Fired up a game and am seeing it as well.

You're not alone. 

That's easy to check; just look at the techs we have in common view on the diplomacy screen.

But I highly doubt that a couple of Cakewalk AIs are going to beat me to the punch on anything, really.

Agreed that it was working properly in the beta.  Not sure what happened there.

I would agree that it's probably disregarding the setting, but game saves are version-specific; although they may work, after a fashion, in another version, they derive the bulk of their mechanics from the version they were started in.

Meant to edit the above in case it wasn't obvious, but it seems to be-it's easily testable with a tough to suicidal teammate and a bunch of cakewalk AIs.

Fixed.  Not sure how/when the logic error was introduced.
