Cities: Skylines Dev Tracker

If you use mods please check your mods against the list of broken mods, both the first tab and especially the tab named Patch 1.17.0. The list is constantly updated as mod issues are discovered, so I recommend checking regularly if you use mods.

If you don't use mods, then please make a report on our support forum so we can look into this. We need to see your output_log.txt (called player.log on Mac and Linux) and your save, which cannot be attached here on Steam.

Yes, like other buildings and paths it does block zoning tiles, but it can overlap with most other buildings and networks.

We have another patch planned to fix more bugs but hopefully it won't affect many mods. So far this patch looks like it only affected a few mods so fingers crossed!

Most likely the update. I recommend you check this pinned post for tips on how to proceed and how to determine if your mods are broken.

You can see which mods are known to be broken and which have already been updated on the Patch 1.17.0 (Hotels & Retreats) tab of this spreadsheet:
https://pdxint.at/BrokenModCS

There have been no changes to Seaside Resorts, the pack still features unique buildings which can be used to attract tourists to your city, who will then stay at your hotels.

Patch 1.17.1-f4 is out.

Latest patch notes

If you do play modded, you will be greeted with a notification when you start the game alerting you that some mods you are subscribed to haven't been created for the current version of the game. Opening the Content Manager will show you which mods were not made for the current version of the game, however, this does not mean the mod is broken. The notification is there to help troubleshoot but to determine which mods are known to be broken and which have been fixed, please see the list on the spreadsheet which can be accessed by clicking List Incompatible Mods.

Modders have been hard at work preparing updates, so please be patient while they apply those to the Workshop and sort out any issues that may not have been found in testing. Check the spreadsheet regularly to see which mods are st... Read more

I spotted algernon released a new mod which may help to remove Extended Managers Library and Prop Anarchy. Note that the mod is still in testing so make sure to read the description carefully.

Simulation failed: EndDeserialize(PropManager) is usually caused by a combination of Prop Anarchy and Extended Managers Library. Make sure you have the updated versions of those mods, and if that doesn't help, I recommend unsubscribing both and getting Prop Control instead.

Where can I find how many assets I use? DO you mean, to how many assets I am subscribed or to how many I use in one city? I have started a new city and the wait is the same even if the city is empty.

Yes that is it. The Loading Screen Mod is likely the easiest way to see how many assets you have installed as Steam subscriptions can contain more than one asset and won't be accurate. With 16 GB of RAM installed you are likely able to have around 500-1000 assets depending on how many DLCs you have. If you're above this, I would highly recommend you reduce the amount of assets you use as Mac controls the swap file and it's high... Read more

How much memory do you have and how many assets are you using?

Let's stay on topic and respectful, thank you!

Originally posted by AntoineBcn: I barely have time to play the game actually since it takes more than half an hour to run it and I am not able do anything else since the whole computer gets very slow but hey, nobody asked you to answer me :)

If your game takes half an hour to load, something isn't right. My guess would be your system memory either doesn't reach the minimum system requirements or you have way more custom content than your system is able to handle.

If you have less than 16 GB RAM I do not recommend using custom content at all and you will most likely need to set up a custom-sized pagefile of at least 32000 MB. You can find a guide on how to do that h... Read more

Unfortunately, we had an issue with the settings file, which stores what is enabled in the content manager, getting corrupted. This issue was fixed earlier today and you should be able to enable the style (and any mods you use) again now.

Originally posted by Quoniam15: Problem persist every time I restart the game, that's annoying. The other part of it is that if I restart the game without verifying the files first, ticking the style box in the Containt Manager does nothing, loading saves still miss European buildings.
Everytime, the game redownloads 8.6 Go of data.
It's as if quitting the game deletes all of that data for some reason.

We are aware of this issue and currently investingating it. I'll keep you updated when there's more news.

We just pushed a fix a few hours ago which resolves the issue with the empty content manager and mods disabling. The update will be applied the next time you start the game and mods will stay enabled.

If you have the 0/0 mods issue, then please restart the game so it can generate a fresh userGameState file and you can start enabling your mods.

We just pushed a fix a few hours ago, which resolves the issue of the userGameState file resetting. It's the one that contains the information about which advisor panels you have already seen. So they should stay closed again now.

Did you remove all your mods or only broken ones?
