THIS IS NOT THE SUBMOD. THIS IS THE BACKUP FOR UNINSTALLATION!!!!!
There are 2 Files you need to overwrite. The "export_decr_character_traits.txt" and "campaign_script.txt".
After downloading, extract the backup.7z file and move the data folder in it to your DaC folder. That should automatically overwrite the files. If it doesnt work move the files manually to the correct folders. Thats it!
