Where are the logs

When you report a crash, attach the logs so we can see what happened. Zip them right after the crash, before starting the game again: the logs cover the last two launches only.

💻 Windows

Paste a folder path into the File Explorer address bar to open it. The Crashes folder may not exist, that is fine.

What Folder
Game logs (your saves are next to them, in Saves) %USERPROFILE%\AppData\Roaming\Captain of Industry\Logs
Engine log, Player.log %USERPROFILE%\AppData\LocalLow\Mafi Games\Captain of Industry
Crash dumps %USERPROFILE%\AppData\Local\Temp\Mafi Games\Captain of Industry\Crashes

If the whole PC rebooted or froze, the log is probably cut off. Add --flush-after-each-log --full-flush-logs to the game's launch options (right-click the game in Steam > Properties > General), reproduce the crash once, and attach the log from that run.

🐧 Linux and Steam Deck

The same folders live inside the Proton prefix.

What Folder
Game logs and saves ~/.steam/steam/steamapps/compatdata/1594320/pfx/drive_c/users/steamuser/AppData/Roaming/Captain of Industry/
Engine log, Player.log ~/.steam/steam/steamapps/compatdata/1594320/pfx/drive_c/users/steamuser/AppData/LocalLow/Mafi Games/Captain of Industry/

📎 What else to include

  • The save file. For a large save, a Google Drive or Dropbox link that anyone with the link can open.
  • Your CPU and graphics card, and whether mods are installed.
  • What the crash looked like: an error box, a black screen, or the whole PC rebooting.
