se the Risks overlays often to spot problems before they become crises. Red is bad; the more red you see on a pillar, the worse the risk is.

Select Fire to see the city's prefectures and all of the prefects walking their routes. Buildings with tall columns on them have a high risk of fire. As prefects walk by buildings, you can see the risk of fire column fall. Watch the progress of your prefects for a minute, and see if they eventually pass by the buildings with the highest risk. If not, either redesign your road network to allow better patrolling, or build a new prefecture near the danger zone. The Risks: Crime Overlay works similarly, except that prefects cannot lower the risk of crime - they are shown because of their important role in dealing with criminals and their handiwork.

The Damage Overlay works the same way, except that it shows engineers and engineer's posts instead of prefects and prefectures . Buildings with tall columns are unstable, and in imminent danger of collapse.

The Problem Overlay is one of the most useful of all. It shows only buildings that aren't presently working properly. Reasons for the problem can include lack of road access, lack of labor, lack of water, lack of raw materials or lack of space to send their cart full of produce. Scan this overlay once every few game months, just to see if your street-level reviews have missed any problems.

If your province is home to any native peoples, the Risks overlay includes a report called Natives. With this overlay selected, you can see the land the barbarians consider to be theirs.
