Causus Belli - Holy War

[knighterrant81]

I'm playing Poland and Pedro II has converted two of my cities from Catholicism to Taoism. I also have the DIplomatic Service Civic researched...

...But I am not getting the Causus Belli for Holy War.

Does it have something to do with having denounced each other?

Declaring war with a cassus bellus only work in situations where you can declare a formal war. So yes, either player must have denounced for at least 5 turns.

 

[knighterrant81]

We've both denounced each other. Its been more than 5 turns, and I've gotten the holy war causus belli before when I haven't denounced.

Then you will need to provide a more information.
Are you using any mods? Any bit of information that could help resolve this?

Isn't Reformed Church civic also required?

Have you founded a religion?

I remember the "promise not to convert my cities" option was bugged prior to the Australia patch. It appeared when you converted one of their cities, instead of the other way around.
