Really, that's funny.

For me it was I who did that to the poor AI. I mean, those arrogant bitches came to me making threats...
Them: Accept or we will attack
They ask me to: Pay us XXXXX denarii

I just counter it this way...
My new proposal: Accept or we will attack
Them: Accept or we will attack

Of course, they accept and I got a transgression message (stating I've abused them diplomatically)

Stupid AI
