Does that mean that there were no foreign key checks in the AI sql schema? That seems like a hilariously stupid thing to not do.
It's not real RDBMS, that would be too performance-expensive. A lot of games use relational data without having full RDBMS (Total War games, for example). Although I'd spend some time to develop data sanity check tools for developers and modders to be run outside the game.
