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 v1.4.50

Coal, oil and ore extraction facilities now show a sad emoji when neither the facility nor its extractors overlap the matching deposit, leaving extraction at zero. Hover over or tap the bubble to see the reason.
Refined emoji bubbles so their tails join the outline smoothly, with softer corners, updated colors and improved shadows.
New Grand Canyon cities now have starting roads on both sides aligned in a straight line with the central steel arch bridge. Existing cities keep their road and bridge layouts.
Fixed shallow canyon edges being mistaken for obstacles that blocked bridge placement on Grand Canyon. You can now build and save a bridge directly in line with the starting roads on both sides.
Softened the stepped color boundaries and dark shading along the central canyon rim, blending the ground more naturally into the cliffs.
Grand Canyon's loading screen now uses an in-game view of the canyon and steel arch bridge with the same composition as its map thumbnail.
