After my AI touched the world code, my saved world looks different

You asked for a small change and now the lake you built next to is gone or the hills moved. This entry gives your AI a quick way to prove whether the world still comes out the same, and to name the first place where it does not.

Why this works

A generated world is a pure result of a seed and some rules. Comparing short fingerprints of a few areas is cheap and catches any silent change in those rules before players lose their buildings.

When not to use it

Skip it while you are still designing the terrain and want it to change. Freeze the fingerprints only once players or saves depend on the current shape.
