- Heroes now cost 1 iron to build, the weapons to kill the Vertex don't make themselves.

- Somehow the Unit flag for the Hero hadn't made it into the final version, oops. Well it's back now, no more wondering why you have a small army of settlers.

- Tweaked Yuna's UA to give yields per 4 citizens since it was snowballing out of control by the Classical era if Yuna had even a moderate amount of food, this should hopefully put a brake on that progression somewhat.
