I honestly don't know what is happening, but during Act 3, Mission 5 (Revolt), my Settlers keep losing the ability to build houses! If I save the game, whether quickly or with a name, and reload the game, the option disappears. I don't have any mods in my proto.xml file. Has this ever happened to anyone? What did you do? I can't play this mission properly without being able to build more troops! Oh, I'm using Windows 7 on my super computer with lots of everything. Can't be the computer.
