Hi, I seem to be getting 4 happy faces in most of my cities in Despotism even though I only have 3 lux and no Entertainers/Entertainment. I do not even have Currency yet (much less marketPlaces). I have used a few pop rushes but it seems that now one more pop rush will make the 4th happy face in every city go away. Any idea why? Is there a clear description of how faces work somewhere on this site?
