What These Updates Cover

Each note is written to explain the player-facing result first, then the design or technical reason behind it. This keeps the update history useful for returning mayors, new players, and search crawlers reading the site without launching the game.

City Systems

Road access, utility coverage, zoning behavior, taxes, happiness, public services, and the rules that shape city growth.

Performance Work

Model loading, render cost, cache behavior, and mobile-friendly changes that keep the city playable on modest devices.

Player Guidance

Short explanations of how each change affects city planning, budgets, service placement, and early-game decisions.

Community Feedback

Comment threads collect bug reports, balance reactions, and requests so follow-up work can be tied to a specific version.

How To Read A BuildCity Patch Note

The update log is organized around practical questions a player would ask after returning to a saved city.

Check the gameplay impact

Look for changes to money flow, service coverage, roads, zoning, happiness, and city rank before changing a long-running layout.

Review stability notes

Performance, loading, cache, and save-state fixes are called out because they affect browser memory, network requests, and older devices.

Use comments for follow-up

If an update changes your city in an unexpected way, leave feedback on that version so the report includes the right context.

Version v1.4.43

Fixed the Create button giving no feedback when the city name was empty on a 500-gem map. Required input guidance and the total map and slot gem cost are now shown, and you can retry after cancellation or errors.
Map selection now calculates resource gauges and railway and coast availability from the actual template. It shows resource tile counts and their share of the map, including zero resources and absent railways or coasts.
Fixed the template-not-found error when overwriting White Sands Coast in the map editor. Saving under the same name preserves existing map unlocks.
Added Ctrl+Z undo and Ctrl+Shift+Z / Ctrl+Y redo to the map editor for tiles, resources, bridges, entry and exit points, and environment settings.
Cities created on White Sands Coast or edited 112×112 maps retain their original terrain when the template changes, preventing later map edits from blocking existing city saves.
