I know, it's been years. But people have been complaining about crashes and the old hotfix I updated got taken down. No promises this will work, but give it a go. Drag it into your mods folder and make sure to overwrite the campaign_script.txt file. If you weren't prompted to overwrite the file, you put it in the wrong place. This removes the Others script from the campaign, but they are still playable in custom battles. Enjoy!
Thanks chief!
Do you know why my game keeps crashing when I kill the last family member to a fraction?
