I built a second city next to an iron deposit and built a mine immediately, something in that build request was wonky, and three ended up getting placed, and in the wrong spot(s).  A few turns later when they were finished I clicked on the city to see the surprise three new mines and the game crashed back to desktop.

I really hope you guys have some automated tools for reading these things.
