Let a failed harvest raise prices in the towns around it, less with distance

One town loses its grain and the price of bread rises there, but the town two roads over stays exactly the same, which feels dead. Here is how to let the shock spread along the roads and fade, and what to do when two troubled towns lie near the same market.

Why this works

Trouble travels the way trade travels: through the roads, and it thins out as buyers find other sellers. Letting the shock fade with distance, and taking the strongest cause rather than adding them, matches how markets absorb bad news.

When not to use it

Skip it when the player's own actions set prices, or when a town is cut off by a blockade or a sea. The spread would then send the news along roads that nobody can use. Set prices town by town by hand there.
