[bug] TC range does not increase with Fletching/Bodking Arrow/Bracerupgrades, but Tech Tree says so

In any case, I tried figuring out whether the new sheep-scouting behaviour is a “balance change” in DE.
It might be, and I’d be just cluttering the forum, which I don’t want.

How would you go about figuring that out, specifically? I’ve been looking for a list of all changes that Age2: DE made, but I must have been blind.
If that exists out there, I’d like a link. [call me untalented at googling, if it’s findable, I deserve that]
