• Once past the Stone Age, the split columns for workers/buildings collapse into one. This isn't a major problem until the Renaissance, when the bottom entry for Workers (glassmakers) overlaps with the Buildings "column", meaning you can't hire any glass workers. It stops progress altogether once you're in the Industrial Era, as you can't do much of anything without concrete.

• Is there ever any reason to hire farmers instead of hunter/gatherers? The latter get significantly upgraded from tech and seem to remain superior well into the game, as well as requiring no buildings or space.

• What are Bronze/Iron weapons and armour for? What do the Palisades/Walls improvements do?

• The Renaissance tech "Larger Quarries (Tier 3)" requires steel ingots, which you can't make at that tech tier. Maybe move it back to the Industrial Era.

• I've met all the stated needs for the workers, but they're still furious with me. How do I get them to like me?

Minor bug: I seem to be able to hire marble masons without needing any quarries.

I did originally own a bunch of quarries, but razed them for space (since there's not a huge demand for marble). I can apparently keep the masons on without anywhere for them to work.
