I downloaded the mod, and unzipped the files. I start the game, choose the mod, and the game restarts. I can see it loading the new custom house files, but when I get to the game the custom house isn't available to build. I have built the docks, lumber mill and warehouse expansion, but it doesn't show up in my build screen. I haven't used any mods before in this game, so maybe I'm doing it wrong. I copied the files into the mod folder as previously stated in this tread, so what am I doing wrong?? Any ideas?
