Share your Cities Skylines log file

Verified: February 2022 - TM:PE 11.6.4.7

Check the Compatibility Report first

About 50% of the error reports we get are due to old / broken / incompatible mods. The Compatibility Report mod is the fastest way to find known problems with your mods - it's a collaboration between end-users and mod developers to help navigate the vast array of mods that are out there.

Why we need the log file

The log file contains detailed information about any errors that have occurred, and that helps us determine where to look in the code as a starting point in our bug-fixing investigations.

Details of how to share log file are posted near end of this page.

Log file names

We always need the game log as it contains hardware details and detailed error reports:

• output_log.txt (Windows)
• Player.log (Mac / Linux)

We also need:

• TMPE.log - usually in same folder as game log (see TMPE.log for details)

Log file locations

Location depends on operating system...

Windows:

The game log is called output_log.txt. Location depends on the game portal you use to play the game (click portal name below to show paths):

• Steam

  <SteamFolder>\SteamApps\common\Cities_Skylines\Cities_Data\output_log.txt

  The <SteamFolder> is usually found at C:\Program Files (x86)\Steam.

• Epic

  <EpicFolder>\CitiesSkylines\Cities_Data\output_log.txt

  The <EpicFolder> is usually found at either C:\Epic Games or C:\Program Files\Epic Games or C:\Program Files (x86)\Epic Games.

• EA Origin

  <OriginFolder>\CitiesSkylines\Cities_Data\output_log.txt

  The <OriginFolder> is usually found at C:\Program Files(x86)\Origin Games.

Apple Mac:

The game log is called Player.log and can be found at:

Users/<username>/Library/Logs/Unity/Player.log

The <username> folder is normally your login name.

Linux:

The game log is called Player.log and can be found at:

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

Custom location

The location of the log file can be changed with the -LogFile launch option (standard Unity feature). The TMPE.log will be also placed in the same folder.

Mod developers: See PR #1151 for how we did that.

Obtaining list of mods

• If using TM:PE v11-alpha3 or above, a list of mods can be found in your TMPE.log file. In the list, an asterisk (*) denotes enabled mods and exclamation marks (!) denote mods which are known to be incompatible with TM:PE.
• If using TM:PE v10.21.1 or earlier, subscribe and enable the Mods Listing mod; it will add the list of mods to the game log file.
• If you want an HTML file that lists mods, subscribe the Stream It! mod (read workshop page for details of how to use it).

Sharing your log file

Where are you contacting us?

On Steam:

Log files are too big for Steam, so you'll have to upload the file somewhere. Here are some upload sites that people commonly use:

• Drop file on to panel at Uploadfiles.io - free, no sign-up, can handle large files
• Paste contents in to Paste.ee or, if file is too big, use ZeroBin instead
• Google Drive (how to upload?, how to share?)
• DropBox (how to upload?, how to share?)
• Do NOT use: Pastebin (too small size limit), Dochub (very slow to read files)

Make sure the file is publicly viewable, then share the URL in a comment.

In Discord chat:

Drag the file in to the #support chat window to attach it. Also tell us why you're sharing the file, otherwise it's just a random file and we have no idea what we're looking for.

On GitHub:

On your issue ticket, drag and drop your log file in to the large text box. Wait for it to upload (the text will change from [Uploading ...]() to something else), then click the green button (Submit new issue, if you're creating a new issue, or Comment, if you're posting to existing issue).
