• That’s literally what the game already does. But it can’t have all the effects you believe it should have, because there are a lot of events that can change a modifier that would require a recalculation.

    Also marking thing as “should_update” (like you called it here) the way you describe it would cause terrible performance issues. You can’t mark large amount of pops for an employment update, because employment calculations are some of the more expensive ones to do, and doing it for large amounts of individual pops at a time would cause severe lag spikes.
