Hey all! I noticed with the 1.4.0 Patch (though this was likely an issue already) that many generic units weren't able to upgrade into unique units, instead upgrading into the unit after. I realized (with the help of Pelo McSoy) that Civ 3 has its own method of upgrading generic units to unique units and that when I corrected what I thought was an error I was actually creating one. Thankfully, I've fixed it now so all UUs should upgrade properly!
