I did not get any civics points when researching writing...or at any other time in the whole ancient era. (even though empire stability has stayed in the 40-60% range the whole time...I extended the ancient era to try and get wonders to boost stability.). Not at computer right now so I can’t get save file, but I expected to get a civics point to spend after researching writing, or at least after some time.

Saves below.  It seems it cleared up after founding a second city?.... but I should have gotten one with writing. (conquering a second city should probalby work as well

That is definitely helpful, So similar to the religion model?  ...Looks like I’ll be pumping up  the food in my capital.  Thanks...

Not sure it helped, I have cities size 6, and no civics points
