Here it is a CoA bug i came across:

Playing as Spain and i'm allied with The Papal States. France and The Papal States(also allied with France) are at war with England. Aragon(also allied with France) joined a coalition against me. I started a war against Aragon and called The Papal States to arms (yes you can) and guess what happened ? The Papal States didn't join the war.

The Papal States can't be at war on the same side as France against England and on the opposite side with you against Aragon at the same time. Thus one of the Papal States or France can't join your war, and I think the defender always gets priority in the case of conflicts like this.

I'm pretty sure it's not due to prioritizing the defender, as it's sometimes possible to break your allies alliances by calling in cobelligerents, and sometimes not. I suspect they are being called in alphabetically by tags, but I don't know for sure.

As for the problem of the op: The bug here is that the UI is telling you they will join, as the game isn't properly checking all the diplomatic relations of the allies of your war target before you actually declare the war.

This has been happening for some patches now, I reported this about a month ago, not sure if they'll bother to fix it in 1.25, but I personally doubt it. UI is pretty glitchy nowadays (when you declare war on someone with allies, and they say they will accept, sometimes they won't)

Actually I think that's a common bug, I see it all the time in my games.

There are, unfortunately, many instances of the war declaration screen essentially lying to you. By now you jsut have to rememebr the cases under which it will lie and how to check and make certain manually.

Sometimes this is impossible. I've had a game completely ruined by this bug when it said their ally would join but they actually didn't, and then when I wanted to get to the target country, I couldn't because the ally was the only access through to their lands.

And this really confuses me, because both of them were rivaling me back and had no loans.
