Cities: Skylines 2 Marks Six Months Under Iceflake Studios With 200+ Bug Fixes
The team also confirmed that another patch is in development and its first DLC will be discussed later.

Iceflake Studios has reached six months of development on Cities: Skylines II, and the team used the latest City Corner to review the work completed since taking responsibility for the game. The studio said it has fixed more than 200 bugs and added over 40 features and improvements since January.
Iceflake marked the milestone in an official Steam announcement, explaining that its main goals were to address long-running problems, improve the player experience, and build a stronger base for future development.
Six months of updates
The first major update under Iceflake was First Frost. It targeted several simulation and quality-of-life problems, including death waves and bicycle usage. The update also improved nighttime visibility, weather, fog, terraforming, tree placement, and the user interface. Players received the Color Customization tool as an early way to change the look of their cities.
The Anniversary Update added a road-zoning toggle, one of the features the community had requested most often. That gave city builders more control over where development could take place. The update also introduced the Iceflake Arena, expanded gameplay options, and added the in-game Encyclopedia with information about the game’s systems.
Spring Cleaning turned its attention toward city management and interface customization. Its Historic Building option let players preserve selected buildings instead of allowing them to upgrade automatically. The patch also added UI transparency and scaling controls, both of which had been requested after an earlier interface redesign. Iceflake said it continued working with the Paradox Mods team on mod management and download improvements during this period.
The Morning Dew update focused on day-to-day city building. It expanded asset filters, improved workflows for creators, adjusted tool behavior, and fixed problems with shadow rendering. Traffic pathfinding also received behind-the-scenes changes, including fixes intended to reduce unnecessary vehicle behavior and improve the simulation.
Most recently, Summer Solstice brought a major visual pass for terrain. The update improved terrain rendering, shading, depth perception, and the overall appearance of landscapes. It also added terrain painting tools for both the main game and the Editor, allowing players to paint and blend ground textures directly.
Across these updates, Iceflake said it also worked on performance, stability, and simulation issues. The studio pointed to the Benchmarking tool from Spring Cleaning as an early step toward better performance testing. Other fixes addressed problems such as stuck citizens, incorrect demand bars, interface icons, and flickering shadows.
Where the fixes went
Iceflake’s bug-fix breakdown shows that UI and interface work made up the largest share at 23.9 percent. Gameplay and simulation accounted for 19.9 percent, while text and localization represented 14.6 percent. The chart also listed mods and Editor issues, crashes and freezes, art and assets, graphics and visual problems, and other fixes.

The feature and improvement chart paints a similar picture. UI additions and polish made up 27.3 percent, followed by visual improvements at 22.7 percent. Gameplay and mod and Editor tools each represented 18.2 percent, with the remaining work listed under other improvements.

Examples included in the feature count were the Historic Building option, the Benchmarking tool, the Encyclopedia, and Iceflake Arena. Iceflake also pointed to education-system rebalancing, cycling-policy changes, and performance work as part of the broader improvement total.
What comes next for Cities: Skylines II?
The next patch is already in development, but Iceflake said it will be lighter on new content. It will focus on bug fixes and several simulation tweaks. More details will arrive in a future City Corner dedicated to that update, so the patch is still upcoming as of July 23, 2026.
The studio also confirmed that it has been working on its first DLC. Iceflake did not share details or a release date, saying more information will come when the team is ready.
