Hi. I like to play with charismatic leaders and in my army production cities I tend to have at least 4 great generals so every new unit has level 4 promotion. I prefer having smaller, but well trained (experienced) army. I don't like that when a unit has more than 10 experience points and I upgrade it to newer unit, it's experience counter resets to 10. I know that this behavior was in original civ4 as well, but I think it's a bug. Right now when I have a unit with more than 10 experience points and it's missing just 1-2 experience points to reach next level, I can't upgrade it until that unit receives those missing experience points and reaches next level. Could this be fixed?
