Hi, I can't find any reference to this in the forum. Are land mine and naval mine units currently disabled? I'm playing v37; in my recent game, I got the mine warfare tech; the movable mine units and the minelayers/sweepers show up in the svevopedia, but I can't build any of them. I made sure I have all the requirements etc. The only thing I can build is the Landmines city building. In this game I got the tech through the Encyclopedia, could that be the problem? But the AI is also not building any mines. They would be cool to have.
