Patch Notes for 1.21.1-f9

Fixed 2
  • Trees placed on roads no longer revert to default trees when reloading the save file

From Cities: Skylines

We have a very small update for you all today that covers the bugs reported to us over the past week. We think that this will be the last one!

This update is very minor and should not affect mods and asset functionality.

  • Fixed a bug where trees placed on roads would go back to default trees when reloading the save file.

  • Fixed a bug where trolleybuses became invisible.

The wait is over, mayors. The anniversary content for Cities: Skylines is live now.

Starting today, you can hit the streets with Race Day, the brand-new expansion developed by Tantalus Media. Build dedicated racing venues, map out running and cycling routes through your city, and line the roads with cheering crowds as competitors speed past your skyline. Whether you’re designing a professional circuit or weaving a course through downtown, it’s time to bring a new kind of spectacle to your city.

Also available today:

Alongside the paid content, a free patch is now live for all players, adding road fences and a new Employment Info View, giving you clearer insight into how your workforce keeps the city running.

Everything launching on March 10 will be available separately, or together in the Race Day Bundle for $23.75 / £20.15 / €23.99, which saves you 18% if you want the full set.

Update your game, load up your favorite save, and let the celebrations begin.

From Cities: Skylines

Hello Cities Mayors,

We are thrilled to announce that we have brand-new content for Cities: Skylines, developed by two amazing Content Creators, all implemented by our talented partners at Tantalus! This content has been in the works for some time as we know many of you still love building and expanding your cities in the original Cities: Skylines. Whether you’re a long-time fan or just discovering the game, these new additions help expand the range of your cities, with a Mountain Village Pack and Map Pack 3 with new maps that focus on mountain peaks and alpine terrain. Plus, for those who love the sounds of trees whispering in the wind, the Radio Station Alpine Tunes can accompany you on your next trip to the mountaintop.

We also want to reassure those of you that play Cities: Skylines II, that the development of this new content for Cities: Skylines is an entirely separate effort. The content you’ll find in this release for Cities: Skylines has been implemented by Tantalus, the studio who managed the console ports for Cities: Skylines. No resources were diverted from Cities: Skylines II for this - our friends at Colossal Order remain fully focused on developing and improving Cities: Skylines II. This approach allows us to release some updates without compromising on either game.

So, for those excited for news around Cities: Skylines II — if you missed the earlier entry about the roadmap for the first region packs, we are almost done with the implementation of the first pack and it will be out next week!

Join us on our trip around the world https://www.paradoxinteractive.com/games/cities-skylines-ii/modding/cities-skylines-ii-region-packs - and look forward to great experiences for many years to come with Cities: Skylines II.


Thank you for being such a vital part of this journey, whether you’re playing Cities: Skylines, Cities: Skylines II, or both! We look forward to seeing what incredible new mountain villages you bring to life with this release!
