I have unlocked the steel making tech in the Ancient Warrior scenario 4 separate times. Once on hardcore and once making sure it was the last available tech and the achievement will not unlock. I am on Xbox. This doesn't seem to be a very popular game on the console and can't find anything on the subject. Is there anyone who has run into this issue and figured out a way to fix it? Or is there somewhere I can get in contact with the right people to bring this issue to light?

I also unlocked all techs in just under 5 hours on one attempt as well and the Express Evolution didn't unlock either. I don't know if that's because it starts with some techs unlocked already though.
