I feel super stupid, basically instead of pressing enter (to rotate through the available units) I pressed both the Delete and the Enter keys. My spearman was supposed to move and defend my worker...
It was located on the highlighted tile and was going 2SW.
My tech strategy : double prereq whenever possible. I've been in the top 5 GNP for the past 10t because of that. I'm not going to get many (if any) first to bonuses from now on so I can at least pay the cheapest price possible for each tech (I even considered priesthood before writing and am still considering it).
How much is the prereq discount BTW ? 20% ?
Edit : answer is yes, but priesthood will have to wait. I don't want to delay maths.
yep, 20% per prereq tech, additively. it only counts arrows though; rereqs without arrows, like how Monotheism requires Masonry or how Compass requires Sailing, don't give a bonus.
