I was referring to the scenario of a capital-less nation conquering someone else’s capital which I doubt was contemplated. Or if it was, they thought it required no special handling.
Yes I was addressing that scenario. That’s a scenario which is so common throughout A&A that I would be flabbergasted if the lack of special handling was an oversight. Even in the original game that happened all the time: Moscow falling to Japan the turn before Russia conquers Berlin (as the 3rd attack in a 1-2-3 with UK and US) was a typical endgame outcome in Classic. As far as I’m aware, none of the rules related to capital capture mechanics have changed since then.
