City resource allocation

[BayushiNezumi]

Anyone else having an issue creating resource dependent buildings in cities that actually have the improved resource two tiles away. I built a city with military units in mind and it wont let me build the forge or stables despite the fact that I have horses and iron nearby. It seems as though these particular resources are allocated to other nearby cities as they can build the buildings in question. I am working those tiles with the city I want to build the stables and forge in but no go. Guess which order you build your cities in counts?
