When investigating bug reports, game client crashes, and other issues we sometimes require access to the log file generated at the time that the problem occurred. Here’s where to find it.
(User)\AppData\LocalLow\Eleventh Hour Games\Last Epoch\output_log
~/.config/unity3d/Eleventh Hour Games/Last Epoch/Player.log
NOTE: This file is reset each time you start the game. In order for it to contain useful troubleshooting data, please retrieve it before you open the game client again.
