Perhaps this has already been mentioned somewhere and I missed it. I'll post anyway.
At 4000 B.C., if you've already settled your city, Civ does not prompt you to select which tech you'd like to research; it does so on the next turn.
The way it went on my first turn was like this: I usually select what I'd like to research before entering the next turn (3950 B.C.?). This time I forgot, and into the next turn it prompted me which tech I'd like to research. I selected Iron Working. It said it'd take 36 turns. So, at 3950 it'd take 36 turns.
Now, I restarted the game at 4000 B.C. to see if selecting before hitting Enter would have made a difference. I settled my city, selected the tech I wanted to research, and entered the next turn.Now it was 3950 B.C. and Iron WOrking would take 35, not 36, turns to research because the last turn counted as researched.
So I guess the bug would be that the research prompt comes too late; when it pops up, you've already lost the opportunity to be 1 turn up in research.
Am I right?
