Some buildings have their requirements in same tech columnSeems like Marble is not enabled at all, or too late (my civilization did not achieve yet the Masonry). I have a source of Marble with Early Quarry connected to the city with Path and in city radius. I am unable to build Stonework Workshop, nor Stele.
I do not have an access to Stone and/or Obsidian.
