It was your assured claim that it "got patched", so I thought you had the supporting info at hand and I'm leaving the burden of supporting your claims to you.
Ahh, the "burden of supporting my claims". No, I actively play the game and remember things that happened both in my games and in the patches that affected them. Much like you recall an anecdote of it happening to you. I don't have the correct line of patch notes in the (nicely styled, but horrendous to navigate) 2K / Civilisation patch notes webpage. The thing about good faith is it requires, well, that. Feel free to not believe me if it helps you. Feel free to look it up yourself if you actually want confirmation. I'm not lying, what can I say. I'm not even sure what providing the patch note would even do? Would it help you at all? Would it change the point you made?
My argument was that the AI in VII is better than in VI. There are more reports of it competing with players, which seems to be a first going back as far as V (though my memory, as vast as it is, struggles with going back a decade with any real precision).
The main* thing that hamstrung it post-release was the forward settling. There were of course other issues (there was a fantastic early mod here on CFC where someone really dug into how the AI was working, and diagnosed various improvements over time to its behaviour). None of this is controversial to claim. None of this, apparently, requires the burden of supporting evidence. Apparently?
Your argument is that the AI in both is poor? I'm not sure what your point
is, exactly. Is it meant to complement my point? Are you nitpicking my claim that VII's AI is better than VI's? I still don't understand what you're trying to say. I agree that the AI should not be
prevented from forward settling. With that in mind, I fail to see the relevance of an anecdote given the prevalence of forward settling behaviour at (and near) the game's release. If the AI still, situationally, forward settles, then that could be the intended result of what it is trying to do at that time.
The original context was that the AI was degrading between entries. I disagreed (and still do). Your contribution was to pop up after I mentioned a prominent issue being addressed to question said claim because it happened once, or twice, or however many handful of times around a certain patch. Where are we going with this? I think we can both agree that improving the AI would be a good thing for the game (for any video game, really).
EDIT - to demonstrate that I am interested in an actual discussion, I found a mention of settler AI in 1.1.1, but it's very vague. Directly from the Game Update Notes page:
Improved AI scouting and Settlement behavior.
So treat this as whatever confidence you have in "improved" vs. "addressed". Like you said, preventing it was probably not the outcome. But reducing it compared to what the AI was doing on release? Definitely. A lot of people were talking about it.
*main being both the perceived impact for players (as active behaviour is noticed more than, say, poor handling of city growth mechanics that only manifest more slowly over time), and the immediate impact on the earliest Age in the gameplay flow (Antiquity)
