Acularius is right, settled citizens still get the +1

from Patrician. I just got to the point where I can take Patrician and found that it is assuredly so.
Whatever the fix was to remove that during Patrician seems to have not worked.
Giving a save for show where one can mouse over the citizens in any city and see that they get extra gold.

to Patrician didn't remove the extra

from Settled Citizens. It's stated on mouse-over that they don't get that +1

but in the mouse-over on

in the city screen it's still added +1

per Settled Citizen.
The only way I can see to fix it, and will try that later when I have time, I think might be to remove the +1

from all specialists and add it specifically for those that do/should get it.
Cheers
Edit: Back and did these changes:
Removed the +1 from all specialists.
Added +100%(of 1) to all specialists except Slave and Citizen.
It's a dirty fix, I know, but at least it works. My Patrician is now not OP (with 400+ slaves as settled citizens, yes, I know, bad, but it's roleplaying with Rome's Augustus so fits my scenario).
