So I'm on turn 261 as the Amurites on the Erebus map, after a few years away from Fall from Heaven 2. I'm using base Fall from Heaven 2 with patch O, and also the More Naval AI modmod. That's it. Suddenly my production, food, science and tax have dropped to 0 in every one of my cities. I didn't see any event notification or anything that might explain it. Basically my cities have stopped growing, buildings take hundreds of turns and technology research has ground to a total halt. No money, science, food or any other main resource coming in. I can't tell if the AI civs are affected or not, and I've skipped ahead around 20 turns but the effect still lingers. Any idea what the hell this is?
