I have the Blood and Burning DLC for Total War: Attila. But after I played with mods. I checked the settings menu, and the 'Enable Blood' checkbox isn't listed.

I tried disabling all my mods.
I also tried reverting back to vanilla with the mod manager.
I don't know what to do, and a reinstall would be really inconvenient, if there's anyone who can help, I'd really appreciate it.
