Is the achievement bugged? I tried to get it as Rome last month, but chalked up the failure to the Roman bath. Tonight I tried to get it as Mongolia, no idea why it failed. The city already had its aqueduct, dam, and canal. I tried putting railroad in the city center and building a mountain tunnel both the turn before and the turn after the golden gate bridge completed, and did not trigger the achievement either time. The achievement has been at 0.1% for months. That doesn't prove anything, but is consistent with the hypothesis that it's bugged. Has anyone gotten the achievement recently? If so, any chance you remember the exact order you competed stuff in? Thanks! I'm running a large handful of mods, so I don't think my save would work for an official bug report.
