I don't know if this could be considered a bug.

I've noticed that since I upgraded to 1.27 that the Mandatory Retirement in 20 years message no longer comes up in the year 2030.

did it come before? I cannot remember it but for CivII

Yup,just finished my first 1.27 UK PTW game, and there was no Retirement warning, and there always was before this patch.

(PS ,- I finished fourth by the score on Monarch level, :cry: ! my excuse is that my modded Barbarians with increased stats stopped me from expanding at the begining of the game :crazyeye: )

I have never gotten a warning 20 yrs b4 retirement. Oh well I'll just rely on my eyes to watch the year. lol
