I constructed a city next to an iron deposit in hopes of slapping down a mine on it. Well, the game let me slap down 8(!) mines on a tile below the city, while the mine was above the city. As you can immagine, the logistics of running the 8 story mine miles and miles away from the resource would naturally perplex any engineer, and it caused my computer to crash shortly after they were constructed and I tried again (in vain) to build a mine on the resource.
