Is this a bug or interesting play by AI?

France is subsidizing Granada who is fighting with France's ally Castile. France is hostile towards Aragon. Aragon is in union under Castile but is not in war against Granada. Is France wasting money on fighting it's ally or is that some elaborate strategy I don't understand?

Is France friendly to Grenada? Only explanation I could think.

How much in subsidies? There's some kind of bug involving subsidies since players have sent screenshots of being given 0.00 in subsidy income.

I didn't think about it but that's not it. They are neutral.

1 ducat with change so that's not it either.

That´s likely the leftover subsidice from a war that happened earlier... When AI checks for cancelling that, they are VERY slow to do it even after the war is done... If you restart it should stop immidiately

This was Granada's first war.

It's because they're fighting Aragon. Allied to Castile or not, France want Aragon dead..you know.. because logic.

But Aragon is NOT in this war.

That's not a bug, that's a different word creative programming.

They want to support you, but they do not have the funds necessary.

Like a colony that starts colonizing a new province and has -30 growth per year for no apparent reason until you realize they have their colony maintenance cut down way below 40% because they'd go bankrupt in a few years. They would go bankrupt anyways, but you get my point.

EDIT: As for OP. They do not calc those things.
The path is "I hate x. Who is at war with x? I will help y".

There's nothing more to it.

I added a lot more to it but I don't know how much is left as of 1.19. There was a problem in AI having no way to slow down countries it was constricted by rivalry with or attitudes to, but they can (at least on Hard+ in 1.17-1.18) secretly (or not so secretly if you pay attention) work against what they perceive as the greatest threat. Before you claim bipolar, keep in mind there's a lot of stuff visible in GUI that severely limits what AI can do about a growing threat because they must be "friendly" or whatever.

However, I can't recall if it's intended to happen against allies..
