Playing my Karthadistim campaign, around 260 my economy started stagnating, and I was only making about a thousand mnai per turn. So I decided to save up to build a level one mine in Mastia. I was informed that I would be getting 2000 mnai per turn from this mine. However, once it was built I saw that I was only getting 660 mnai per turn. All that saving for nothing.
Is this something I did wrong? Is it a bug? Or does the level one mine in Mastia only produce 660 mnai per turn, instead of the promised 2000?
