[1.05] [gameplay bug] - Zone of Control
I've noticed that in 1.05 (and indeed, earlier version) the accuracy of detecting whether or not objects are within your "zone of control" (expanded border of your cities). For example i was able to build on a gold mine that was 1 tile out of my zone of control. But in other games, there have been improvements that have just been within my zone that I could not build upon. Same goes for NPCs and trying to recruit them.
