I'm wondering about the EMP operation. I noticed an enemy city I EMP'd built a tank on the next turn. I reloaded the earlier autosave and scanned the whole sea area around the city to make sure the tank did not arrive from a nearby area.
I suppose it's still possible the tank was drop-podded, but this seems unlikely. I have EMP'd most of my enemies cities and he still doesn't seem to have trouble nuking me and performing orbital bombardements on a much to regular basis.
So I'm starting to wonder if the EMP is bugged or has actually no effect on AI cities.
