Yes, I brought up this issue (being reduced to 2 Movement Points when you have more than 2 upon loading a save game) a couple of times before I think, one quite a while back. It would be fantastic if it was fixed, as it is a case of saved games not saving all their information, or the game ignoring some of it when it loads, one or the other. And I don't think being in a city should count as being in a queue (especially since you can have more than 16 units in a city at once).
Best regards,
Steven.
