all ids have actual definitions referring to them.
