First, I'm sorry I don't have a screenshot to post. I'll explain what's going on (0.40q) ...I have astronomy, mithril weapons tech, and whatever tech lets you get phalanx units. It's a standard size islands map with 12 civs. My main islands did not have mithril, so I decided to go to war to get some. I took over a city that had mithril two squares away from it, in its cultural borders. However, that mithril was not on the same island as the city: you have to cross water to get to it.
Anyway I have the city, my culture covers the mithril, it's within the fat cross, and I have a mine and a road on the mithril. The city is working the square. Yet, I do not have the mithril resource in the city screen and none of my units were upgraded to mithril weapons (I have various T3 units including the lanun hero, phalanxes, beastmasters, crossbowmen). What gives?
