Sometimes you’ll have a troublesome config error that you can’t figure out even with the troubleshooting YAML tips. When that happens, you may want to roll back a specific config file to its default values.
config <section> command in-game. Other settings in other config files will not be affected.
If your web portal is functioning, you can edit the config file using Admin->Setup and click “Restore Default Values”.
If your web portal is not working (usually because your top navbar settings were messed up), you can restore a config file in-game using config/restore <file>.
If none of that works, you can also recover a default file from the shell. In your aresmush directory, run:
cp install/game.distr/config/SOMEFILE.yml game/config
Just specify the name of the file you wish to restore (e.g. demographics.yml).
