    I have an Archer stationed in a City with Iron (with Mine and Road connection), but the "Upgrade Unit (Crossbowman)" icon in the unit's Action Box is greyed out. Why? Do I need Barracks to upgrade units?

    Edit 1: I just moved the Archer to a City with Barracks, but I still can't upgrade the unit. What else do I need?

    Edit 2: OK, I got it - I was short on money... Duh!

    The great thing is that you don't need to be in a city with a barracks or even in a city! Cashola helps though, as you discovered. :)

    Your units don't even need to be in a city either, they can be upgraded as long as they're within your borders!

    however, there might be a greater cost for upgrades in the field, this warrants further investigation.
