Upgrade units in team game

[spuffin]

I am playing a team game and I can't upgrade my unit that is in a teammate's territory. It is my understanding that a patch a while back limited the ability to upgrade units from in "friendly" territory to only *your* territory. The two problems with this are

1) The text when highlighting the upgrade option still states "friendly" territory which should include friendly city states and allied city states

2) Even if #1 is just a documentation issue, teammates are the equivalent of your own territory and would share the tech

Essentially I can understand if you cannot upgrade a unit in a city state because theoretically they wouldn't have the tech to share with you and that tech has not been communicated to your people in the field after its discovery. That argument doesn't hold water in a team game since everyone on the team shares the tech. That argument also doesn't explain why you can upgrade immediately after conquering a civ regardless of how far it is from your territory but that's a discussion for another time.

Apologies if this has been covered but all I could find was the city-state issue mentioned above. I can upload a save if this is indeed unintentional behavior or if I missed it in the documentation somewhere.

I share the sentiment. It may not be a bug, as the upgrade ability has been deliberately patched out, but I found it strange as well and reported it a long while back: http://forums.civfanatics.com/showthread.php?t=437659. Maybe you're calling this the 'City-State issue', and yes, I don't play your type of team game, so for me it was just about the City States, but aren't they considered to be in your team when you're allied with them? I'm still not immediately grasping the logic why healing and embarkation works like it was your own territory (especially with embarkation they are considered to share your tech), but for upgrading of equipment it doesn't.

To compare; the enhancer belief Defender of the Faith gives 20% combat bonus near 'friendly cities' that follow your religion; these can only be your own cities as well?

Optional - I agree with you; I would prefer that we actually be able to upgrade in ANY friendly territory. I was just trying to come up with some "logical" reason for it to behave the way it is.

For what it's worth, here are three screenshots depicting the problem - all of which were taken on the same turn. Note the text that appears when hovering over the upgrade option.
