Patch Notes — Version 1.3.6f1

Key changes

• Higher noise output from zoned industry:
  Industrial zones now generate more noise and the effect reaches farther. New cities should provide greater separation between industry and residential areas; existing cities may require rezoning of homes that are too near industrial activity.
• Population adjustment when loading saves:
  You may notice an initial population drop on loading older saves. This is the result of corrected citizen-count calculations — figures will update when the save is loaded and should settle within roughly 5–10 minutes.
• Increased truck traffic:
  Resource balancing and the change that allows deliveries to reach buildings before they level up will temporarily increase freight traffic in existing saves. Traffic should normalize once waiting buildings receive resources, though you may need to address congestion hotspots in the meantime.

Known issues

• Fish quantities are not shown correctly for custom maps — this affects the New Game map picker and the Info View in both the game and the Editor. The underlying fish resource is still simulated and functions normally despite the UI omission.
