Well, lets use a simple example with Iron upgrading warrior to swordsman.
So lets say I have 5 cities, A, B, C, D, E, for simplicity.
Town E is the furthest away from A, my capitol and also has the smalles pop. of lets say 2. This town E also has Iron in its vicinity, so I take a worker and connect the Iron to town E which is in turn connected to all my other cities and A the capitol.
I am then able to build swordsman at every town connected, but upgrading is a different story. It seems I can only upgrade my warriors to swords If i put them in my capitol, or another random city with a somewhat large population.
this always seems to be the case for me... Only certain cities allow me to upgrade units and I have the Gold to do it. It just doesn't seem to make sense, and gets annoying when I have to take my units from border cities all the way back to a capitol or one of these 'larger' cities that allows me to upgrade. Its also pretty frustrating when I have to wander from city to city until I find one that does upgrade, and Im wasting my units time when it could be somewhere else defending or fighting.
Is there a reason for this, I can't seem to find anything that wouldnt allow me to upgrade at certain cities when I zoom in. This isn't only for Iron and swordsman, its also the case for salpeter and upgrading pikes to muskets. My cities are all connected and can all build the units, but only certain ones are able to upgrade, and there seems to be no rhyme or reason behind it. I seem to remember playing civ 3 back in the day that I could upgrade units anywhere as long as they were connected.
