[2023] new patch today 24th march

If you use mods please check your mods against the list of broken mods, both the first tab and especially the tab named Patch 1.16.1.

If that doesn't help or you don't use mods, please make a thread on our support forum. We need to see your output_log.txt (called player.log on Mac and Linux) to be able to help, which cannot be attached here on Steam.

Depending on your operating system the log can be found here:

Windows
\SteamApps\common\Cities_Skylines\Cities_Data\output_log.txt
\CitiesSkylines\Cities_Data\output_log.txt

Mac OS X
~/Library/Logs/Unity/Player.log

Linux
~/.config/unity3d/Colossal Order/Cities: Skylines/Player.log

Not in this update no, this was just a hotfix to address the issue with mods. But we're aware of this issue and investigating it.
