So its my one year today and last night in anticipation I reviewed my nation. I see everything is in order, etc. I log in this am to find its my birthday and my citizens are +5 happy, however, I have like less citizens. What the heck man? I went from around 66K to 57K working citizens. I use the money I had left to buy infra. I had enough to gain back about 1K citizens before collecting taxes. I check the game update and nothing is posted about a recalculation of formulas.
Edit: grammar/spelling
