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.

1

Check the gameplay impact

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

2

Review stability notes

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

3

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 v1.4.12

  • Fixed vehicles leaving the road while turning from a two-lane road onto a four-lane road.
  • Improved vehicle interpolation and low-frame-rate handling to reduce stuttering and apparent teleporting.
  • Reduced rendering work from unused construction scaffold/crane slots and unnecessary building updates in stationary views. Existing quality settings are preserved.
  • Removed the automatic Japanese building skin promotion and fixed completed tutorials reappearing on reconnect. Improved saved music-off settings and remember-me behavior.
  • Fixed saved building rotation and footprints, size hints, rooftop add-on saves, and public-building move cancellation. Reduced false conflict notices from overlapping saves in the same tab.
  • Fixed sewage connectivity checks for rotated facilities and multi-tile buildings. Coastal water pumps and wastewater plants now have a 10-minute construction time.
  • Improved road-access checks after demolition and menu switching; prevented add-ons on railways and zoning on blocked terrain. Improved warehouse priority selection and last-save time display.
  • Restored the playable city trial for visitors who are not logged in.
  • Improved the shop payment-provider selection dialog.
