Koikatsu output log

output_log.txt should be in your game folder, where Koikatsu.exe is.

If it's not there, edit doorstop_config.ini in a text editor and change

redirect_output_log = false

to

redirect_output_log = true

then save it, restart your application and cause the problem again so it can be logged

You can also open the log directly from the game with F1 plugin settings -> Open Log
