I didn't know anything of the kind. I'm not being obtuse here, I rarely am anymore. Bad habit from when I was younger. I try not to read into things, because things can easily be mistaken or taken out of context (and however much we may disagree, that's not something I'm fond of).
You're sad that it's a surprise that the AI was fixed, then? Is that more accurate? Surely, given that aircraft AI is one of the most-publicised and definitely one of the most impactful weak spots of the AI, then surprise or not this is still great news. It completely changes how I would play the game if I were trying to uncover AI patterns (I don't personally, I normally play Civ to relax as I have very little free time at the moment. Not compared to my old CiV / BE days). Personally, I'd take the good news, and not the sadness
